How to Choose Your Electric Outboard Battery

We've ranked the top factors based on real user needs. Use this guide to find the perfect fit for your boat.

8 Key Points to Consider

Boat Size & Weight

Determines the required battery capacity for enough runtime.

Usage Scenario

Lake fishing needs steady power; ocean cruising needs saltwater resistance.

Runtime & Capacity

Calculate runtime by motor draw (e.g., 100Ah gives ~5 hours at 20A).

Voltage Compatibility

Must match your outboard (12V, 24V, 48V, 60V, 72V).

Budget

Balance cost with longevity (lithium lasts 5x longer than lead-acid).

Battery Capacity & Type

LiFePO4 is 50% lighter than lead-acid with BMS safety.

Installation & Maintenance

Easy setup matters. Waterproof, drop-in ready; 5-year warranty.

Reliability & Safety

Avoid breakdowns with power-saving modes and robust safety features.

Top Picks for Electric Outboard Batteries

Power your boat with LiTime’s most trusted lithium batteries, loved by boaters for their reliability, lightweight design, and long-lasting performance.

This battery charges fast and lasts a long time for my outboard motor. The Bluetooth feature is a game-changer for keeping track of the battery's charge.

Scott Cutler

My pontoon boat used 10 6v deep cycle lead acid batteries plus a 12v accessory battery. They weighted over 600 pounds not including the extra batter in the front to help balance the boat. Thanks to the sealed batteries, I was able to replace all batteries with 6 OBM Lithium Marine batteries for greater than 500 pound less weight. As I could mount these batteries closer, I was able to keep the batteries close together in an inside compartment right next to the main 60V elecric outboard motor. This made a better connection. The bottom line is that I get better performance with a 500 pound decrease in boat weight. I also appreciate the bluetooth connectivity for each battery so I can see how the batteries are performing. It was a great decision to make this change.

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.

Are LiTime outboard motor batteries 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.

Will this battery avoid supplying too much voltage, current, or heat to the motor?

All LiTime batteries, including outboard motor batteries, are provide 5 basic BMS protections: overheat, overcurrent, overcharge, overdischarge, and short circuit protections.

More than that, with LiTime newly upgraded BMS, the outboard morot batteries 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 to charge the LiTime LiFePO4 lithium marine batteries?

Because LiFePO4 lithium batteries have different charging requirements than lead-acid batteries, we recommend using a LiFePO4 lithium battery charger.

Here are the charging options for LiTime lithium marine batteries:

1. AC-DC Lithium Battery Charger: Select a charger with the appropriate voltage to safely charge the battery.

2. Solar Panels: When using solar panels, always connect a solar charge controller to ensure safe charging.

3. Alternator/Generator:

DC Output: If your alternator or generator provides DC output, you will need a DC-to-DC charger to connect the battery.
AC Output: If it provides AC output, use a compatible battery charger as specified in the product manual to safely connect the battery and generator.

What's the warranty of the LiTime lithium marine outboard motor batteries?

LiTime offers a 5-year warranty on our batteries. For more details, please visit LiTime warranty policy.
