Flat out question since it seems to me I will be needing to buy a variable power source to balance my cells B4 my build. (thanks to all for the responses on the US high quality sources to avoid this, but I can't afford what I'd hoped in buying pre-matched cells here in the us).
Instead, 280ah Eve/Lishen cells were just ordered from Will's Aliexpress link. Overkills 120A 4S BMS is on hand already as well.
So I have a unit like this coming for the prebuild top balancing: https://www.ebay.com/itm/Dc-Power-S...575549?hash=item1cfff8bc7d:g:L~wAAOSw8UNgFvrN
This leaves me to question if I can charge the battery after it is built using this supply directly relying on the BMS for the correct charge profile and shut off?
Or, Since I do hope to upgrade from the crap PWM that came with my suitcase 120w panels to even more portable panels later, can a properly sized MPPT be used to mutli-stage charge the battery using the power supply when AC is available rather than buying a dedicated LFP charger at around the 30a this power supply can offer?
Does this even work?
