TSDZ2 With 15S (55V Nominal/63V Max)

[Parad1gm]

Anyone try this? Does the OSF support changing the top end voltage? The capacitors and mosfets I believe are good up to 80V stock

You really should read the mega threads on the TSDZ2 here, i know they are long but there is a wealth of good info in them about all sorts of topics - as far as I recall 60V is the max anyone has really pushed through this controller. I've used a 1500W DC-DC booster to hold battery voltage at 60V and it works fine, I've not tried any higher as I believe the caps are 63v max.

These are some of the key threads on the TSDZ2 here - some are verrrry long!

New "TSDZ2 Torque Sensor Central Motor"
TSDZ2 OSF for all displays, VLCD5-VLCD6-XH18, LCD3, 860C-850C-SW102.
Hardware temperature control tsdz2

There is also a lot of info and code in github relating to the TSDZ2

Having said I've never heard of someone upping the voltage - i just read this recent post...

I have flashed it on my bike now but I have diy 16S battery and i upgraded the Caps to 100V on the controller.

1500W regulator? Thats a great idea. How do you gauge the remaining capacity? I think the cells I'm using pretty much stay near the top end performance wise until they need charging, but good idea. Haven't thought about that. Does it screw with the current though, reducing performance ?

For lead acid batteries I could see many situations this would be useful as well.

Basically, all I'd need to figure out is how I can get max speed/performance just from the pedals..because come to think of it when the throttle was connected the speed with open throttle using a 52v pack was good enough..but haven't figured out how to get that using the OSF and the pedals alone..

So I made the custom 16S 57,6V battery which would be 67,2V fully charged but I burned 2 controllers to find out that something inside the controller does not like more than let's say ~ 65-67V so I charge it up only to 64,8 and it works. Peak was 1100W i've seen so far. But it also happens on lower rpm so I have a lot more Nm Torque. I wish the OSF would have phase current setting instead the battery current one. Since I wish I could ride with the nylon gear which only brakes because of to much phase current.

60kmh is possible but you also have to be fit to pedal a bit

EDIT: I have the ebikestuff cooling kit installed and I monitor the temperature.
