    Hi from the Netherlands

    @tafkaw That looks great inverter. I guess i still have a few Litekoola 500i testers. I am not salvaging cells anymore. I know it is important to test more cells/day. If you want you can borrow them for a few months. Free not Dutch style :)

    Hi from the Netherlands

    Welcome @tafkaw and Hallo from Utrecht. You salvaged 10.000cells but you still didnt make any Powerwalls yet ? I have 24V SBMS and 500 Lifepo4 cells on hand for sale. That inverter could handle 10.8kWp or you will use parallel Mppt chargers ? Good luck

    Charging voltage for LifePO4 4S pack?

    I made like you advised. Now my question is. Ming he set maximum 27.6V maximum. And this is very safe for Lifepo4/per cell 3.45V Max. But it will not cut charging. It will always give 27.6V even it is full. Is that so bad for batteries ?

    Charging voltage for LifePO4 4S pack?

    Solar. panel connecter to Ming He charge controller. Charge controller connected to Battery. Battery connected to Ebike battery poles. Is that what you mean ? @Redpacket

    Charging voltage for LifePO4 4S pack?

    For my case i dont have BMS. Ming He input solar panel ( or maybe an adaptor later ) output is battery. And battery directly connected to Ebike controller. No BMS. BMS at Ebike is almost always on its own battery. What do you think ?

    Charging voltage for LifePO4 4S pack?

    @jonyjoe505 will this buck converter or minghe 7210a will cause any problem at Lifepo4 in long term ? I tought Lifepo4 does not like to be under stress and likes to be not charged when it is full. My Lifepo4 pack is 8s 60Ah Pouch cells. This giant Ebike battery will be charged by a small 80W...
