Lithium Trolling Motor Batteries

battle born battery lifepo4 100ah 12v mA few years ago, lithium batteries were considered as something exotic, futuristic, but with the improvements in technology, lithium batteries more and more present in our everyday lives. Lithium trolling motor batteries initially cost several times more than the AGM SLA batteries of the same capacity, but they can save a significant amount of weight and can outlast AGM batteries 5-10 times.

These are the reasons why lithium batteries are becoming more and more popular as lightweight but long-lasting deep cycle trolling motor batteries.

Electric Trolling Motors Intro - Features and Specifications

Electric trolling motors are used when quiet, simple, and efficient propulsion is required. Main power sources are onboard batteries that supply the required current at rated voltage. Most smaller electric trolling motors operate at 12 volts, but other voltages are used as well:

- 12V is used for a thrust up to 60-65 pounds,

- 24V is used for a thrust up to 100 pounds,

- 36V is used for motors that provide more than 100 pounds of thrust,

- 48V is used for electric trolling motors that provide more than 150 pounds of thrust and for electric outboard engines, usually up to 7-10 HP.

By increasing the operating voltage, maximum currents are kept under 50-60 Amps, which is very important for keeping the cables not too thick.

The following table lists the most popular electric trolling motors:

nv 62 tDuring operation, electric trolling motors are not constantly pushed at the maximum - they must have a certain power reserve in order to be able to push the boat in emergencies.

But, just like electric trolling motors, trolling motor batteries must be dimensioned to include certain power reserves, in order to be able to power accompanying motors in emergencies as well.

So, when calculating required battery capacity, it is recommended to always use maximum motor current - and even then add some reserve, just in case.

A little bit of math: If you have Newport Vessels 62lb Thrust NV-Series electric trolling motor with a maximum current of 58 Amps at 12 volts and you want to have autonomy of at least two hours, your battery must have 2h capacity of ~120 Ah.

Since the capacity of the batteries is a value measured when the battery is being discharged with a constant current for 20h, the actual 2h capacity is lesser than 20h capacity, especially for AGM SLA batteries.

upg ub121000 1mFor example, one of the most popular 100 Ah AGM SLA batteries is UPG UB121000 Deep Cycle AGM Battery and it features:

- 20h capacity of 104 Ah,

- 2h capacity of 'only' 62 Ah.

Note: these values are measured at 77°F (25°C), for the new, fully-charged battery being discharged down to 10.5 volts (1.75 volts per cell).

In order to be able to power Newport Vessels 62lb Thrust NV-Series for two hours at full throttle, one must connect two UPG UB121000 batteries in parallel for effective 124 Ah capacity when the batteries are discharged for 2 hours!

Of course, this also doubles the weight of the battery pack from 64 pounds (29 kg) to 128 pounds (58 kg) - and that is rather heavy just to carry around :)

And that is where lithium trolling motor batteries come to play!

Types of Rechargeable Lithium Batteries - IMR, INR, IFR, and ICR Lithium Batteries

There are numerous potential lithium-ion battery chemistries, but most common are sometimes 'hidden' via abbreviations like IMR, INR, IFR, or ICR. These abbreviations describe actual battery chemistry:

- IMR lithium-ion batteries feature LiMn204 (Lithium Manganese Oxide) chemistry. Their nominal voltage is 3.6 - 3.7 V per cell, with the maximum recommended charging voltage of 4.2 V per cell. IMR batteries commonly have a smaller capacity but are capable of delivering large currents and are often used in the starting lithium-ion batteries.

- INR lithium-ion batteries feature LiNiMnCoO2 (Lithium Manganese Nickel) chemistry. These batteries are very similar to IMR batteries since they can provide plenty of currents, with slightly lower capacity. INR lithium-ion batteries are commonly used in starting and power tools batteries.

greenlife 12v 80ah lithium- IFR lithium-ion batteries feature LiFePO4 (Lithium Iron Phosphate) chemistry. Their nominal voltage is 3.2 - 3.3 V per cell, with the maximum recommended charging voltage of 3.5 - 3.6 V. They can't provide extra-large currents, but are much safer than other lithium-ion batteries and are commonly used as 'drop-in' replacements with some sort of Battery Management System (BMS) in place.

- ICR lithium-ion batteries feature LiCoO2 (Lithium Cobalt Oxide) chemistry. Their nominal voltage is 3.6 - 3.7 V per cell, with the maximum recommended charging voltage of 4.2 V. They commonly have higher capacities, but maximum allowed currents are often limited to just a few C. ICR lithium-ion batteries are used for low-current, deep cycle applications.

Note: there are other lithium battery chemistries on the market too, like Lithium Nickel Cobalt Oxide (LiNiCoO2), Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2), etc. These hybrid technologies often feature improved charging/discharging features with improved safety, but the cost of such batteries is still too high for everyday use.

Commonly, lithium electric trolling motor batteries are 'IFR lithium-ion batteries', featuring LiFePO4 (Lithium Iron Phosphate) chemistry.

They are the safest for use and with proper BMS they can safely replace AGM SLA batteries in most applications - trolling motor batteries included.

Advantages of Lithium Trolling Motor Batteries

The main disadvantage of the lithium trolling motor batteries is their initial price, which is easily 3-4 times the price of the equivalent AGM SLA battery of the same capacity. But, as time goes by, the price of lithium-ion batteries is becoming more and more acceptable.

The advantages of the lithium trolling motor batteries include:

mighty max ml100 12li- larger number of charging/discharging cycles. While deep cycle AGM batteries can withstand 400-500 cycles (at most) when being discharged down to 80% DoD (Depth of Discharge) or 20% of SoC (State of Charge), many lithium-ion LiFePO4 batteries with the proper BMS can withstand at least 2000 charging/discharging cycles commonly down to 100% of DoD (when BMS cuts off the battery), with some high-end models easily tolerating 5000 cycles down to 80% and even 100% DoD.

