[QUOTE=ksquared;1693804]I purchased 700ah batteries from Balqon, and also got their BMS.
However, I don't see much information at all about it anywhere, and of course no user manual from Balqon.QUOTE]
Balqon - as any relatively young and emerging company - basically assembles LiFePO4
batteries with Chinese cells and Clean Power Auto
, adding commonly available fuse and Gigavac (or Tyco) coil contactor. Recently they published a PDF brochure explaining the basics of assumingly their Qanbuss
BMS, which appears to be more suitable for huge banks of LiFePO4
sandwiches installed on electric
vehicles. I don't know what are the advantages of Qanbuss BMS in comparison to well established Clean Power Auto systems. And - of course - by definition the brochure is not the manual...
With a bit of DIY skills it is perfectly possible to assembly identical LiFePO4 sandwich and save a lot. I just did that, purchasing
cells and BMS from various US suppliers. As for monitoring I'm using popular NASA Clipper BM-1 display, although it is more for fun than necessary since BMS does the job of maintaining the battery health
