How long is safe to leave lipos charged for????

[HELIMAD]

Hey guys, a quick question. How long is it safe to leave lipos fully charged for, i herd that if left for to long it can affect battery life. Cheers

I dont know about fully charged but if they are being left long term they are ment to be charged to 50% I think!

In theory they are best left on the shelf a 50-60%.
If they are fully charged keep them warmish, over 10C. Fully charged and cold is bad for them . wen they are cold their capacity shrinks and they become overcharged.

I have several revolectrix 2100 3S packs for my 450 one of which is a year older than the others. They have always been kept fully charged and I can't tell the difference between the packs flying my 450. So the negative effects of leaving them fully charged must be small!

I only worry about charging to store level with my more expensive trex500 5S4200 packs.

LiPo Storage charge level should be 3.85v per cell so a 2S = 7.70v, a 3S = 11.55v, a 4S 15.40v, a 6S = 23.10v.

Storing fully charged for a couple of weeks should not cause harm, but for long term storage, discharge them to Storage charge levels.

I should hope not!

Mine have been charged for weeks and not used due to the great summer weather

as Gordon said its the cold rather than the fact their fully charged that does the harm.

This time of year even with the naff weather I think you would be extremely unlucky for the temp to drop below 10deg but watch it in the winter.

I don't disagree..... sometimes mine are left fully charged for quite a long time lasting several weeks - and kept indoors - so lower temps should not be a problem....

But to be absolutly safe, the manfacturers recommend long term storage at Storage charge (as they are shipped)... so wheras in practice I personally chose to take the risk, I personally would not actively recommend others to do so - just in case.
