Hi Folks
I've just recently put a new DIY LiFePO4 battery into my campervan. I used 200ah Winston battery cells with the 123 Smart BMS.
I'm trying to charge the battery with a combination of:
1) Votronics VCC 1212-90 battery to battery charger
2) Epever XTRA4210N MPPT solar charge controller
The battery to battery charger and solar charge controller do not charge the battery at all, although they are both receiving the correct input.
The battery to battery charger is getting current from the alternator and it starts up (fan spinning, etc..), starts outputting current to the LiFePO4 battery and then after about 5 seconds it turns off for a few seconds and then starts the process again. It keeps doing this indefinitely and never charges consistently.
The solar charger receives input from the panels and outputs it to the battery, but the BMS does not report any charge from the solar charge controller.
Does anyone know why they'd be doing this? Is it possible that the BMS is disconnecting the charge?
