I do run a 30AH battery at 52v though, I will warn you 15AH batteries with only get you 20 miles or so. I got a custom one built with a custom frame bag which barely fits, adds 5kg but the extra range and power is totally worth it.
Can climb 5000ft in eco 2/3 and do around 50 miles hard graft.
I can confirm I have been running the new exess controller for some time now @40Amps and it was absolutely the best thing I could have hoped for, i run mainly in turbo 1 and sometimes 2 as that is more than enough power. Even slow cadence is not much of a problem although after running off road...
Thanks for posting your settings, I have recently got my ultra up and running it turns out the stock settings on these units are absolute dog turd.
Tested your settings and they're better than I previously had but still need a lot of tweaking.
Does anyone know if you can use the pas sensor...
Would you mind posting some more pictures I really like your set and the titanium one to be fair, I'm currently debating whether to get the full sus or the Ti but with a thudbuster.
Impressive bikes fellas!
Hi,
Thanks for all of the great information you have really inspired me to begin to build my own ebike, I was wondering if you wouldn't mind shedding more light on your battery pack installation and how you manage the cell health?
