New 540C-7XL pics dissected,

[zeropointbug]

Yah, i bought mine way back in July when the first came out, i have been watching them since fall 2005... the kits i bought were $100 each, i bought two of course @ 6 cells a kit.

I made the pack into 2 cells together in parallel, then 5 of those in series. Now with this BL system i am attempting to direct solder the cells, which is not recommended. They say the only outcome is reduced cycle life because of the heat of the iron. But i have a good way of very quickly soldering and then rapidly cooling it down.

We will see.

You must have spent a lot of money on those developer kits... I got a Dewalt 36v battery on Ebay (10 M1 cells) for $101 shipped that will become 5s2p :027:.
