CRT.5 - My first conversion

[BrianG]

One thing to think aqbout is weight. A single 5Ah 2s or 3s pack will probably weigh less than paralleling cells and you get a solid 100A. And the 5Ah cells fit perfectly standing on their side on the CRT.5. With tall gearing and hard running, I was getting ~25-30 minutes of runtime.

As far as the BL system is concerned, anything on the smaller side should work well. A larger motor will weight more, but you'll have more torque for higher speeds.
