In my search for a "cash box" to charge in, I did find at the local Meijer on clearance, a metal lunch box for 8 dollars... I purchased a Marilyn Monroe lunch box... So do not rule out the a metal lunch box. I will be using this for storage at home also....

Be sure that it is made of steel or stainless steel and not aluminum. Aluminum has a melting point of 1200F, and what I have heard, a burning Lipo temp can reach 1000F. In a confined space, it could be higher.

For storage purposes, if it is made of aluminum, multiple bursting Lipos will surely melt it. For charging it may survive a single Lipo fire.

For storage I use several ammo boxes and spread out the Lipo inventory. This way, if a Lipo ruptures, it does not destroy your whole collection of Lipos.

I just looked up the melting point... I guess I just wasted 8.00, rather this then the other option... Man I was so looking forward showing up to the track with my Marilyn Monroe lunch box....

Question - How often are you balance charging?

Your Marilyn Monroe is probably big enough to also fit a lipo sack inside of it. You can double up a safety factor by doing that with style.

You should balance charge every time.

I agree and can. Just wanted to be safe at higher charging rates... I'm now looking for a stainless steal box. Even good cells can go bad... so no need for say 20 or 30 cost is a very small cost compared to the damage that could be caused by a bad cell showing up, with any battery...

Yes.
A 6-10 amp charge will not improve the IR as a 20+ amp charge would do.
The lipo batteries respond to the higher charge rate better....

Cycling your lipos to lower the IR may work at lowering IR somewhat but doesn't lower the IR as a higher 20+ rate.
The 45 minute low charge rate must cool the pack down to much???

The 20 or higher amp charge decrease IR dramatically just on the first charge.

I did notice having a older lipo pack in store charge for a month discharge at a lower IR after being charged and run at a higher charge rate once.
So the cells seams to be getting better.

Don't know why, but it works...

Alot of guys will use a small Ammo can.
You can buy one cheap at a Army surplus store.

Ammo boxes at home are ideal, but a steel Marilyn Monroe box looks better at the track!

Maybe skin makers can make wraps for ammo boxes so they could look nicer at a track.

ammo boxes are the best choice.
