I am running 6 - 12v 6a smart chargers on my bike through three four pole single throw switches and off to each battery. That way I could isolate each charger from the battery when not charging (did not want to take a chance with the charger left in the circuit when riding the bike. I bought the chargers from Electricross, four packs very inexpensive, small, light, well built and seem to charge my pack well. I have a wopping 360 miles on my bike. Just added a Paktrakr and mounted the ammeter. Very curious to see how each battery performs. One neat thing on the paktrakr is the temp sensor built in. Way cool. I am evaluating the Paktrakr for the company I work for, so it hasn't cost me a dime. The ammeter I got on ebay from China with a matching shunt. 0-500 amps.
If you like the Frechia, my Honda VF is nearly as finished looking (okay the saddle bag battery boxes will be dressed up but I have managed to keep the weight within 30 lbs of stock. Just under 4kw battery pack of AGM, PMG, Alltrax. Need some new photos, trans is out, idler/jackshaft is in, geared for 60+. Glad to see so much action with other's bikes and other newbies joining the fray. Hope you all can commute on your bikes when you finish, my commute 8 miles round-trip. Working on the ducted motor-fan to cool the motor, maybe a timer or thermostat controlled, don't want to get too complicated ;-) Yeah, right!
