June 3, 20233 yr Someone has shown me a bunch of used lithium batteries ( NARADA NPFC 48 100 ) how can I test if they are in good condition ? I tested one of them and it gave me about 4200w to 4500w I wan't sure about it, How can I know it's approximate life span or it's cycles, I can open the battery and see each cell ( I used the multimeter they were between 3.24v and 3.4v after fully charging it and using it for about an hour on 250w ) Edited June 3, 20233 yr by Taher Sylla
June 3, 20233 yr https://solar-assistant.io/shop/products/narada You could use solar assistant and connect to the battery directly for that information. Although I would be very careful with who I buy any second hand battery from.

I think I can make a cable for it, no problems, but I need the solar assistant app, In syria we can't buy such things, although it would be very useful for our company!
June 3, 20233 yr You can use any raspberry pi locally , then buy just the solar assistant software and install on the pi. Check solar assistant website for further details on how to do so
