Charging LifePO4 batteries

[Bill 112]

I just ordered 2 SOK LifePO4 batteries.. I need a MPPT Charger for them. I saw Will on a you tube video with a

EPEVER MPPT Solar Charge Controller 40A 150V charger​

I was looking on Amazon about buying however....it lists all the batteries it will charge but it doesn't list lithium. It does say user settings. Does anyone know
if that is where you would have to set individual lithium battery charging info....for the charger.

Yes, under 'User' you can set all the custom values for lithium...

Will recommends that you get the mt50 controller with the epever because it is difficult to program without it. If you search the forums, multiple people have discussed the settings needed.

i tried these settings and i get "parameter error". i'm running 4 12v 170ah LiFe PO4 batteries from bigbattery.com in parallel.

Equalize voltage has to be high-than or equal-to boost voltage with Epever.
