Big Cat 48V 13Ah- Lithium Ion Battery Pack (Silverfish) (Black Casing) Samsung

Powerful battery! Got me up the hill near my house no problem, and I am a 250 pound dude. Work is 6 miles away, and I only went down one bar in power by the time I got here.

The replacement battery pack is slightly wider than the original battery pack and would not fit through the bike tubular frame battery housing. This was also due to the fact that the bike tubular frame was not fabricated completely straight in that area. The frame had to be modified slightly in order to widen the area so the battery would slide into position. Once installed, the battery functioned very well.

GOOD TO GO/THANKS
