Im shopping for new batteries, and im noticing "high discharge" and it made me think about discharging.

Ive never discharged, I only balance my lipo's and then store them charged. Should I be discharging my batteries each time or when I'm done for the day? Also, how should I store them?

Ideally, you should have the battery sitting somewhere around 7.4V for a 2S LiPo (3.7V per cell) when you store it. Some chargers have a storage mode on them that will discharge/charge as needed to get to that voltage. I've had fully charged batteries sitting around for a couple of days with no problems, but it's not something I'm making a habit of or storing them that way for any length of time.

Lipos dont like to left sitting fully charged, over time it raises the internal resistance of the cells


Charge them before use
Use them
Charge / Discharge them to 50% (3.85v / cell) when you finish


Cheers

Gotcha. Thanks for the info

I realise this isn't really your question , but I've always thought of the description "high discharge" as "the battery has the ability to be discharged at a high rate" (or discharged fast) in the vehicle or anywhere else. It has nothing to do with whether or not the pack should be discharged.

I assume "high discharge" does NOT mean that it will "discharge" fast in the vehicle. I think it means it can be discharged at a higher rate on a charger.

That's what I've always thought too. Do you ever see batteries with low "C" rating also say "High Discharge"?

Please don't fully discharge your lipo's. They can catch fire. Don't store them fully charged or fully discharged. When you are done racing, store them at around 3.85V per cell. Most Lipo chargers have a storage mode for doing just that.

guilo is right here. High C rating or discharge rate means for a given voltage, the battery can provide more peak amperage. Of course it doesn't matter how it's being discharged... whether in the car or on a charger, the battery will be able to dump more quickly (not that I've seen any charger that can discharge at an amperage near what your car's electronics pull).
