Cart fitment & installation
Physical fitment guidance supplied by Qomolander. Installation requirements vary by cart and conversion.
| Cart / application | Fitment requirements |
|---|---|
| General application | Broad physical fitment for many golf carts, subject to battery-tray clearance and mounting requirements. |
| Club Car DS | Fitment is not confirmed; contact us before ordering for this model. |
| Club Car Precedent (2004–2008.5) | Requires moving the center console. |
| Standard 2 × 3 TXT-style battery tray | Use the EFLOW-TXT-150/230 bracket. |
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.
