Is this battery compatible with my electric outboard motor?
Yes, the LiTime 36V 100Ah battery is compatible with most 36V electric outboard motors, including brands like ePropulsion, Torqeedo, and Newport. Please check your motor’s voltage and power requirements to ensure compatibility.
Is this item suitable for gas propelled/ fuel powered outboard motors?
No. Designed for electric outboards, this OBM battery powers electric outboard motors. Beyond marine, it's perfect for 36V and 72V golf cart, home storage, off-grid, etc. If you're looking for a battery for your fuel-powered outboard motors, we've introduced starting batteries to suit your needs: 12V 20Ah starting battery and 12V 140Ah dual purpose battery.
What are the difference between trolling motor batteries and electric outboard motor batteries?
LiTime electric outboard motor batteries are versatile, being suitable for both electric outboards and trolling motors.Conversely, LiTime trolling motor batteries are engineered specifically for trolling motors and are not suitable for electric outboards.
Electric outboard motor batteries must cater to higher current demands and more dynamic power requirements. These batteries are designed to deliver bursts of high power necessary for propulsion and rapid acceleration, in addition to sustaining prolonged periods of operation. LiTime 36V 100Ah OBM lithium marine battery support 500A/1s surge discharge current, which ensures the battery able to withstand high current at start-up. Moreover, it able to discharge at 1.2 time the norminal current for 3 minutes, which much longer than those trolling motor batteries, sustaining prolonged periods of operation.
Read on Electric Outboad Motor VS Trolling Motor for more detailed information.
Is this a dual purpose battery in that it performs as a starting/cranking battery but also as a deep cycle battery for electronics?
No, this battery is not a dual purpose battery and can't be used as a stater battery. It is a deep cycle battery specifically for electric outboards. Our cranking/ starting batteries has launched (both marine starting battery and dual purpose battery that supports cranking/starting and deep cycles), click here to select the cranking/ starting battery or dual purpose battery you need.
Will this battery avoid supplying too much voltage, current, or heat to the motor?
All LiTime batteries, including this item, are provide 5 basic protections: overheat, overcurrent, overcharge, overdischarge, and short circuit protections. More than that, with LiTime newly upgraded 100A BMS, this battery provides more than 20+ protections (including the above 5 basic protections): low-temp cut-off protection, auto-recovery after overload protection (30s), pre-charge function, moisture and salt-spray resistance.
How long can this battery power my electric outboard motor?
Runtime depends on your motor’s power draw. For example:
- A 2000W motor (~55A draw) can run for ~1.8 hours at full throttle.
- Lower speeds significantly extend runtime.

I’ve got 5 or 6 LiTime batteries but these newer models with blue tooth is a game changer. I’ve only had the chance to use the boat three times since I got the new 36 volt battery but I only used a few percent. I’m not so sure I’m gonna need the dc to dc charger I installed. Time will tell. I’ve had pretty good luck with LiTime and any problems have been taken care of. You can’t beat it for the price. Literally half the cost of the other brands. Half the warranty also. Works for me.

On my 21ft bennington I used the battery for spot lock an alittle trolling for 12hrs an at the end of the day I still had 80%
A
I replaced my 3 lead trolling motor batteries and a 4 bank charger with a single Litime36V battery and charger. Now the back of my boat doesn’t sit as deep in the water. I have gone fishing once so far and I’m highly impressed. I fished 7 hrs and was on the trolling motor hard giving the new battery a good workout. When I got home my battery was still at 91% by the way I love the Bluetooth connection to monitor my battery. So I can get a mi” minimum of 2 trips before needing to charge the battery.. I highly recommend the Litime battery both for the price and performance.
R
Bought this battery but it was way too big for my compartment on my boat. Thing is a power horse
B
Have not used it yet. Had to go to the us to buy this 12v 100ah not available in Canada only the 50ah. 63lbs pounds is ultra light for a batterY with this output. Very excited to no longer have battery anxiety when using the trolling motor all day.make sure you really measure for spacing for this battery although lighter and smaller then 3 12v in series it has a very big single footprint. This thing is going to be amazing
B
I am a licensed marine installer. These batteries have been fantastic. No issues.
A
So far so good. The weight of this 1 battery is 33-40% the weight of the (2) 12V deep cycles it was replacing. The size is about the same as 3 batteries. Happy with my purchase and will recommend LiTime to anyone who asks.
K
I’m amazed at the power and durability of this battery. I use my Ultrex trolling motor all day and still have 80% left over with no reduction in power or speed.
