seems like you could do with the hard tail on the road and the full suspension on the trails!
I would like to compare your pie on 87 volts to my mac on 60 volts. It's a shame I can't off road with the mac. I hope to buy back my friend pat's pie for very little
and make another bike, in a year or 2. I would probably run the same voltage as you but I wouldn't have the issue with heat as you did with you're LiPo, by the way what LiPo were you using ? the zippy's get fairly warm if I run full throttle for 10 miles and climb steep hills, so maybe the Texas heat might take it's toll on them ?
I could use the battery I have now and swap it from the mac bike to the pie bike, but just remove or add the packs I want for the voltage I need, that's what I like about Lipo, and it kinda makes up for the lack of BMS.
All I'd have to do is add another 2 x4s or 6S packs for 74 volts or 81 volts nominal, though at 91 volts might be too high for the infineon, but I could get 33-35 on 16S LiPo with the infineon set to 120% speed, so close to 40mph on 20S LiPo would probably be more like it.
On the cycle analyst I see peaks of 75 amps, so that's about 4200 watts peak, through the mac! Don't tell cell-man!
Back to pedal only power.
