| Controller | Alltrax AXE 7234 Be careful with lithiums - the current limit on the AXE is averaged - with low esr batteries, your current can spike to 200% of the current limit for short periods. Recommend limiting top speed to 80-90%. | ||||||
| Batteries | 12 Dewalt DC9360, 36.00 Volt, Lithium-Ion Nanophosphate Lithium. These batteries are unmodified DeWalt 36 volt battery packs. Mounted in hacked up flashlight bases. I run them 2S6P (72 volts, 13.8Ah) | ||||||

| Geared this way and with 150 amp current limit still has plenty of gusto. No problem zipping up 5% grade at 45mph. Thanks to all of you who have done conversions and showed them on evalbum.com. I visited this site often for ideas and inspiration! Hope my bike helps inspire others. Range is only 8.5 miles but only limited by $$$. My commute is 7.5 miles - a very pleasant and fun 7.5 miles on this 220 lb bike. My recommendation - just say NO to lead acid folks - you'll never regret it... | |||||||
