I'm slowly replacing my MA packs: two 2s2p 8Ah packs and two 2s 5Ah packs. Both have never puffed or anything, but I combined the 5Ah packs into one 4s 5Ah pack to use in my Slash (figured the higher voltage/lower current will be easier on them).

The 4s 5Ah pack works well in the Slash with a 2200 kv motor, geared conservatively.

But the 8Ah packs left me very disappointed. I attempted to take them apart to reconfigure into single 4s1p 4Ah packs (for the Slash). I say "attempted" because the tabs were already showing signs of tearing they are so thin. Might as well call the tabs "foil". And there was no solder connecting the 2p cells; I was able to seperate them by hand with no soldering or anything. I decided they weren't worth the effort and will just toss them. I plan to show my son first-hand the possible dangers of abusing lipos by taking the raw cells outside and puncturing them. Might overcharge a couple too. Sometimes kids need to see these things in person before they respect what can happen if things aren't treated right. But, when I took one cell outside and puctured it, it just got somewhat lukewarm, so there goes that lesson. lol, the packs aren't even good enough for an object lesson!
