The got my A123 4s pack and rebuild it to 2x2 vs 4x1. I put it my Newbee and went from 330 watts to 520 watts. I was using 3s TP2100. I love the A123 pack. I hope I cam fix 2 4c A123 packs in aPulse XT. The packs is 52mm x52m x 140mm. I may have to go with 3s packs. I am still look for a Pulse XT so I check if they will fit before I order one.

I just won a ebay bid on a Dewalt 36v packs plus a used 4 cell pack on the way so I am fixed for A123 if I can make them fit. I will check a friend glwo version to see if the A123 will fit before I buy the arf.