- output voltage of lithium batteries is much more stable during operation, although this depends on the built-in BSM and the rest of the electronics.

- lithium batteries are 2.5-3 times, sometimes even more, lighter than their AGM equivalents, saving plenty of weight.

- lithium batteries feature a very low self-discharge rate and can be stored for months (6-12 months) with minimal loss of charge.

- lesser drop of capacity when being discharged with slightly higher currents, etc.

On the other hand, the most important issues of rechargeable lithium batteries are:

- safety concerns: most lithium trolling motor batteries are Lithium Iron Phosphate batteries which are relatively safe to use. When combined with BMS, they are safe to use since BMS systems monitor the condition of the individual battery cells and the whole battery pack and act accordingly to protect the battery from unwanted events like overcharge, over-discharge, short circuit, low temperature, overheating, over-current, etc.

- connecting in parallel: lithium trolling batteries can be connected in parallel only if their BMS are intended for such use.

- connecting in series: lithium trolling batteries can be connected in series only if their BMS are intended for such use.

- lithium battery charging: lithium trolling batteries can be charged with intelligent AGM battery chargers with lithium battery charging modes, or using solar panels connected to solar battery charge controllers that feature lithium battery charging modes, or simply, by using dedicated lithium battery chargers.

Note: when connecting lithium batteries in parallel or series, use ONLY the batteries that officially support such connections. Also, always use only the batteries of the same model of the same manufacturer, preferably from the same battery batch. And be sure to connect them as recommended by the manufacturer (check the batteries' Owner's Guide) - lithium batteries store huge amounts of energy, and when used as recommended, they are safe, but when misused, they can easily catch fire or even explode!

Also, we have tried to verify every single bit of information in this chart, but things may change over time, especially with the introduction of new battery (sub)models.

greenlife 12v 260ah lithiumAs one can see, these batteries are much lighter than AGM SLA batteries.

Also, the capacity drop is not as nearly as the capacity drop of the AGM SLA batteries, and when not discharged with strong currents, there is practically no capacity drop at all.

For example, GreenLiFE GL260-260AH features:

- 260 Ah 20h capacity (13 Amps for 20 h),

- 260 Ah 13h capacity (20 Amps for 13 hours),

- 260 Ah 5h 12 min capacity (50 Amps for 5h and 12 minutes).

So, no capacity loss for currents up to 50 Amps - that means that this 80 lbs battery is able to power 50 Amps load for slightly more than 5 hours. An equivalent AGM battery (or battery pack) would weigh at least 170 or even more pounds, not to mention the other issues like the lesser maximum number of charging/discharging cycles, slower charging, etc.

Lithium trolling batteries initially do cost more than AGM, Gel-cell or wet/flooded lead-acid batteries, but in the long run they really save money and effort.

Of course, there are other 36V lithium deep cycle batteries on the market that can be used as excellent electric trolling motor batteries - feel free to check the comparison chart and choose according to your own needs and requirements.

36-volt lithium trolling batteries are commonly used for trolling motors usually in the 100-150 pounds (45.3-68 kg) range, but they are also very often used for 36V golf carts, RV house batteries, for electric vehicles, as high-power ultralight inverter batteries and similar.

Some of these batteries allow the user to connect them in parallel in order to achieve higher capacity, although the actual documentation from some brands is lacking sufficient information, to say the least.

Personally, in that case, instead of getting, for example, 3 (three) 36V 100Ah batteries and connecting them in parallel, perhaps it is a better choice to get 3 (three) 12V 300Ah batteries from reputable brands (with proper documentation, user support, a large number of positive reviews, etc.) and connecting them in series.


48 Volt Lithium Trolling Motor Batteries

48-volt lithium batteries pack a serious punch and are able to store plenty of energy. That is why 48-volt lithium batteries are commonly used for 48V golf carts, 48V RV house batteries, as energy storage batteries in off-the-grid systems, as backup batteries, and similar.

As trolling batteries, 48-volt lithium batteries are not very often used because of the limited number of 150+ (68+ kg) trolling motors on the market - such motors are strong enough to be used as outboard electric trolling motors.

But, outboard electric trolling motors in the 5-10HP range are becoming more and more popular, and that is where these lithium batteries are finding their purpose as well.

Of course, there are other 48V lithium deep cycle batteries on the market that can be used as excellent electric trolling motor batteries - feel free to check the comparison chart and choose according to your own needs and requirements.

Since 48 volts is a rather serious voltage, not all 48 volts lithium batteries support connecting in series for achieving even larger voltages (96V, 144V, 192V, etc.).

But, due to the 48 output volts, which requires 16 (sixteen) 3.2 volts cells connected in series, the actual capacity of these batteries is relatively low, with the most reputable brands making models featuring 24, 30, or 50 Ah, but with their BMS supporting parallel connections of the larger number of batteries (sometimes even with no limits).

On the other hand, if 100Ah @48 volts is all that You need, consider Ampere Time 48V100Ah lithium battery, but don't forget to check other models as well ...


Long Story Short: Lithium trolling batteries are not part of Science Fiction anymore. They do cost more, initially, but in the long run, they save money and if the batteries must be carried regularly, they also save plenty of effort :)

Also, these batteries are commonly used in off-the-grid applications, as RV house batteries, solar batteries, golf cart batteries, various electric vehicles, etc.

Before ordering a new trolling motor battery, consider lithium batteries as well, just be sure that they feature good BMS systems that in combination with battery features (dimensions, capacity, maximum current), fit your needs and requirements.

 Don't forget - safety first!
