The ECO-WORTHY EnergyRock 12V 314Ah LiFePO4 Lithium Battery is the higher-capacity successor to ECO-WORTHY's 280Ah metal-case battery. It stores about 4,019Wh (314Ah at 12.8V) in the same style of rugged metal enclosure, built for RV house banks, camper vans, boats and off-grid solar storage.
A smart 200A Battery Management System (BMS) protects the Grade A LiFePO4 cells against overcharging, over-discharging, over-current, short circuits and overheating, and automatically stops charging in low temperatures. Built-in Bluetooth monitoring shows voltage, capacity and charge/discharge status on your phone, and a one-touch safety switch disconnects the battery output for installation, maintenance and storage.
The metal case and internal cell holders resist road shock and vibration, and the included mounting feet let you install it directly in your RV or camper without a separate battery box.
Features
- 314Ah High-Capacity Lithium Power — about 4,019Wh of storage, roughly 12% more than the ECO WORTHY 280Ah it replaces. See ECO WORTHY 314Ah vs 280Ah.
- Metal Case — heavy-duty enclosure for heat resistance, fire protection and durability versus plastic cases.
- One-Touch Safety Switch — turns battery output off to prevent accidental discharge; switch it back on to restore power. Make sure the switch is on before using the battery or checking its voltage.
- Built-In Bluetooth Monitoring — real-time voltage, capacity and charge/discharge status in the app.
- Smart 200A BMS — 157A standard and 200A maximum continuous charge/discharge, 220A peak for 10 seconds.
- Low-Temperature Protection — stops charging in the cold to protect the cells.
- No Battery Box Required — mounting feet for direct, secure installation.
- Expandable — supports up to 4 in parallel, 4 in series, or 4P2S.
- RV & Off-Grid Ready — for RVs, travel trailers, camper vans, marine, solar storage and backup power.
Recommended Charge Settings

ECO-WORTHY recommends these solar controller settings: absorption 14.6V, float disabled (or 13.8V if your controller can't disable float), equalization disabled. See our ECO WORTHY charge settings guide for converter, DC-DC and inverter-charger settings.

ECO WORTHY 314Ah FAQ
Is this the ECO WORTHY EnergyRock 314Ah?
Yes. ECO WORTHY sells this battery as the EnergyRock 12V 314Ah metal-case LiFePO4 battery with Bluetooth and a safety switch. ECO WORTHY also makes an EnergyTrek 12V 314Ah with SOC LEDs. That is a different battery, and it isn't the one listed here.
Does the Eco-Worthy 314Ah replace the 280Ah?
Yes. It uses the same 14.6V charge settings and the same series/parallel wiring, stores about 435Wh more, and is about 0.6" longer and 0.6" taller. Don't mix 314Ah and 280Ah batteries in one bank. Full comparison: ECO WORTHY 314Ah vs 280Ah.
How many ECO WORTHY 12V 314Ah batteries can I connect?
Up to 4 in parallel, 4 in series, or 4P2S. Two 314Ah lithium batteries in parallel give 628Ah, about 8,038Wh, for a 12V RV house bank.
