Cart fitment & installation
Physical fitment guidance supplied by Qomolander. Installation requirements vary by cart and conversion.
| Cart / application | Fitment requirements |
|---|---|
| Plastic bucket-style battery compartments | Examples include Club Car Precedent (2009+), Tempo, Onward, and compatible Bintelli and PilotCar configurations. Confirm the actual compartment style and dimensions. |
| Club Car DS and Precedent (2004–2008.5) | Not compatible according to the supplied fitment guide. |
| Mounting bracket | Supplier specifies a CC3 bracket cut in half; obtain the mounting instructions for the intended cart. |
Electrical system: 48V class. This is physical battery-compartment guidance. Match the battery voltage to the cart's electrical system, controller and charger. Confirm tray dimensions, terminal clearance, mounting hardware and current requirements before purchase. Some conversions require minor modifications. A higher-voltage conversion needs compatible electrical components; physical fit alone does not establish electrical compatibility.
Bracket availability: Confirm the correct bracket and whether it is included with your order before purchase.
Ask Winnie's for fitment help with your cart year, make, model, voltage and a photo of the battery compartment.
