Yeah, I’ve been AWOL, but working hard… Thanks to my AWESOME friend and SPONSOR, Mike Corbin (of Corbin Sparrow, Sparrow Motors and Corbin Seats fame, oh yeah, and general ELECTRIC MOTORCYCLE LEGEND) I have about 3kwh of CALB Lithium Iron Phosphate (LiFePO4) packs, ready to strap into the bike. Here they are, in their yummy deliciousness:
This will give me about 40ah (at 76V)… just about the same as the Brammo Enertia I rode to work that day, way back when, about 26 miles on Route 128 in rush hour. The total weight is around 50lbs.
They’ll mount on my rack system, but to do so I have to add a second module mount under the belly of the bike, right about where the expansion chambers were on the original. So that’s what I’ve been up to- making another rack, and getting it mounted to the bottom of the frame.
Here it is:
This is the module as it will sit in the frame.
Here’s the complete module, upside down, with the rack removed:
The complete module with rack installed:
The modules will be set up with 12 packs in each module. Wired in series, they’ll give me about 38V at 40ah. The two 38V modules will series together in the main harness to total 76V and 40ah.
The modules have a few other things in their future… at 38V I can use them for the scooter, the trail bike, the tractor and even the lawnmower. The Battery Module concept in action!
