They are more like 10C in reality
IR ( according to the iCharger ) is double versus the 20C Turnigy packs.
Their strength is that they are smaller and lighter. You're best off running a higher amount of amp hours and lower C, like 5C or less continuous/peak.

Brand new to the forum and new to doing mods
I have an EVG too with working Heinzman geared 500W brushed motor - everything is stock except a LiMnCO2 10ah 36V bottle battery instead of the awful lead acid.
I live in Colorado - would like extra power and a little more speed (maybe 25-30 mph max).
Use the bike for errands, 10 mi ride to the lake for a run, occasional dirt road/trail action, lots of hills.
Any thoughts about what I might put in the way of a setup for a front motor?
I love the versatility and simplicity of the Pie but is that just way too much motor and weght?
Thx in advance.

The phase amps is just for startup, creeping and acceleration, which at one point crosses over to the battery amp settings when the throttle increases. The 40/60A settings worked, but the timing between going from phase to battery Amp settings was too off. At 45/66, it is near perfect. I'm going by the 1.5 multiplier over the 2.5, since the bike is running on 24s and the Magic pie being a torque motor already. I don't think I would be able to get away with the 1.5 multiplier with my old 500w Ebay motor.
Increasing the phase amps(2.3-2.5 multiplier) will increase my torque during acceleration, making for a nice zippy ride. But that is dangerous when you have 500-600 other bikers around you. Hence my new toned down settings and see how the bike reacts. So with my morning commute, the bike had good acceleration. No wheelie popping startup torque, but a nice linear power band. Climbing power on the inclines in the parking garage was good too. I'm going to a 1.6 multiplier soon and see if that buzz(timing issue?) is reproducible or not.
