Default 42v Western to 48v

Friend put 6 - 8v batts instead of 7 - 6v
In his Western 42 v cart.
Says it picked up some speed & ran it
for 18 holes.
95 , 97 ? model,
Think the older 42 westerns are 36V
motors & controllers .

Think he may burn up solenoid & controller
Or
Is it a cheap upgrade?
(+ only need to buy 6 batts)

how is he going to charge the 48 volt battery pack? I assume his charger is 42 volts as that is what he had before putting in the wrong batteries. I have two 42v western carts and they are currently faster than many 48 volt carts in my neighborhood.

Trouble is the surface charge. When charging the 48v pack it will get to 59+ volts in the finish phase. So if he hops in and hits the gas 30 minutes after a charge cycle completed then his cart that is set up for 42+v will see 59-ish volts. Or, he may have a controller and solenoid that are 48v compatible and be OK.

It'll either be fine or let all the magic smoke out of the controller/solenoid.

I know it's not answering your question, maybe someone else can chime in that knows this stuff.

You do want to be careful with the max RPM of the motor, I don't know how fast he was going on 48v. There are a few members who've exploded a motor by spinning it over 6k and it normally takes out the controller when the motor goes like that.

I think the older Western’s have 36 v
controller .
They made a 42 volt charger , Added a battery..
Wa-La.. a good 6 volt upgrade.
Some controllers are 36 to 48v
This one ,I think is a 36 v controller.
Looks like a 0-5k speed control?
(Not sure when EZ went ITS)
..
But his test (so far) shows that some of the older
carts had some skookum 36v controllers .

Uhh, not even close... Not even 30 seconds after the charger shuts off ..
Go measure a pack 30 minutes after the charger shuts off...
