Should be 3 shunts which means the controller is expecting a 1.33 mOhm shunt. Typically 3 shunts ends up around 1.2x mOhms. Try 1.25mOhms and then start calibrating from there based off of how many amp hours you drain from your fully charged pack vs how many you put back in. Then calculate the error percentage and multiply the shunt value times that. I.E. you pulled 10Ah from your pack and put back 9.5Ah. 10/9.5 = 1.05263% difference. If your shunt is 1.25mOhm multiply it by 1.00105263 and you find out your shunt value is now around 1.316mOhm. Do this 2-3 times and you should have a shunt value that is fairly accurate.
I've written how to do this process before if you search through my posts.

Many thanks. I've seen your post (saved on my computer) but was looking for the starting point.

great info

. My new build seems like its using more power on the screen than it is in reality.
i'll try 1.0m mohm

hi lyen
is this controller overkill for a 1000w conhismotor
i am running 48v a123 20ah 20c prismatic battery cells from osn with a 50amp bms
at the moment i am running your 12 x 4110 MOSFET Extreme Modder Controller LYEN Edition $129
but was looking for a bit more go

Why dont you try boosting the current on you controller you have now? This controller is really for if you want to do high voltage and gain more speed with the power with that. No gain to be had if you stay at 48v.

Do any owners of this model have experience with bumping the current up a bit (on an un-modded unit)? Just curious how hard I can push mine. It's running at the stock 45A now on 24s. 55 or 60 would be good. Thanks

agree with trevc above, just got mine will trial 60amps unmodded, hopefully doesnt fail.
More importantly the main feature I really would like to be able to programme is regen over 75v. Why is that the maximum on a controller listed at 84-132v?
thanks
p.s. I bought this off another member who bought it from Lyen, so I didn't have a chance to ask for customizations

If your trying yo program it, all the voltages are double in the menusfor the 4115 controllers. Well with the software iI use it is.

link to the software? thanks
Newb said something about xpd...
wish i had more time to finish my soldering of the plugs

70mph is some serious speed... do you have a build thread? Assuming you are running 120v+ on a MXUS3k 3T?
Any grease is better than no grease.
The best exercises are the ones you enjoy doing.
I strongly prefer vehicles without doors.

+1 I too want to see a build log!

Lift your back wheel off the ground and then WOT. You too can have 70+ MPH displayed for a quick photo
