Running a 36V 3.5HP motor @ 48V


 

Hi All-?

Currently working on a Citicar that has a 36V motor but a 48V charger. Were these models actually driven with 48V to the 36V motor? And I suppose that means I should be following the "48V model" diagrams from this service manual??

The car didn't come with batteries so I cannot tell from that unfortunately.

See below for photos of the charger & motor plates:



Thank you!?

James

Early ones were 36 volt and were changed by factory to 48 volt because of being too slow run as 48 volt

How many batteries are installed?


 

@Barton there were no batteries in the car when I bought it.?

Ok so what I’m hearing then is that it is OK to use 48V batteries even though it is a 36V motor, and it actually even came from the factory that way. Thanks all.?

I think it would be ok - motor may get HOT - There should be a fan to cool motor and a light on the dash
Send a picture of the battery compartment maybe there is enough room for 48v.


 

8 6 volt batteries

In my conversations with Bob back then, he commented more than once that the only change that was made with the conversion from 36 V to 48 V, was to add two extra batteries.

It all comes down to how they were fit in under the seat.?
