Hi Craig, Criagmck has a couple of lightly used Chargery BMS he wants to sell, but he doesn't have the relays. Is there a relay you would suggest that I could get quick here in the US? I am actually hesitant to go with the Chargery after watching Will's video on it....but it looks like that is the only way I am going to get something quick enough to get my system up and running.
