Hello Everyone!
Let me begin by thanking all of you for posting your journey. I find countless hours of reading and I would like to think I am learning at a amazing clip thanks to you.
Forgive me if I have missed this posting somewhere.
I’m wanting to build a 24v 7s2p 18650 battery bank and I believe I’ve bought all of the right pieces still somehow I’m not having any luck.
Ive purchased 8 - 7S Power Wall Balanced PCB 18650 Battery Holders off of eBay. These are the double sided soldered PCB holders that connect with brass posts and a ribbon cable.
I also purchased a 60 amp BMS (3 x 20 amp
Bms units all soldered onto one board)
Additionally I purchased a State of Charge unit.
my plan was to purchase a few used 18650
Battery packs and then stock my PCBs with the salvaged 18650 I get from disassembling the used banks.
Everything was going to plan….pulled apart the used packs and i began populating the PCB holders. Once populated I began assembling the holders (installing and stacking them using the brass posts and the ribbon cables).
iI filled them up and installed the BMS unit and figured I was looking good.
This is when I ran into trouble. I’ve been trying to charge the assembled 24v 18650 PCB monster I made and I’m having no luck.
Am I over looking something. Do I need some special charger. The BMS and pcb units I purchased can be found here:
I was Under the impression that this be a mess unit and PCB holder set up would allow me too balance and charge all of my 18650s using the power input on the BMS….is this not the case?
I’ve bought two different lithium chargers and still I can’t get it to charge at all.
Any help
Would be greatly appreciated!
Thanks again guys,
Joshua from Oregon
