Just for the record, we are using a 15000 watt battery pack that weighs
828 lbs. Add to that the battery cable, 2/0 welding cable, the charger,
this is a plug in, Controllers etc.

With battery technology what it is today we are lucky to push a nice
little light weight hull like ours as much as we can. The future however
is looking brighter for much better batteries with higher capacity and
much less weight.

Where is the high capacity battery technology heading? The last major
advancement I am aware of was the development of lithium ion technology but
you don't see many of those in really big battery applications. Lithium can
also be a bit dicy in terms of handling (or getting wet) if I recall
correctly.

Seems like we are still stuck in the lead/acid age, either in wet cell or
AGM configurations despite many years of forecasts predicting major
technological breakthroughs in battery construction.
