Thanks - no doubt about the expected long life, but it's a consumable part, so it's just something that needs to get asked ....
Kin wrote:bah, this is such a curious development. Making me second guess my long term project [maybe not too long term, but cad-form for now] involving an Etek (clone- "mantra") motor. Is this the only thread to wait for conversation about how to manage slightly higher above-rating power usage? Just still polling for more information.
My controller supplier is already working on a 150A150V programmable controller solution for me, but he was whining about a regen cutoff at 147V last time we talked.

Arlo1 and I might have a solution that is 150V 150A capable with just 6 FETs. It's a work in progress but the FETs seem like they are up to the task and no it's not data sheet koolaid

Arlo1 and I might have a solution that is 150V 150A capable (continuous rating if we can get the heat sinking worked out) with just 6 FETs. The max voltage of them is 200V and 230A for a short burst (package limits them to 160A continuous up to 125C case temp ). It's a work in progress but the FETs seem like they are up to the task and no it's not data sheet koolaid. TO-220 FETs just aren't that good for high power, TO-247's and TO-264's seem to be where the fun is at.
*edit* sorry John, just realized this is your for sale thread, didn't mean to go off topic.

thedarlington wrote:nice man! any timeframe for when these will be good to go? i get the feeling ur hubs gonna become quite popular around the forum very soon, id personally be interested in 48v, any idea of what speeds you aim to reach for or are these more for torque since i read about a light version
