All,
Wanted to post up my 14s 48v lithium battery conversion and see what everyone thought. Its a 150ah 14s pack, or ~8kW battery, with about 5-6kW of usable energy.
Prepping the old wiring (meaning ripping out the crap the previous owner had hacked / sliced together)
First view of how I plan to wire up the BMS. I went with a Chargery BMS 16t which will handle the balancing and charge/discharge mains. It can balance at 1.2a which is great considering this is a 150ah pack. Also has a nice screen to show SOC and turn on/off the pack.
Yay, batteries! Did some size up of how the box would look.
Some disection of the pack and my plan for cooling / heating. The packs have resistive heaters on the outside by design so that will be used when I take this ice fishing to keep the pack happy.
