Lithium batteries are best stored at 50% charge if they are to last long.
No, I don't do it that way either - way to difficult. But still the best way of storing it - if it's the battery you worry about.

I fitted a lithium battery to my 7, (Yamaha R1 ), only a few months ago. It normally kept on lithium specific smart charger, but recently left it off for a couple of days. Seems I have a parasitic discharge going on, that flattened the battery in that time.
I think I've found the culprit ( self canceling indicator unit ), but the battery now won't hold a charge!
As once as they go flat they're knackered.
Most of these batteries have a protection circuit built in. I have a relay as master switch which discharges the battery as well. I have more than once forgotten to cut power and it still works.

Drain at rest *varies enormously between different Sevens. How was that unit wired?
* As we know due to revilla's research.
Is this generally true for the types of lithium batteries we're all considering for Sevens?
no you can recover them, I posted how to in a previous thread............. which I cant bl00dyfind now.....
Lithium batteries are everywhere in our daily lives, most have protection to prevent damaging discharge level, like phone and laptop batteries, but the lightest of them all the lithium polymer or lipo used in radio controlled models has no discharge protection. They puff up and become very dangerous to charge if abused with discharge beyond the safe limit. I have see a few lipo fires and the aftermath of a lipo fire in a house, all not good. Just look on YouTube for lipo fires to see the type of damage a small battery can do. As for putting on in my car, well I would, providing it lion based and has protection circuits to prevent over or under charge, after all these batteries are the basis of EV cars at the moment.

Any more experiences of lithium batteries in Sevens, please?
