Head to head
LiTime 12V 100Ah LiFePO4 against its price neighbours
The lithium batterys just below and just above it in price, spec by spec. Greyed rows are the same on both.
Built for trolling motors: a 100 amp BMS in a 60 amp hour pack, Bluetooth so you can see the charge on your phone, and cold weather charge protection.
A half size pack for kayaks, canoes and small boats: a morning of transom motor or several days of fish finder, with Dakota’s 11-year warranty.
Who it fits
Where the LiTime 12V 100Ah LiFePO4 fits in Tennessee
12 volt trolling motors and electronics on any boat; the value pick.
Capacity is run time. A 55-pound motor pulls around 50 amps at full speed and 10 to 20 at fishing speed, so a 100 amp hour battery gives a full day of ledge fishing and a 50 amp hour gives a morning. For a fish finder alone, a small 12 volt 10 to 20 amp hour battery is plenty.
The battery management system matters as much as the cells. Look for a continuous discharge rating above what the motor draws (100 amps covers any 12 volt motor), low temperature charge protection for January crappie trips, and Bluetooth monitoring if you want to see the charge from the deck.
