EZGO RXV Lithium Battery Mounting Bracket (BB51105-RXV1)

EZGO RXV Lithium Battery Mounting Bracket | For Epoch Big Box (BB51105)
Secure your Epoch Big Box lithium battery in an EZGO RXV with a clean, RXV-specific mounting solution.
When you remove hundreds of pounds of lead-acid batteries from an EZGO RXV, the battery tub suddenly has a lot of empty space. The EZGO RXV lithium battery mounting bracket is designed to help secure the compact Epoch Big Box battery in that tray, giving your lithium conversion a cleaner, safer, more professional finish than loose straps, wood blocks, or improvised brackets.
Built for cleaner lithium conversions
Drill-Free, Factory-Clean Installation
A better way to secure an Epoch Big Box battery in the EZGO RXV tray.
This Epoch Big Box mounting bracket bridges the gap between the EZGO RXV factory battery compartment and the compact footprint of a single lithium battery. Instead of leaving a high-value lithium battery loose in a tray originally designed for multiple heavy lead-acid batteries, this bracket gives installers a cleaner hold-down point and a more professional under-seat finish.
It is built for the exact-fit battery mounting problem that appears during an EZGO RXV lithium conversion: how to keep the new, lighter Big Box battery from shifting while preserving a factory-style installation.
Drop-In Fit for the EZGO RXV
This EZGO RXV battery bracket is made for RXV lithium conversions using the Epoch Big Box battery. It is not a flimsy universal battery tray that needs to be bent, cut, or forced into position.
No Drilling or Fabrication Required
The bracket is intended as a no-fabrication mounting solution for compatible EZGO RXV trays, helping installers avoid cutting the plastic battery tub, welding custom mounts, or improvising with loose straps where the intended fitment matches.
Ultimate Protection for Your Lithium Investment
Keep the battery secure when the cart moves, turns, and hits bumps.
A lithium golf cart battery is lighter and more compact than a full lead-acid pack, which is great for performance but creates a new mounting challenge. If a battery shifts inside the tray, it can stress the case, damage wiring, pull on gauge harnesses, or create unsafe cable movement.
This RXV-specific bracket helps hold the Epoch Big Box battery in place so your install looks cleaner and your wiring stays better protected.
Eliminates Battery Shifting and Bouncing
A secure golf cart battery mount helps prevent unwanted movement over bumps, hills, rough paths, and lifted-cart use. That means less stress on the battery case, terminals, communication wiring, and charger leads.
Heavy-Duty Black Bracket Design
Product images show a black, formed bracket with slotted mounting openings and a reinforced support shape. Epoch’s public listing does not publish the exact metal grade or coating specification, so verify material details if required for your installation standards.
Compatibility note
This bracket is for EZGO RXV applications using the compatible Epoch Big Box / BB51105-style battery. Do not order this for EZGO TXT, Express, Valor, Club Car, Yamaha, or GC2-style modular LiMAX kits unless Epoch confirms fitment.

Installation best practice
Test-fit before final tightening.
Before tightening hardware, place the bracket, battery, cables, charger leads, gauge wiring, and converter leads in position to confirm there is no interference. Verify cable bend radius, terminal clearance, charger airflow, and service access before completing the conversion.
