In Netherlands we will group buy 37Ah NMC Pouch cells.

decrease our cost.

@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 :)
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 ?
In Netherlands we have SBMS0 , DSSR other parts + 500A shunts + B Grade pouch Lifepo4 cells of A123 Systems.
Please check price for SBMS0 here. For Lifepo4 cells you can inform your quanity and delivery Zip code , we can work on best offer.

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 ?
@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...
It is not even PWM.
It is something different , i am not the expert for this but maybe somebody reads here is actual
Electrodacus users so they can explain.
But strategy is this : Dontdepend on MPPT hardware or PWM algorityhm , buy extra panel with that money.
Make modular BMS andJust depend...
