Chinese batterys plus other expensive bits needs ordering.

I wonder if splitting the modules (2 parallel, then 2 series) into individual cells is an option? Then join them up series to make 12V

if each module is 7.6V nominal, 8.4 Charged, how can you get to 12V? are there 4 x 3.6/4.2V cells in a module?

From the ad it sounded like they were in a mixture of parallel and series, I didn't do the maths but figured they would be standard voltage.

7 modules in parallel for a 48V bank apparently

i didn’t understand exactly what the guy was saying (what’s new. ) but there was something about if instead of the modules he bought the replacement pack it would be simpler to step down ? to what he required for his installation given that lighting aside he was planning on some form of inverter

There has been some talk about end of life EV batteries being reused for offline solar energy storage on the grid. This is apparently more environmentally friendly than recycling them.

Seems a good idea to me ...
