Install Tesla battery modules #8

Closed kklem0 closed 4 years ago

Install Tesla battery modules under the beds in the sleeping room.

Idea is to have 8 battery modules, 2 in series x 4 parallel, so we can have a 48v DC system. min 40v (need to double check), max 48.2v, 4.02v per cell.

Batrium just launched MultiMon 8, which makes it possible to parallel 15 12s. It's a slave of WatchMonPlus so we need to get 1 WatchMonPlus and 3 MM8 in our system. Cost of MM8 is 2,200 NOK. 😊 So for BMS the cost is 5,000 + (2,000 x 3) = 11,000 NOK. Almost half the price!

Works

Installed 2 modules, 6 will come next week but will open another issue for that as it will use MM8 instead of WM5.
