you have a pmI will soon be replacing my Zapi H3D 800a controller for new higher voltage unit, therefore the controller and a NG3 120v charger will be available for purchase.
I have used them in my VW golf conversion for the last year. I had both units serviced by Electrofit zapi this year.
The controller comes with a programming console. It also has Regenerative braking which you can adjust or switch off. I find the regen works fine with the 9" advanced Dc motor on a low setting. Manual and wiring diagrams included.
The Ng3 charger has been set up for 150ah trojan batteries. You can change the charge patterns.
I'm asking 1000 pounds GBP (1582USD) for the pair. 600=controller 400=charger
