I have made a couple of battery packs for people. My costs are usually about half a new pack. You need to send me your original pack so I can reuse the BMS, and hook it all up. I use Tesla Model S cells. My buddy and I buy tesla packs and we take the modules apart and use the individual cells to make packs. We can also turn a tesla 6S74P into a 12S37P battery.

The Tesla cells are 18650's and are 3,100 mah.

I made a pack for an A2B a little while ago. Pics are below.

I use the batteries out of tesla's mostly. I don't like LiPo's, yes they are dirt cheap, but 1 fire will wipe out all the savings. Tesla batteries have more energy density than LiPo's and a TON more energy density than LiFeO4's.

If you want more info PM me.

The red cells were the original cells, the blue are the new cells.

On the The L3 52v 20.3Ah Panasonic triangle battery | electro bike world, I was a bit concerned when I saw all the current going thru 1 8mm wide strip of nickle. I hope they have a couple of layers. If not that pack is only good for about 20amps max. I looked to see if they gave a max amp draw, but I did not find it anywhere. But I would say that is not a high power pack. But is a good pack for 20 amps or less.
