Lipo Charge

[Wassy]

Hello,

Should I be leaving my Lipo fully charged and balanced after every meeting?

How should I store them

Thanks
Mark

Certainly not fully charged. This can cause damage in long term storage.

If your charger has a "store mode" - most decent recent ones should - use that. Or just leave the packs alone after your last run (assuming you are not using up nearly all the capacity in your races).

ok, so just leave them with some charge in them?

Part charge, yes - full charge, no.

All manufacturers seem to differ slightly - but definately NOT fully charged, most that I've seen recommend something between 3.0v and 3.7v per cell (or about 50-60%) charged.

3.0V is WAY too low. That's basically flat. 3.5V is pretty low in my opinion also. My charger stores to around 3.85V per cell.

You did notice I put "50-60% charged" - right?

As I also said, it depends on the manufacturers recommendation.

Right ok, both my packets are sitting in my box fully charged!! Tell ya some people I have listened
too!!

I am not racing until the 14th what would you suggest, stick them on discharge for a bit

Yes 3.0V per cell is basically flat for a lipo at resting voltage.

3.85V per cell is approximatly 50-60% charged which should give you the least amount of cell degredation.

There are lots of things you can do with a lipo that will drastically increase the number of cycles you can get from them. If you want to find out some good info about lipo's then go here http://endless-sphere.com/forums/
