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.

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.
EZGO RXV Big Box Mounting Bracket FAQs
Common questions about fitment, battery compatibility, hardware, and secure lithium installation.
Will this mounting bracket fit my EZGO TXT or Express model?
No. This exact bracket is designed for the EZGO RXV battery compartment and is not a universal bracket for EZGO TXT, Express, Valor, Club Car, Yamaha, or other cart platforms. Those carts use different tray layouts and require different mounting solutions.
Is this bracket meant for the single Big Box or the multi-battery LiMAX kits?
This bracket is intended for securing an Epoch Big Box / BB51105-style lithium battery in a compatible EZGO RXV conversion. It is not intended for modular GC2-style multi-battery LiMAX setups unless Epoch specifically confirms compatibility.
Why do I need a mounting bracket for my lithium battery?
When the original lead-acid batteries are removed, the EZGO RXV battery tub has extra open space. A compact lithium battery can shift, bounce, or slide if it is not properly secured. A dedicated bracket helps keep the battery in position and helps protect the case, wiring, BMS leads, gauge harness, and power cables.
Do I need to drill holes into my golf cart to install this?
This bracket is designed as an RXV-specific drop-in mounting solution intended to avoid improvised drilling, cutting, welding, or fabrication where the cart and battery match the intended fitment. Always test-fit the bracket, confirm model-year compatibility, and follow Epoch installation guidance before final tightening.
Does this bracket come with installation hardware?
Epoch’s current public listing does not publish a detailed hardware-included list. Before starting the job, confirm whether mounting bolts, washers, hold-down hardware, or straps are included with your order, and use hardware appropriate for your RXV battery tray and battery installation.
Can I just use ratchet straps or bungee cords instead?
Using bungee cords, ratchet straps, wood blocks, or zip ties is not recommended as a permanent lithium battery hold-down. Straps can loosen, stretch, fray, or shift over time. A rigid mounting bracket gives the battery a cleaner, more secure, and more professional installation.
Will this prevent battery movement on rough terrain?
A properly installed bracket helps reduce battery shifting and bouncing in normal golf cart use. If your cart is lifted, used off-road, or carries heavy passengers or cargo, inspect the bracket and fasteners regularly and verify the battery remains secure after the first few rides.
What should I check before ordering?
Confirm that your cart is an EZGO RXV, that your battery is the compatible Epoch Big Box / BB51105-style battery, and that your tray area, cable routing, battery terminals, charger wiring, and gauge harness all have the clearance needed for a clean installation.
