LiPo Battery Discharge Time for Storage

[jbilby62]

Hey everyone,

I've been noticing on my 4S 6700 mah traxxas LiPo that the discharge time when I put the battery in storage mode can take up to 2 hours. Is this normal? I have not had to charge it back up to storage in the last few runs but I don't remember it ever taking that long when I do need to charge it back up to storage. I am using the traxxas 4s ez peak live charger too.

Thank you!

Most chargers can only discharge at low power because they literally have to burn off the extra energy from the battery. Aka turn it into heat.

And turning a lot of it into heat quickly would overheat some components and release the magic white smoke from the charger.

There are ways around this.

What nino said. Chargers use their discharge circuit for discharging, which most chargers have around a 1A discharge circuit. So you will discharge at that lower rate, whatever that is for your charger. The Hota D6 Pro has a .1A to 3A circuit.

If your charger supported external discharging (not sure if it does, but I doubt it), you could discharge into a resistor, or another battery at a much faster rate.

with 665 mah discharge rate your lucky it just takes 2 hours.

Oh wow lol

I like the lol. is that still happening... facts are facts. specs r specs.

Thank you for the information guys! I just wanted to make sure that the cells were not degraded or had any other potential issues that would screw the discharging of the battery up. With a 665 mah current discharge, it makes sense why it takes so long.

It's just that I actually laughed when I saw the specs you posted. That's pretty terrible. By the way tnt, what charger do you use?

Mine can take more than ten hours.

I have a bc 8A it will charge 8- 6 cells thru balance wire at 8 amps. I was given a toolkit 8 to test but my Schultze 2514 is my go to charger925 amp 14 cells adjustable balance to 5 amp) it was a custom build b4 the went by by. I have reactors from 1/2 amp to 30 amps to discharge battery buzzer added. for 2+ cells I have a discharge block..

I have seen some of the Toolkit stuff. They have some snazzy little chargers for on the go and such. Not really useful for me. But I really wouldn't mind having some of their test equipment, and that cute little power station they have.

What is a BC 8A?
