Re: LA versus lithium battery sizing
Sorry Rick. Even in the armchair, there are clues to BMS systems. A single volt sensor across a pack of cells, is the barest low end BMS no matter what the salesman says. And while Li doesn't care ab…0 · -
Re: LA versus lithium battery sizing
Alligator clips on tarnished bus bars are not functional connections for a BMS. And it's not a BMS except in the sales pitch. That's a battery voltage monitor with hi & lo cutoffs (maybe both if …0 · -
Re: Morningstar TS-MPPT-60 Controller
If you have 6 PV panels, and are charging a 12V battery, the most efficient condition is to use 2 panels in a string, and 3 strings paralleled at the combiner. ( ~50Voc, 29A ) 1200 watts @ 12V is too…0 · -
