Default ammo box... (and a discharge/storage charge question)

so after spending the summer braving it... just stacking all my lipos on a shelf and leaving them, i picked up an ammo box yesterday.
figured it'd be best to have them stored in there over the winter.

do you guys line the bottom and/or sides of the box with anything? or just toss them in there?

also as far as storage charges go, all of my batteries are fully charged.
not sure if its bad to store them this way for the next 3-5 months.
how is best to discharge them to half?
most of my batteries are 2cell 4k and 5k mah and 4cell 4k and 5k mah
and i have a couple flight lipos. both 1cell

my charger is a thunder ac6

thanks

I put mine in a LiPo sack then in the ammo box with the lid NOT sealed to prevent build up of explosive pressure. If your batteries are fully charged, put them on a discharge cycle and set it for around 3.7V/cell cutoff then store.

discharge them to about 3.8-3.7 per cell..

about 80% charged that way they wont puff one you.. but i am sure 1 or 2 will.

and check them every few weeks to see if cells are droping voltage.

your charger should have a "storage" mode...


usually you store them at 3.8v/cell


edit: curse you uber fast typers...

i dont have a lipo sack big enough to fit all of them...
4x4cell
6x2cell
2x1cell
and misc airplane lipos

does a closed box really create too much pressure? or can i just drill a small hole on the side of the box. leaving it open just seems to make my OCD tingle

do i use a balance board while discharging?

ok. so my charger discharges to 12v for 4cell.
so i just use the balance board and watch the cells and stop it manually at 3.7-3.8 ?

I had a couple of questions about this myself. I have an Onyx 230 and I don't even know if/or how it discharges. I have always just charged and never discharged. I had some Turnigy packs go tit up on me after I left them outside
after using them so I guess the cold dropped them below the volts required to maintain and they won't work no more. If I can't discharge should I fully charge, run them for like 2-3 minutes, balance again, then store?

Would that happen? They pack them with ammo without worry of explosive pressure. I use ammo cans, sealed. Just curious if that is actually the case.

I've had an ammo box for a couple years now to store my lipo's in (all yr around) I actually kind of lined mine.. my never used lipo charging sack is folded over getting the duties

LOL

PS as the others noted.. 75-80% charge for store. I check my voltage monthly and do a short cycle on them after 3 months (charge, then discharge to store (via my hyperion charger).

You guys are crazy. Thousands of LiPo's across the country sitting on shelves and hanging on pegboards in local hobby shops. I haven't heard of any going up in smoke.

Put them to storage capacity and throw them on a shelf.

Those are brand new lipos... I have a wife, two kids and two dogs. I would never be able to live with myself if anything happened to them knowing it could have been prevented with a simple ammo can. For me it's more of a piece of mind.

Thunder AC6 can only discharge 5watts - thats all its going to be able to do, higher the voltage, lower the amp discharge rate.

You can put them in one of your RCs and run it down that way, will be way faster.
