Discharging lipos

Why so low? I mean you discharge them in your vehicle at way higher than 1C. Just curious.

Anyway, I usually just discharge them by running them in my vehicle, then charge them up to half the capacity. So, if they are 5Ah packs, I put 2.5Ah back into them. If this is not feasible, then I just discharge them via a resistor load until they get to ~3.7v/cell under load. Once I remove the load, they usually rebound back up to ~3.8v/cell. Of course, I have to watch this process, but I'm usually at my bench anyway...

SInce it is inherently damgerous to allow Lipos to go below 3.7V why would you need to discharge them anyway. I would think storing them at full capacity would be a better method so they will not fall below the required 3.7v level whether you store them for one month or 12 months. As long as you store them in a good fireproof container you should be good to go.

3v per cell, not 3.7v Jerry.....

Yea I know James. That is what I meant. I am just saying why discharge Lipo's at all for storage? Especially if you do not know for sure when you might use them again. Just charge them up, and lock them away.
