FAQ

What is the ideal thrust range for a 36V 50Ah trolling motor battery?

100-120 lbs trolling motor

Can I use the trolling motor battery in my electric outboard motor?

Normally, it's not recommended to use a battery designed for a trolling motor in an electric outboard motor since the surge discharge current might not be sufficient. Outboard motors often require higher power for acceleration and sustained operation, which can lead to higher surge currents that trolling motor batteries may not handle well.

If you’re planning to use an electric outboard motor, it’s best to invest in a battery specifically designed for such applications like LiTime Outboard Motor Batteries. These batteries are built to handle the high power requirements and ensure optimal performance and safety.

Read on Electric Outboad Motor VS Trolling Motor for more detailed information.

Can I connect the battery in series or parallel?

LiTime 36V 50Ah lithium battery supports connecting up to 4 identical batteries in parallel for up to 36V(38.4V)200Ah battery system. However, the battery do not support connect in series.

To connect in series or parallel, batteries should meet the below conditions:

identical batteries with the same battery capacity (Ah) and BMS (A);
from the same brand (as lithium battery from different brands has their special BMS);
purchased in near time (within one month).

Can I charge LiTime 36V 50Ah TM LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

LiTime 36V 50Ah TM LiFePO4 batteries can charge between 0℃ to 50℃ / 32℉ to 122℉. The 36V 50Ah TM version has low-temperature charging protection function, it would cut off charging when it's below 0℃. It's recommended to charge the battery indoor during cold days.
