Do you know these guys? Lots of interesting stuff (cells, BMS, chargers, etc) there, and not that expensive too. Just don't know anyone who dealt with them.
I was talking LiFePO4 not LiPO btw.

3: for the same (or lower) price, you can get the good cells out of "dead" laptop packs, they'll be high-quality cells, even if they're a little worn, and you have to sort the dead ones out from the good.
4: I should talk to the local recycling company to see if they can provide me with free laptop batteries. (They probably won't, but who knows.) Buying them overseas from ebay seems like a silly thing to do, even if they're cheap enough to be worth the effort.

I thought so, miniinthebox is dodgy in the reliability of data, if not the stuff itself. But I got some good cheap LED grids off them.
