Renogy Pro S1 12V 240Ah LiFePO4 battery

Product Description

The Renogy Pro S1 12V 240Ah LiFePO4 battery packs 3,072Wh of usable-class energy into a single 12.8V deep cycle battery built on Renogy's semi-solid state cell design. With 240A continuous charge and discharge, Bluetooth and CAN communication, self-heating, and an IP67-rated housing, it is built for demanding mobile and off-grid systems that need serious capacity from one battery.

Who This Is For

The Pro S1 240Ah fits RVs, campervans, and boats that want high capacity without wiring multiple batteries, plus off-grid cabins that need dependable storage through cold seasons. Its 240A continuous discharge can carry a large 12V inverter on its own — for example, a 3,000W unit such as the Renogy REGO 3000W 12V split-phase inverter charger draws roughly 250A at full load, which stays within this battery's rating.

Key Features

  • 240Ah rated capacity at 12.8V nominal — 3,072Wh of energy in one battery
  • Semi-solid state cells reduce liquid electrolyte by approximately 70% compared with conventional lithium-ion designs, per Renogy
  • 6,000-cycle rating at 80% depth of discharge, per Renogy
  • 240A maximum continuous charge and discharge; 450A peak discharge for 30 seconds, per Renogy
  • Self-heating supports charging in temperatures down to -4°F, with up to 70% faster recovery from low-temperature protection, per Renogy
  • Bluetooth (range up to 32.8 yd, per Renogy) and CAN communication for monitoring
  • Intelligent Power Armor staged overcurrent protection: 165A/1 min, 240A/30 s, 360A/200 ms, per Renogy

Why Renogy

Renogy engineers batteries, inverters, and charging equipment as a matched ecosystem, and the Pro S1 line is its current-generation flagship battery platform. OffGrid Horizon is a family-owned authorized Renogy dealer, so this battery carries Renogy's full US warranty.

What Semi-Solid State Means

Per Renogy, the Pro S1's cells replace roughly 70% of the liquid electrolyte found in conventional lithium-ion batteries with a semi-solid design. Renogy states this construction shows a temperature rise up to 9 times slower than traditional liquid-electrolyte lithium batteries under stress, and it pairs the cells with staged overcurrent protection and a self-controlled fuse. The practical takeaway: a battery designed with additional layers between an electrical fault and a thermal problem.

Frequently Asked Questions

Can I connect multiple Pro S1 batteries?
Yes. Per Renogy, the Pro S1 supports connection up to 4S4P — series strings for higher-voltage banks and parallel strings for more capacity. Follow the user manual for approved configurations and cabling.

How do I monitor the battery?
The battery has built-in Bluetooth with a range of up to 32.8 yd per Renogy, plus a CAN port for system communication. You can check battery status from your phone through Renogy's app.

Does it really charge below freezing?
Yes. Per Renogy, the charge temperature range is -4°F to 131°F, and self-heating recovers the battery from low-temperature protection up to 70% faster than previous designs.

What inverter size can one battery support?
With 240A continuous discharge, one battery supports roughly 3,000W of inverter load at 12V. The REGO 3000W inverter charger linked above is a natural pairing.

How is this different from a standard LiFePO4 battery?
The semi-solid state cells use about 70% less liquid electrolyte per Renogy, and the battery adds staged overcurrent protection, a 6,000-cycle rating, and an IP67 housing — features aimed at harsher duty than entry-level lithium batteries.

Is a 300Ah alternative available?
Yes — if you prefer Renogy's Core series, see the Core 12V 300Ah self-heating battery.
