    Insulating the base of aluminium cased cells

    Given that the aluminium case is positively charged and the base has no plastic covering I'm wondering what precautions people are taking with electrical insulating. I'm using them on my boat where damp can be a bit of a problem. I'm putting a 0.5mm sheet of fibreglass between the cells and any...

Can I simply do this by introducing a bit of voltage drop through either reduced cross section or longer cables? It's a 20amp charger for 270ah LFP...

I'd like to be able to switch the charging current from my solar bus between a LFP house bank over to an AGM start battery when the LFP is at my chosen max state of charge level. (Part of the reason for this...
