Afternoon folks. Thought I would post up a pack I am building for our van to replace a 510AH lead pack that's about done. Its nominal 12V with 8x 280Ah cells.

I recently took delivery of a sea eagle tandem inflatable kayak. Its got a good weight capacity, so we are considering doing a couple multiday outings on larger lakes.
I am considering putting a ~300W motor on it. I would never exceed 100W continuous though.
Any suggestions on cells for a...

The cells were over 5V the next morning.
I had him pull the cells down to 3.6V right away.
They went...
