Need to drain a 272ah lifepo4 battery cell

Just a very very quick test this morning before work, and I mean like 30 seconds. Nothing bad happened, it charged as it should for that short time, will try properly later.

I spoke too soon, well maybe not because of that though. I took it off a single cell and connected it to a series of 8 cells to charge them all, but I forgot to adjust the voltage from 3.65 to.. higher before doing so, and it let out a little magic smoke and now only kind of works. Maybe it's because of the inverter powering it or maybe it's because chinesium.
