Lipo problems - 1 of 3 cells rapidly discharging

[James A]

Okay, here's one that I think I know the answer for but am not sure. One of my 3 cell packs has been suffering after having had a break for a couple of months over the winter.

Anyway in short it appears to charge without issue but the voltage drops below 9.6v for the pack almost as soon as I have my 450 in the air. I then check it when I get home and the voltages look normal.

I have just run it through a power cycle and can clearly see that one cell is discharging far faster than the others and then appears to be rebalancing itself once the discharge has stopped.

I'm assuming that I simply call it a day with this Lipo as the offending cell must be defective but thought I'd check in case someone new something I didn't. Also what do you do with Lipos that you want to get rid of?

All help appreciated

Hello, anyone got any advice...... even if it's only the proper way to dispose of them

[vinny155]

stick it in a bucket of salt water is whats been reccomended before,not sure if its a case of just chuck it in there or not,i think id use a pickaxe through it

I usually either charge it with a nicad charger, shoot it with a shot gun or air rifle. Or short it out. All of there disposal options make you smile the most. Nicad charger is my favorite. Maybe its the 5 year old in me but a bucket of water is sooo boring. Physics rock !!!

Well I could try the air rifle ...... but that's another post

When a cell goes bad there is no way back mate, i just destroy it in the most amusing way possible so i get a bit more moneys worth. (dont do it while your washing is on the line the smoke stinks)
