2Pack 56V 5000mAh BA2800 Battery Replacement for EGO 56V Battery 5.0Ah Compatible with EGO 56 Volt 5000mAh BA2800 BA4200 CS1604 CS1804 CS1403 HT2400 LB6504 LB5804 LB6500 LB4800 Power Tool(5.0Ah)

What It Is

This is a 2-pack of 56V 5.0Ah lithium-ion batteries designed as a replacement for EGO’s BA2800 and BA4200 power tool batteries. It’s intended for EGO 56-volt lawn mowers, string trimmers, leaf blowers, chainsaws, and hedge trimmers that accept the ARC-Lithium battery platform.

Fitment & Compatibility

Before buying, confirm your EGO tool uses the ARC-Lithium battery interface (most 56V EGO tools do). This pack is compatible with models like the LM2100, LM2101, LM2102SP mowers, LB6504, LB5804 leaf blowers, CS1604, CS1804 chainsaws, HT2400 hedge trimmer, and many others. Measure your battery compartment: the BA2800 is roughly 7.5 x 4.5 x 4 inches. If you have a newer EGO tool that requires a “Power+” or “Peak Power” battery, this standard 5.0Ah pack will still work but won’t deliver the extra burst power of a 7.5Ah or larger battery. This is an aftermarket replacement—not OEM EGO—so check that the terminal alignment and release button match your tool’s cradle.

Key Things to Know

• Quality variance: Aftermarket batteries may have slightly lower capacity than OEM EGO 5.0Ah packs and can degrade faster with heavy use. Read recent reviews for your specific tool.
• Installation: Drop-in fit—no tools needed. Just slide into the battery slot until it clicks. If it doesn’t seat fully, check for debris or bent terminals.
• Charging: Use only EGO 56V chargers (CH5500, CH2800, etc.). Third-party chargers can damage the battery or cause fire risk. Charge time is ~60-90 minutes per battery.
• Common gotcha: Some users report the battery gauge LEDs are less accurate than OEM. Test immediately to ensure all 4 bars light up when fully charged.

Should You Buy It

Buy this 2-pack if you own multiple EGO 56V tools and need a budget-friendly backup for lighter tasks like trimming or blowing. It’s a decent value for the price, but if you rely on your mower for a large lawn or need maximum runtime, stick with OEM EGO BA2800 batteries for better longevity and warranty support.
