Deyan Vitanov Posted April 17, 2022 Posted April 17, 2022 So as I spent a lot of money for my Pylontech US3000C batteries, I was thinking: is it possible to find a Pylontech BMS and connect it DIY LiFePO4 cells with the idea to expand my storage at low cost? I have some new LiFePO4 chinese cells that I want to hook up. I could not find any Pylontech BMS board over the internet. I guess this is possible if I set my Growatt inverters to US2 battery mode (custom charge/discharge mode) but I really want to keep the communication between the Pylontech BMS's and my Growatt inverters. I believe this is the future as individual cells always well be way cheaper than pre-build modules and in 3-4 years we will have plenty of cheap options to upgrade our high cost existing systems.

And in that case it is cheaper to import complete batteries. You won't find a Pylontech BMS... Quote

I've always been of the opinion that the Pylontech .5c rate is for longevity. Nexuss 1 Quote
