Ultralite Lithium Trolling Batteries  12V, 24V, 36V, 48V

The Most power, in the Smallest package, that is extremely lightweight,  lasts a Long time, for the best price.

Seaquest Battery offers a variety of Lithium Marine Trolling Batteries Custom Built from 24V to 48V for your Tender, DInghy, Bass boat, Jon Boat, Submarine... you name it.

Seaquest batteries uses a modular system.... What that means is we don't put them in series because they wont balance during charging. No other batteries will either contrary to their claims they will.

Be advised all other lithium batteries have a balancing current of only 50 - 100 milliamps !  Deep cycle batteries need  high rate balancing.  ( Seaquest batteries have a 2A balancing capability )

If you want more Ah than one battery can give, then, just put a 2nd battery in parallel.

NOTE; be advised that putting lithium batteries in series or parallel also have drawbacks of performance fading due to  variations in branch currents. https://www.sciencedirect.com/science/article/abs/pii/S0378775316301951.

Experiments and modeling results demonstrate that, when lithium cells are connected in series or parallel and cycled at high rates with high amp chargers, a 20% difference in cell internal resistance between multiple cells can lead to approximately 40% reduction in cycle life when compared to cells parallel-connected with very similar internal resistance/impedance. This internal resistance mismatch leads to high current into each cell during part of the charging cycle. High currents will lead to substantially accelerated capacity fade in your batteries and substantially reduced life cycles.

Seaquest suggests using a larger voltage single battery vs multiple smaller 12V batteries in series.

All Seaquest batteries come with 8 year pro-rated warranty.
