Hello all,
I have not posted here in a while, so I figured it was about time!
My first question is this: If I use a Kelly KDHB controller for regen with a series-wound motor, do I need a 2nd controller for propulsion?
More specifics:
I am working on a hybrid boat project. The boat will give river tours. 3 hours down-stream on electric only, 1 hour back up-stream via a 165 hp Honda motor. The battery pack needs to regen during that 1-hour trip.
I have determined that the battery pack charges at 56 V and 108 A max. I have heard that Kelly controllers are inadequately heat sinked, so I want to double those numbers for the Kelly controller rating or come as close to it as possible. I don't want to replace a controller, EVER!
Motor: Transwarp9.
Pack voltage: 48V (running higher voltage on the water requires extra protection).
Pack Construction: cylindrical 18650 cells.
Max pack discharge: 180 A.
Max pack charge: 288 A
