HI all,
So I have worked out that a MAC 8T is needed for my goals of a commuter 40km/hr cruising most of the time, and 50km/hr + for short bursts so I can merge with 50km/hr traffic when needed (a couple of 500meter bursts at most). I will be using 26” wheels a 1.5” slick tyres. The commute is only 9km to work and 9km back, I have the option of charging at work and at home if needed. For this reason, I'm looking at using a small lipo pack (with high discharge rate) and I'm aware of the possible risks using lipo.
It seems a 12S pack might not quite get me upto 50km/hr and I need a higher voltage? Comments on this are welcome!
A 59.2V nominal 16S (4 x 4S 5000mah packs) is appealing as I can easily parallel up 2 x 8S packs for charging using a RC charger. Has anyone used the Mac 8T on such a voltage or higher? I would love to hear some comments regarding:
- Speed?
-Controller used? I'm looking at EM3ev 9fet high voltage controller, or should I be looking at the 12fet version and reducing the current in software.....eg 25 or 30amp limit as not to stress battery and/or motor
-Throttle response – Does it get twitchy at high voltages?
-Any other problems ?
Thanks Steve
