EZGO F398 Battery Questions...

[Off-Grid Organics]

Just purchased yesterday and know very little after a few hours of study. From what I have garnered, it appears I have a 1998 w/36v system. That said, why do I have 6, 8v. batteries??? All the batteries are shot, but the cart is in really nice shape, appearance wise. Just curious if this rig has been monkeyed with?

Sounds like it has been upgraded to 48V for more speed and torque.
That means the controller has been replaced also.

Is the label on the controller visible? If so, what is it?

Arrrrgg! Thanks for the reply! I assume the controller is the box beneath the solenoid? If so, the sticker is not readable...it has a 1-2-3 on the spade terminals, and an A2 off to the side. While looking further, the motor is an Advance DC motor, W80097...and it says 36/48v

Yep, controller is the box under the solenoid.

Is the case black or is it blue and white?

Also, only three spade terminals on top. With or without wires attached.

No color...aluminum. All 3 spades have wires attached. Is my 36/48 motor an upgrade?

Not sure what the controller is. Attach a picture of it and somebody ought to be able to identify it.

Probably a stock series drive motor. Motors are not very voltage specific and motors rated at 36V typically run better at 48V. In fact, upping the battery pack voltage is the only way to increase both speed and torque without changing the motor.

Hopefully a 48V charger came with cart.

I'll get a pic manana...yes, the charger is a 48v. Yesterday I plugged it in to see if anything would happen (batteries toast)...looking for any amp needle bump...nothin'...but that doesn't necessarily mean the charger is bad, right? Again, thanks for your help!

You’re in the best hands with johnnieb, but no, because the charger won’t come on doesn’t mean it’s toast. I’m not positive about all of them, but most need to sense a minimum voltage. You can bring them up separately with a regular battery charger. What’s the total pack voltage right now and voltage of each individual battery?

I got that impression! Thanks! Glad to have found this forum...been scratching my head! These batteries are toast...a couple still wet, the rest bone dry. Poor thing has been sitting for years in a garage...pretty clean rig...pics in the am.
