Right on. sounds like a hell of a good deal you've got from that setup.

The Turnigys have lasted twice as long as the original 24V LiFePO4 10A 3C pack (BMS failure?/overloaded cells?) :lol:.
The cells have done well for being protected buy some 100mm heatshrink tube. ridden through/left in rain etc no problems.
While these cells still meet me needs I will buy a new pack for my high power project.

If the controller is pragrammable then you might be able to re-configure it for 'soft start' so the throttle response isn't so twitchy at the start.

Do you think the motor might run better at 36V instead of 48V?

Sorry about he delay in reply. I've been busy replacing my kitchen.
I haven't had a chance to see if the controller is programmable or not. The bike gets used daily so I haven't wanted to mess with it .

I have got better at throttle control but to crawl along is a bit difficult on 57V you need to put it in a low gear ( 44T on front and 30t on the back results just under 30kph top speed. You can't pedal in this gear combination though at speed though and pedalling at low speed in this gear makes for entertaining one wheel action as on motor alone the front end gets light :lol:.
It might be better at a lower voltage like 36V due to the reduced rev range but its really a controller/throttle issue. I will put one of my high power controllers on it once it get the software done so haven't fully explored the options with the 6 fet ecrazyman.
I think part of it is that the throttle control on the ecrazyman is not that great but on that bike i was use to the original internal controllers stepped start which was horrible.
