So I purchased 64 new LF304 cells from Alibaba: https://evebatteryglobal.en.alibaba.com/product/62430842455-926611901/
However I somehow failed to notice/realize what Oliver Li Meant when they said it has M2 laser Positioning hole. I'm not trying to figure out how to actually hook these up.
My goal is to make 3 48v packs and 2 24v packs.
Having read other posts here I have seen people suggest tig welding the terminals on ones that broke off but I have not seen anything indicating anyone actually did this.
The other option I can think of is drilling 6mm into the top with a 5mm bit then tapping it with a M6 tap, I asked the seller about drilling into the top and this was their response:
We suggest using laser welding
It's risky.
if you do 6mm, it might will cause some bad thing.
I have mig and stick welding experience and am planning to get a tig welder anyway but I also have a drill press so I could drill the terminals.
Since the cells have the m2 laser hole I would not have to worry about centering the drill bit.
Do anyone have some advise/suggestions?
I still need to inspect the cells to see if they meet their specifications, I have only opened one box so far and all the cells were from February 2023 but different days and sequences. they don't have the grade B marking on the QR code but I need to peel off the top to see if they were given new QR codes.
I'm located in Central NY(Central NY state, not New York City) if anyone knows of places that might be able to help.
Thank you
