2Pack 10000mAh BA2800 Replacement for EGO 56V Battery Lithium Replacement for EGO 56 Volt Battery 10.0Ah Conpatible with EGO 56 Volt BA4200 CS1604 CS1804 CS1403 HT2400 Power Tools (10.0Ah, 2Pack)

What It Is

This is a 2-pack of 10.0Ah (10000mAh) replacement batteries for EGO 56V power tools and lawn equipment. Designed as a higher-capacity alternative to the OEM BA2800 (2.5Ah) and BA4200 (4.0Ah), it’s intended for extended runtime on mowers, trimmers, blowers, chainsaws, and hedge trimmers.

Fitment & Compatibility

• Brand/Model: Compatible with all EGO 56V tools that use the ARC-Lithium slide-on battery platform. This includes mowers (e.g., LM2100, LM2101), string trimmers (e.g., ST1500, ST1623T), blowers (e.g., LB5300, LB6150), chainsaws (e.g., CS1604, CS1804, CS1403), and hedge trimmers (e.g., HT2400).
• OEM vs Aftermarket: This is a third-party replacement, not an official EGO product. It will physically fit the battery port and latch, but may not communicate with the charger/tool’s battery management system (BMS) as seamlessly as an OEM battery.
• What to Check: Verify your tool’s battery port is the same slide-in style as EGO’s standard 56V batteries. Measure the battery compartment on your mower or tool—this 10.0Ah pack is larger than a BA2800 (roughly 7.5” x 5” x 4.5”). It may not fit under the seat/hood of some older or compact EGO mowers. Check for clearance.

Key Things to Know

• Capacity vs Weight: At 10.0Ah, this pack is significantly heavier (approx. 4 lbs each) than a 2.5Ah battery. This adds noticeable weight to handheld tools like trimmers or blowers.
• Charging Time: Expect longer charge times—up to 3-4 hours on a standard EGO charger (e.g., CH5500). A fast charger (CH2100, CH3200) will reduce that to ~1.5-2 hours.
• BMS Compatibility: Third-party batteries may not trigger the tool’s low-battery warning or charge indicator lights correctly. You might see LEDs not lighting up or the tool cutting out earlier than expected.
• Warranty: The seller likely offers a 1-year warranty, but EGO will not cover damage caused by aftermarket batteries. If your tool fails, EGO may deny service if a non-OEM battery is used.

Should You Buy It

Buy this if you need maximum runtime for a large lawn (over 1/2 acre) and are comfortable with aftermarket electronics—especially if you already own multiple EGO tools and want to share batteries. Skip it if you value precise charge status, tool compatibility with EGO’s BMS, or if your mower has a tight battery compartment that won’t fit the larger pack. For light use or small yards, a single OEM BA4200 or BA2800 is simpler and more reliable.
