Exact-fit lithium battery mounting
Secure your high-capacity Epoch lithium battery with a purpose-built mounting tray for RVs, camper vans, boats, and off-grid battery compartments.
The Epoch 12V 300Ah battery tray and 314Ah lithium battery mount is designed for the Epoch 12300A-H battery tray application and 12314-ECO tie-down bracket fitment. It gives DIY builders, RV owners, van converters, and boaters a cleaner way to secure a large lithium battery without building a custom plywood box, welding a frame, or relying on loose straps that can shift during travel.
High-capacity lithium batteries need a secure mounting solution.
A 300Ah or 314Ah lithium battery is lighter than a comparable lead-acid bank, but it is still a large, high-value component that should never be left loose in a battery compartment. Sudden braking, washboard roads, rough water, or off-grid trail vibration can cause an unsecured battery to slide, bounce, pull on cables, or strain terminal connections.
This exact-fit lithium battery tray helps keep your compatible Epoch battery planted in place, protecting the case, inverter cables, busbar wiring, and terminal connections during travel.
Designed for Epoch 12300A-H and 12314-ECO battery footprints.
This tray is built for the Epoch Essentials 12V 300Ah battery and the Epoch 12V 314Ah Eco Series battery. It is not a sloppy universal tray that leaves excess room around the battery or depends on improvised blocks to close the gap.
Prevent movement before it becomes electrical damage.
When a battery shifts, heavy inverter cables can pull against ring terminals, busbars, and battery posts. A secure tray helps prevent vibration-related loosening, cable strain, terminal movement, and potential short-circuit hazards.
Tight turns, sudden braking, potholes, gravel roads, and boondocking trails can all shift a loose power bank. This RV battery mount helps keep your Epoch lithium battery secured in battery bays, under-bed compartments, dinette benches, and off-grid electrical cabinets.
Heavy wake, chop, trailer launching, and vibration can make an unsecured battery move inside a hull or compartment. This marine battery tray 300Ah solution helps keep the battery planted in protected compartments and reduces stress on terminals and cabling.
A rock-solid tie-down system without welding, cutting, or custom woodworking.
Mount the rigid tray to a solid floor, shelf, or compartment deck, place the compatible battery into the tray, and secure the retaining components so the battery stays in position. It gives DIY installers a cleaner solution than loose straps, wedges, or improvised plywood boxes.

Exact fitment, installation, battery security, and mounting guidance.
This exact-fit mounting tray is designed for two Epoch models: the Epoch Essentials 12V 300Ah battery, SKU 12300A-H, and the Epoch 12V 314Ah Eco Series battery, SKU 12314-ECO. If you have one of these two batteries, this tray is the intended Epoch mounting accessory for that footprint.
No. Battery case dimensions vary widely between manufacturers, even when the advertised amp-hour rating is similar. This tray is built around the Epoch 12300A-H and 12314-ECO case footprint, so using it with other brands may leave the battery loose, misaligned, or impossible to secure correctly.
A high-capacity lithium battery can still weigh around 57 to 58 lb. If it is left loose in an RV bay, camper van cabinet, or boat compartment, sudden braking, rough roads, or heavy wake can make it shift. A secure tray helps prevent casing damage, cable strain, loose terminal connections, and dangerous electrical shorts.
This tray is intended for standard upright, flat-floor or flat-deck mounting. It relies on the tray base and retaining hardware to secure the battery against a horizontal surface. Do not use it as a wall-hanging bracket unless Epoch provides written installation approval for that orientation.
A structural battery tray and tie-down system is consistent with professional RV and marine installation best practices, because batteries must be secured against movement. Specific ABYC, RVIA, or local requirements depend on the complete installation, vessel, vehicle, hardware, and mounting surface, so confirm applicable standards with a qualified installer.
You will need basic hand tools and the correct mounting fasteners for your surface, such as wood screws for a plywood RV floor or through-bolts with backing washers for a metal or fiberglass deck. Mount the tray to a solid surface, set the battery into the tray, and secure the retaining hardware according to Epoch guidance.
The product images show the tray assembly with small hardware and retaining components. Because the public product listing does not publish a formal parts list, verify the exact included hardware with Epoch or inspect the kit before installation. You may still need surface-specific screws, bolts, washers, or backing plates for your RV, van, or boat.
Yes, it is a good fit for protected marine battery compartments where the compatible Epoch battery needs to be secured against wake, vibration, and hull movement. Use corrosion-appropriate fasteners and mount it to a structurally sound deck or shelf, away from standing water where possible.
