Just thought I'd share my shiny new 460AHr, 2p4s LiFePO4 battery bank:
Each pair of cells is paralleled using the bus bars that shipped with the cells, and each cell pair is chained to the next with two 2AWG jumpers. In turn, the class T fuse connects to the bank with equal length parallel wires, as will the BMS shunt.
Cells are in light compression, plywood battery box is fiberglassed into the hull. Battery is tied down by 3 webbing straps, plus the end fixtures are connected to the box. Picture was taken while setting up a REC ABMS, most of the time a plexiglass cover will be screwed down on top. The batteries themselves are sitting on plastic pool deck tile to allow any moisture that gets into the box to drain out the bottom.
Being a small boat (27' sailboat), it's a pain in the ass working on anything, but it's definitely going to be nice when it's all said and done.
