24V 100Ah LiFePO4 Lithium Iron Phosphate Battery — Deep Cycle for Solar, RV & Marine

The Battery That Lasts a Decade.

LiFePO4 (Lithium Iron Phosphate) is the battery chemistry that changed off-grid power. It lasts 2000–5000+ charge cycles — compared to 300–500 for lead-acid — which means a battery that pays for itself many times over its service life. This 24V 100Ah unit delivers 2400Wh of usable energy storage with a built-in BMS that protects against every failure mode that kills lesser batteries. Drop it into a solar system, an RV, a boat, or any 24V application and expect it to still be working a decade from now.

Features

• 24V 100Ah capacity — 2400Wh of total energy storage; approximately 2280Wh usable at 95% depth of discharge
• LiFePO4 chemistry — Lithium Iron Phosphate cells offer 2000–5000+ charge cycles, superior thermal stability, and no thermal runaway risk
• Built-in BMS — Battery Management System protects against overcharge, over-discharge, over-temperature, short circuit, and cell imbalance
• High continuous discharge rate — supports high current draw for running inverters and high-power loads
• Lightweight vs. lead-acid — significantly lighter than an equivalent 24V lead-acid battery for the same usable capacity
• Low self-discharge — retains charge for months in storage without significant capacity loss
• Wide temperature range — operates in a broad temperature range; check variant for low-temperature charging limitations
• Parallel & series compatible — connect multiple batteries in parallel for more capacity or in series for higher voltage systems

Who It’s For

• Solar system builders who need a reliable 24V battery bank
• RV and van lifers running 24V electrical systems
• Boaters who need lightweight, high-cycle marine battery storage
• Off-grid cabin and tiny home owners who need long-lasting energy storage

How to Use

1. Connect to a 24V solar charge controller and solar panels for off-grid charging.
2. Connect to a 24V AC charger for wall charging.
3. Connect a 24V inverter to the battery terminals for AC power output.
4. Monitor state of charge via the built-in display or a battery monitor.
5. Do not charge below 0°C (32°F) without a low-temperature BMS — check variant specs.

Frequently Asked Questions

How does this compare to a 24V lead-acid battery?
A 24V 100Ah LiFePO4 battery provides approximately 95Ah of usable capacity. A 24V 100Ah lead-acid battery provides only 50Ah usable (50% DoD). LiFePO4 also lasts 5–10x longer in cycle life and weighs significantly less — making the higher upfront cost cost-effective over the battery’s lifetime.

Can I connect two batteries in parallel for 200Ah?
Yes — connect two identical 24V 100Ah batteries in parallel (positive to positive, negative to negative) to double the capacity to 200Ah at 24V. Ensure both batteries are at the same state of charge before connecting.

What size inverter can I run from it?
Check the battery’s maximum continuous discharge current (amps). Multiply by 24V to get maximum inverter wattage. For example, a 100A continuous discharge rate supports a 2400W inverter at full load.
