Okay, things were going pretty well (Testing my used Leaf batteries) at 7.4v (3.7v x 2s) each, one at a time.I am planing on making packs of 7 batteries apiece to create 14s2p?
Well it takes 4.75 to 6 hours to top off each battery to 8.4vat 4amp. Startingor Shippingvoltage was 7.88 to 8.01v.
Once i create this 48v battery I am looking for ways of charging it so it doesn't take (7 batteries x 5 Hours) 35 Hours. I am planing on putting each pack under an expected load for a while to ensure it functions safely before tying all 6 packs together in parallel.I would also like the ability to charge pack to 4v per cell to equal 56v actual for temporary storage until solar panels-chargers-inverters are installed this spring via 110-120v outlet here in the US after bench testing is completed.(I Hope).
Currently i have a simple ISDT and Imax b6 chargers (48v or 14s is not an option). So obviously i amin the market for something useful and efficient. Any and all simple DIY, or Commercial chargers and ideasare welcome.
I am choosing to build this power wall somewhat like a cartridge style wall due to financial and availability (of 18650)issues. So i would also like to use the same AC Benchcharger (If Possible) to also charge a 14sXXP 18650 pack in the future.
I get the feeling i'm asking for a golden Unicorn but hopefully i am wrong. If i am going about this all wrong please do not hesitate to correct and help.
This same Golden Unicorn can be used to help equal Voltage of packs taken out for repairs and or adding new packs to the existing power wall later.
