berlingo electrique motor controller

[clumphillian]

New boy here....
Settled in to kalkhoff pedelec bike but that's no good for taking grandkids out.
Anyway, found an E500 Citroen with knackered controller so I need something suitable. Sagem was originally in. It's a Sep ex motor (whatever that means).
I'd consider complete vehicle with knackered batteries.
Come on! I've got 48 hours to decide....
