Thanks, that is a very educational reply. Does surface area play a role in the capacity to handle greater loads? I’m not sure if the...

Thanks, I’m learning as I go so good thing this post is in beginners corner 😀 These are the closest battery specs that I can estimate...

I have made a number of E-bike batteries - the nickle plate thickness is picked based on the max amperage per cell you will move. a...

It's a general purpose 12.8V 135Ah battery. Pics explain it better here I have a 1200W inverter that will be used occasionally but it...

Looking to spot weld nickel plate to connect these batteries as illustrated. This will be my 1st time spot welding (I will DIY build a...

I'd like to order nickel sheets to hopefully spot weld onto the terminals of this battery pack. Can anyone advise what thickness I...

Thanks for your message. I've heard that buying direct from Eve rather expensive for shipping small quantities. The quote I have for DAP...

EVE 304Ah currently sits at $78US before shipping directly from them (not that I really recommend getting them directly from them) -...

I made 1P16S from the same cells from the same store. I did not use the supplied bus bar and instead made flexible cables with the BMS...

I've been quoted 83-85USD (before shipping) from China for EVE 304AH Grade A cells. This seems like very attractive prices compared to...

G'day DIY brains trust. Long story short, I have a 135Ah - 12 V battery consisting of 32 33140 cells in a 4S8P configuration. The...

Anyone managed to solder these? What wattage iron did you use? I bought the version without the laser welded nickel. My $20+ spot welder...

Thanks. It's very late where I am and I needed some reassurance!

4S8P = 12V nominal

All cells are 3.2v 32 Batteries total 4 x 8 Aren't they all just connected in series?

Things I'd try at this point: 1) measure the voltage across the terminals of the cells them selves, both individually (no need to...

Batteries should never end up in a landfill.

HAHA -definitely short-circuit blues however I don't think all is lost. All cells appear to be fine, just the BMS is toast. Landfill...

All 32 cells measure 3.34V I took the heatsink off the BMS and a scorch mark is evident in the pad over one of the transistors. The...

So I did this. I went back to the supplier and figured I'd make them an offer on the dead 135 Ah battery and see If I can performer...
