    7s Zippy compact balance wires question

    I am building a new twin motor bike. I really wanted the extra cell as opposed to 6s, it should push the voltage closer to the e-bike kits limit. I really want to do some off-roading. So I ordered 10 7s 5000 mAh Zippy Compact packs. They don't show the balance wires in the pictures but I assumed...

    Turning down 9 amp Ping Charger?

    I am out on the road with the new Atlas (pics in the build thread). I had 25 Ah of battery but right before I left I sold 10 Ah to a friend that really needed it (disabled vet). I have a 9 amp Ping charger that I was using to quick charge the 25 Ah, I gave my Soneil 3.5 to my friend also. Side...

    Sun Atlas Cargo Build

    I've been working in a bike shop for the last few years building e-bikes. Built my first e-bike 2008 and never looked back. 50,000 miles or more later I still love it and have stayed committed. Just finished my second year in college seeking a E.E. degree which means I haven't learned a darn...

I have a customer who wants to install a hub motor on his recumbent with a 16" front wheel. We deal primarily with e-bike kits but they do not have a 16" wheel hub motor...

    Are Nano-Techs worth it?

    I am finally going Lipo. Not really in the pursuit of speed but range. I've been wanting to build a long range pack for quite a while now, say 75 to 90 Ah or more for my long distance road trips. I will have to get a bigger bike if I want to stay with LiFe. I am only going 12s, that way it will...

    9 amp charge too fast for 25 Ah of LiFePo4?

    I have a Ping 48v 15 Ah battery in paralell with a 48v 10 AH Headway battery. These batteries have always been charged and discharged together and always reach full charge at the same time. The Headway I don't run with the BMS but I do have sense wires so I can balance charge every 5 to 10...

    Questions about SLA and lithium together ?

    I recently lost my 48v 10 Ah battery in a near head on collision with a coal truck. Eventually I would like to build a new lithium pack for my bike. But today the guy in the local battery store offered me 4 barely used Yuasa 12v 22 Ah batteries for 20 dollars apiece. Seems like a good deal to...

    Raising charging rate on Soneil charger

    I am using a Soneil charger for my Ping batteries. It's rated at 3.5 amps. I already had to raise the voltage to 60.5 from 57.5 that it came from Electricrider that was LiFePo specific. This was achieved via a tunable pot inside the charger. Near this was another tunable pot that was epoxied...
