Hello to everyone!
I am a total newbie to lifepo4 batteries so I need some clarification. I read many posts on this forum and beyond but I am still a bit confused and uncertain about the ideal charging parameters for my setup.
I have following solar setup:
23.6V 20.7W poly solar panel,
Mppt charge module SD30CRMA-18V (I've tested 92% efficiency with 1A max charge current and 96% below 1A. 1A enough and good since below 0.2cc of my 6Ah battery),
New 4 x 6Ah 32650 batteries in series,
Bms bw-4s-S30A with balancer,
Electric energy tester
Total cost about 28usd.
I use it to charge the battery during the day (no loads)in order to power led lights and charge 5V usb applications during the night time.
So my question is following, since i have to manually set the battery voltage (eg the voltage where it stops charging the battery I suppose!? )
on this simple charge controller module, which Volt parameter should I use in order to charge the battery to about 90% and then stop? I want to get maximum life cycles out of this battery pack. Would 14V be ideal or do I need to go higher?
Much appreciate if you could kindly also explain also your ideal charging voltage suggestion so that I learn something!
