Very true. I plan to build a house here in a few years and with that about a 40x60 shop. That way I have room for my various projects and if it burns down, it sure won’t be attached to the house.
are you even using a BMS (battery management system) ????? never and I mean NEVER mix up random cells together and make a pack like that with em, you're lucky it didn't burnt down your house also keeping a big bucket of sand (pour on the cells incase of fire) and doing multiple test charges before actually using the pack would be a good idea.
I did not use a bms on that pack as it was all salvaged cells, which is also why I didn’t do fuses like my other video. I have also done the rest of my packs with bms or bms leads w a smart charger. They we all soldered w strips and essentially a bomb, which is why they went in an ammo can. I’m working on property so I can build a house and a shop so if there is a fire it’s just the shop. Hard to make money on 170 subs though lol. Sand would have been handy if not being in a steel latched can. Mixing the cells, they were all tested and assembled using repackr.org. So I guess you could say that it was a purpose built pack but w out a whole lot of safety built in, I knew this going in as well. Thanks for the feedback.
" essentially a bomb" well yes it was a bomb indeed and by mixing random cells (not talking about the grey ones) you can do it but only like for powerwalls/power banks but fused ofc as they are not necessarely the same capacity or have the same discharge/charge rate. Using fish paper rings for the + side is pretty much required for safety. Shrink wrapping, padding with heat resistant foam, insulating with kepton tape (non conductive and heat resistant tape) using a bms for charging, discharge is ok without a bms as long you don't go below the minimum voltage recommanded for you battery type. otherwise goodluck with your projects, be safe.

Check your battery before you build it and make sure heat srank it and check the wires and have bmx
It could have been much worse, at least the house didn't burn down, nore did it trash the bike.
