Wanted: 4QD PRO/120 or similar/better (Pair)

[Dom]

As per title. Anyone want to sell off a pair of these controllers for not too much dollar?

The world has moved on quite a bit from 4qd pro 120s. Why those in particular?

I'm showing my age now aren't I haha!

Only because I am familiar with them and also being old kit someone might have some gathering dust somewhere that they would be happy to get rid of cheap.

Aside from that, any speed controller of that voltage/current rating would work well. Looking for 24v-36v controller capable of driving two powerful wheelchair motors each for prolonged periods under a fair bit of load.

Or could go one controller per motor for added redundancy if they were cheap enough but gotta try and keep the cost down.

Dom, I'd go look at something like a ragebridge. Nice modern controllers, current limiting etc. I used a single rage to control two T64s on 6s at series 9 and they were brilliant. Can either order from ranglebox in the UK or direct from equal zero designs in the USA
