The initial current during take off for the Pie with the MC seems to be limited.
Like if I pull the throttle on hard I read the CA and Im lucky to pull 5 amps holding the bike at a stand still.
When testing the inductance of the Pie it came short of the HBS.
Side by side comparison MP to HBS is once the MP gets a little RPM happening the current shoots up very high into the good hill climbing ability category.
If you want the Pie to take off like a rocket, a small wheel diameter allows the RPM to go higher at the initial take offs.
Another fast solutions is to get 12 fet controller mod it to do 60 amps max and double the MAX amps by using two packs.
Some of those infineon controllers can easily do 40 amps at 72v 2880 watts, at 48v 60 amps is still 288o watts so this works well.
A big fat C rate pack and current into the 60 amp mark will certainly get the bike going off the mark.
The efficiency could possible be regained with a lower continuous setting.
At ES they are suggesting a 2.5 phase current to 1 pack current ratio is good. 60A max 24A cont.
The MC can do 50 amps max without a hitch if you open up the shunt path and good cooling.
A lot of heat can get up over the controller shunt and feed it to the fets, again, I think the meager 20 amp shunt is evil. The software is fine to manage the currents so to control more current into the controller.
Problem we are having is the GM controller is designed for the GM
BMS. When we add another shunt with a CA standalone even though its a 100 amp max shunt. it still adds ohms to a circuit.
Othe
BMS's may have a shunt in them too.
By the time the current gets to you motor its been through three resistors. Software management starts to lose its accuracy when all these shunts are already doing the AMP limitation.
Ha Im almost tempted to bridge my shunt full closed and just use the Ping
BMS shunt and use the software to control the whole thing.
The software does work if you give the controller something to work with.
That daid if you want a pocket rocket go for a P string of cells or better still a dual pack.
Choice Dual Pack vs Dual Pie. I would go for the second pack in a heart beat.
You can get the second Pie after you get the second pack up and running.
The dual Pie I see now why it is good. It will double the torque in this take off moment the MP is at its weakest. You don't need the second pack just a second Pie.
However the second pack gets you better range and better life span if you desire to Push your motor/s to the max.
