Suggest perhaps making it so only OP can resurrect an old thread?

If you over-charge a lithium chemistry battery, it will explode. They cannot dissipate excess charge as heat.

Commander Keen's ray gun? Great little project!

Ice cube trays work a treat. Just make sure your screwdriver is magnetic, so you can pick up the screws. Then if you need to put the job away, you can simply pack the whole tray up. edit: The main purpose, is that I organize parts either or the order that I removed them, or in positions...

I would defiantly remove the shrink and see what is going on. I would consider using clear shrink when re-wrapping so you can observe if there is a leak. With all lithium batteries, I subscribe to the 'if in doubt, throw it out' policy.

There are a few disadvantages. Wood has a tendency to crack. Wood can absorb moisture, and if the voltage is high enough, arcs can cause wood to burn, leaving a more conductive path behind. Building pack holders, or shelves for batteries out of wood makes sense, if you find it easier to work...

I personally wouldn't flash the BIOS. You will void your warranty. Instead, do some mining benchmarks, and use something like MSI afterburner, to downclock the card till you find your sweet spot. Using an amp clamp on the PCI-E power connector is a good way to measure power consumption. Then if...

Photos? Perhaps a fake?

Mixing cells in high drain packs is not ideal. You will need to match capacity and internal resistance as closely as possible. This is more for the sake of the cells, than the sake of your safety.

There is the ZB2L3 if you want to go the DIY route. It is also has a 3a maximum load. Another place to look is Google USB load tester. According to some YouTube reviews some of them are quite good.

This is an interesting possibility. Given that the cell vented from the side and not from the top. Even the fact that it caught fire in the first place. It really should not be possible if the cell is fitted with proper protection.

Defiantly worth contacting your local scrap yard. Or ask your local sparky. Sometimes they will sell you some off-cuts for pretty much scrap price.

Personally, I would remove a couple of cells, and test them first. Charge them slowly, capacity test them, then cycle them a few times. Check for self discharge. Having no experience with these batteries, I don't know if this is possible without dismantling the whole thing. In which case you...
