Or you could just buy 4s packs? These are commonly available, cells are identical, however the connectors are plug and play with the BMS (one of the best features of the controller IMO). Your experiences with your motor running better on a particular voltage are due to limitations of the controllers you have used in the past, nothing to with the battery voltage. Your motor doesn't even see pack voltage.Microbatman wrote:Any plans to make a controller that will support 100+ volts?
The reason for asking is all about battery choices.
Your current controllers are not compatible with running Four 6cell packs in series. That = more than 100 volts.
A typical setup using your current controller would be Four 5cell packs in series so you would be less than 100Volts
For example. I have a crystalyte X5304.
My X5304 does much better at higher volts. >80
It does not like running a 20cell lipo setup as much as a 24 cell lipo setup.
So if I buy your controller I am forced to shop around for lipos in 5 cell configurations.
There are NOT a lot of choices in lipo land of 5cell packs.
There are many 6cell choices in lipo land.
So buying the controller as you have it now = limiting my battery shopping choices to 5s configurations as 6s will be over your limits.
I want to buy a 10,000mah6s or larger and run 4 of them in series=100 volts..
There is no point in going to a higher voltage FET. The power potential at lower voltage (~90v) is simply higher with current FETs. Not to mention less risk (>90v is becoming hazardous, 130v+ can be deadly)
Many of the reasons for higher voltage do not apply with these controllers. Motor RPM is not limited to pack voltage with OVS. Performance can be controlled precisely, you do not have to increase voltage to increase power. The only possibly valid scenario is when you're limited to a specific motor KV, however this scenario is becoming quite rare as availability of different windings for high performance motors is much better.
