Wash your hands/face/body, get the baking soda, THEN grab your camera so we all can see!

Are those cells bone dry!?!?!? Wow, that is what heck of a boom. Did you have to tow it home, or did you just bypass the battery and continue?

Yes, big boom. Tow Geo and tow rope to get it home. I think I'll put the alum battery back in to replace the exploded one.... |

Wow. What do you think happened?
Cell reversal & overheating?

Yeah, I'll go with that.....
I was really pushing my luck with that battery as it was and am not at all surprised it happened. I am actually pretty lucky that the one I converted to alum didn't do that before the conversion: it was showing way too low a voltage after commute as well. This gives me even more incentive to relocate the 2 batteries in the trunk outside passenger compartment. |

My car uses gel cells that are inside the passenger compartment, but sunk below the back seat. (Where the gas tank was.)
That is then covered with 3/4" plywood with carpet over that.
The one time I accidentaly shorted 144V, I was glad that there was that chunk of plywood between me and the battery terminal.

Wow. Well, before I got the battery pack monitor, I reversed cells in a couple of batteries (2 or maybe 3).
When reversal happens, I believe you're effectively charging that cell at whatever amperage you're drawing from the pack at the moment. (For me, that could be anywhere from typically 75-200+ amps!) Which means that battery is going to get awfully warm, awfully quick plus it'll likely be gassing like crazy and building pressure in the case. POW! :O
