FAQ

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 12V 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 item suitable for gas propelled/ fuel powered outboard motors?

No. Designed for electric outboards, this OBM battery powers electric outboard motors, trolling motors, and onboard electronics. Beyond marine, it's perfect for RVs, off-grid setups, campers, and home storage. 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.

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? There have been reports of lithium batteries producing too much heat and burning wiring harnesses for electric outboard motors. l just want to know if this battery has any measures to avoid such a scenario.

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.

REVIEWS

If your have Li Time LiFePo4 battery with bluetooth, read this.

I got Watt Cycle 12v 120ah with bluetooth first then I got LiTime one. Both came with bluetooth but one came on and others was off. So when I got Li Time battery, I checked the voltage. It was 3.24v. I thought it was defective then I send email to technical support. Technical support (Summer) helped me to understand how it works. LiFePo4 batteries with Bluetooth are getting popular but its confusing unless the manual explain each detail. So they ship with bluetooth off (3v ~ 4V). So you need to charge the battery first, get app on your phone, then turn the batterys Bluetooth on with app. Then you see the battery has 13v. (If not then go to "Manage and Control battery" page and turn the Discharge switch" on.) After that everything was ok.

- At 2025/02, Quick Start Guide doesnt explain about using App to turn on "the Discharge Switch". But YouTube does.
Also my app for iPhone hidden the 3 line at bottom (control icon) behind the orange bar and I can see only 1 line. (Thats the control icon you need to click to go to the page to turn the Discharge switch on or off. My LiTime app version is v1.3.5). - Look for Li Time app on YouTube -
I wish the app shows each battery cells voltage.

If you don't have knowledge about batteries enough, or you dont know how to handle Lithium-ion (Li-ion) batteries, Goal Zeros or Jackerys Portable Power Station maybe a good choice. But if you can handle them, they are a lot cheaper than Portable Power Station and better for long time to use. (Battery it self is small but with charger, power converter and cables, they are not portable. But good for the solar system or back up for blackout at home use ). I highly recommend Battery (BMS) with bluetooth.
Li Times battery seems to be great so far and they have great technical support.

I love the lighter weight of the battery. I no longer need to call on my trusty neighbors to help me install the battery inside my VW Bus.

Paul Muller

Shipping was extremely fast ( received within two days after placing order). Batteries work like a charm for our camper.

[KellG]

For the performance & reliability, I do recommend this battery

Dan M

The amount of power that this battery can instantly dump into the cart is awesome.

Used my new LiTime 12v 200a batteries for the first time this weekend. Couldn’t be happier!

After many months of debate, I finally bit the bullet and rebuilt my Stealth 4x4 cart with the new batteries.

Customer

So far for my golf cart it's been a great battery I got the 10amp charger also no problems.

Eve Ford

Great customer service! The batteries ran our solar system on our camper with no problem.

Klaus Feldmeier

The replacement was straight forward - the new LiTimes batteries are nearly 50% lighter than the lead acid batteries.

Scott Winebarger

No complaints yet, still building my system, so far, I am impressed

[Timothy Vaughan] Vaughan

Already had my 100ah trolling motor battery out several times and it’s delivered in spades. Very happy with my purchase!

John Hogan

Though I had to reconfigure the base of the robot, I have more than enough battery capacity to run for hours.

Perry Mahnke

It's amazing how much lighter the LiTime Mini batteries are, the conversion was easy, and the fit & finish on the LiTime Minis is great.

Anthony Carita

Love how light this battery is. My mower lost about 100 Lbs of weight. The battery has a nice case and looks top quality.

Rob D.

Great Products. Really Great Support.
