DTK Replacement for EGO 56V Battery BA1400 BA2800 BA4200, 56 Volt 2.6Ah Batteries Lighter Than 5AH (Easy to Carry, and not Tiring)

What It Is

This is an aftermarket 56-volt, 2.6Ah lithium-ion battery designed as a lighter-weight replacement for EGO’s BA1400, BA2800, and BA4200 packs. It’s intended for EGO 56V cordless lawn mowers, trimmers, blowers, and other tools in the ARC/LPX line, where a compact, less fatiguing battery is preferred for quick jobs or for users who want to reduce overall tool weight.

Fitment & Compatibility

Before buying, confirm your tool uses EGO’s 56V ARC/LPX battery interface (all EGO 56V tools are compatible, but check the battery port shape). This battery is not compatible with EGO’s 56V backpack or commercial-series tools, nor with 82V or 40V platforms. Measure the battery compartment on your mower or tool: this pack is physically smaller than the 5Ah, so it fits most standard slots, but verify the release latch alignment (EGO’s spring-loaded latch design is standard). It will not work with older 56V tools that require a “tower-style” battery (pre-2015 models). Always cross-check the OEM part number: BA1400, BA2800, or BA4200.

Key Things to Know

• Weight vs. runtime: At 2.6Ah, this battery is roughly 1.2 lbs lighter than a 5Ah pack, but runtime is about half. Expect 20–30 minutes on a push mower with a 20-inch deck, less on high-power blowers.
• Charging: Use your existing EGO 56V charger (CH5500, CH2800, etc.). The aftermarket battery may charge slower than OEM due to internal BMS differences.
• Build quality: User reviews note inconsistent cell quality—some packs fail within 6 months. The plastic housing is thinner than OEM, so avoid dropping.
• LED indicator: Has a 4-bar charge gauge, but accuracy varies. Fully charge before first use.

Should You Buy It

This is a good budget option if you want a backup battery for light-duty trimming or mowing, or if you need a lighter pack for a smaller-framed user or elderly operator. Avoid it if you need maximum runtime for large lawns, or if you rely on the battery for daily commercial use—the OEM 5Ah or 7.5Ah will be more reliable and last longer.
