I had this type of thing happen to me. I was making some busbars for a 4S2P CALB 180 battery. I was using a short wrench and I was cupping it in my hand so the wrench wouldn't make contact. Well my carbide ring touched the wrench and one of the terminals. It was only 6.4 volts, but in a...

You know we're terrible -- you know the few that would check this thread to see how bad he damaged a cell or two --- Good job backing off and waiting on a BMS -- I always just Parallel them up and wait

I'll stay tuned to hear what happens --- Hopefully not what has happened to so many others -- one cell going way over 3.65v and you're looking for a single cell --- Good Luck

Yep those Suckers are a pain in the butt -- I keep several propane tanks filled -- I make sure I put tape over the valves "Now " after they caused me problems

If you have those cells with the shallow threads, I wouldn't use those nuts. It takes a little bit of force to push the stud through that nylon (you're basically threading the nylon as you go through it ) Just use standard nuts with a lock washer and flat washer . Then torque

OK -- Now that you have us all hanging here --- How does it run/ride --- Any more Magic Smoke -- Hopefully no Red Liquid ( blood )

One big problem is -- Cheap Chinese cells with minimal protection -- another thing is -- Heat and Cold charging / discharging -- But for these application Li-ion is not a good choice

Looks Awesome -- Dude that's one Organized Garage -- More Impressive

I would of moved my truck --- He's lucky that didn't end up worse than it did -- Fuel Tank Etc I find today people are more interested in getting it on video than Safety

When ever I set post --- I always hang my post where the concrete goes underneath the bottom of the post-- Over time if you don't do this ,they'll sink right through the concrete -- Since you're using steel post, you can also run a rod through the base of your post

Nice Job --- Dude you're making me want to find a Golf Cart to rebuild--- My wife might shoot me though -- I already have Hot Rodded scooters for the Grandkids (the one that does 28mph sure is fun though)

Looks like he's been busy (y)

And a Fire Extinguisher mounted on the handle bars -- JK :oops: I would discard any cells that look like they were close to the heat

One of the main problems with the OPs packs --- The cells he used ,No matter if they were Brand New out of the factory to his door step --They were not the right type of cells --- Laptop and Modem cells are not designed for High Amp output --- But on the other hand I see no problem with using...
