Hi,
I'm having trouble with my LiFEPO4 setup. Can you help me about diagnostic?
I have 2x pack of LiFEPO4 48v/20A. Each pack have "pouch" cell of 20A each. These packs were purchased at eCity. Packs are connected together to give a total of 48v/40A.
This summer, both chargers stopped working during a charge. Haven't noticed that the chargers died, I went on a ride thinking I had a full charge.. until all system shutdown.
Then, I purchased 2 chargers from PING (detail below). But when I connect them to the battery packs, both charger's lights stay green, and one of them start smoking after 2 minutes.. I disconnected them before everything goes on fire.
When I try to start the controller, the CA start briefly, showing 26.x volts, then shutdown.
So, From there, I don't know what to do.. is this my LiFEPO4's cells that doesn't work? Or the BMS? .. or my chargers? Controller? Did I purchased the right chargers for my packs? .. well, I'm stuck.. pretty well indeed..
What do you think?
