Compact smart lithium power
640Wh and Bluetooth monitoring in a 14 lb battery.
The Epoch 12V 50Ah Essential Series battery fits trolling motors, fish finders, compact marine electronics and small off-grid loads that do not need a full 100Ah pack. Bluetooth monitoring, a 50A BMS and flexible series/parallel options make it more capable than its size suggests.

Confirm before ordering
Fit the entire system—not only the headline spec

Common questions
Is 50Ah enough for a trolling motor?
It depends on motor draw, speed setting, wind, current and desired runtime. Compare the motor's real amperage with the battery's 50A continuous limit and 640Wh energy.
Does it have internal heat?
No internal heating is listed. The BMS protects against unsafe temperatures, but charge only within the approved range.
How many can be connected together?
Epoch's definitive specification table lists up to four matched batteries in series and four in parallel. Follow the latest manual before building a bank.
Can it start an outboard motor?
No cranking rating is published. Use it for compatible deep-cycle loads, not engine starting.
