PEYESTEN 20V 6.0Ah Replacement Battery Pack for Craftsman V20 Tools — 2-Pack, LED Indicator & BMS

PEYESTEN 20V 6.0Ah replacement battery is a two-pack lithium-ion power solution built to fit Craftsman V20 cordless tools and chargers, delivering higher runtime and stable output for extended job performance.

If your Craftsman 20V tools run out of juice too quickly or you need a spare set for uninterrupted work, this pair of 6.0Ah PEYESTEN batteries offers a reliable, compatible option. Each battery uses high-grade cells, includes an internal battery management system, and displays remaining charge with an LED indicator so you can plan work sessions and charging more effectively.

How long will a 6.0Ah PEYESTEN battery run my Craftsman tools?

Runtime varies by tool type and load: high-draw devices like impact wrenches and saws will deplete the pack faster than drills or lights. The 6000mAh capacity provides noticeably longer run times compared with typical 2–4Ah packs, reducing downtime for charging.

• 6000mAh capacity for extended runtime over smaller packs
• 20V nominal voltage compatible with Craftsman V20 tools
• High-current discharge design to support demanding tools

Will these batteries work with my existing Craftsman chargers and tools?

Yes — the PEYESTEN packs are engineered to be physically and electrically compatible with Craftsman V20 series tools and chargers such as CMCB104 and CMCB124. They slide into tool and charger bays like the original batteries and register with tool electronics for normal operation.

• Direct fit for Craftsman 20V V20 series cordless tools
• Compatible with standard Craftsman chargers (check model compatibility)
• Works with chainsaws, impact wrenches, saws, blowers, drills, and other V20 devices

How does PEYESTEN protect the battery and my tools?

Each pack includes a built-in battery management system that guards against overcharge, over-discharge, overcurrent and short circuits. Additionally, certified electronic protections and quality cell balancing help maintain steady voltage under load and prolong the useful life of the pack.

• BMS protects from overcharge, over-discharge and short circuits
• Cell balancing ensures consistent output across cells for better durability
• CE/FCC/RoHS certifications for electronic safety and compliance

How can I monitor charge level and handle charging conveniently?

PEYESTEN batteries include an LED dynamic display so a single press shows remaining charge at a glance. They support fast, stable charging when used with compatible Craftsman V20 chargers and help you plan swaps or charging breaks more intelligently.

• One-button LED indicator for current charge level
• Fast-charge friendly design when paired with supported chargers
• Pack of two reduces interruptions by enabling immediate tool swaps

Who is this for: The PEYESTEN 20V 6.0Ah 2-pack is designed for DIYers, tradespeople, and homeowners who need longer run times from their Craftsman V20 cordless tools without replacing chargers or tools. It’s a practical upgrade for anyone who wants a backup pair for continuous work, a higher-capacity alternative to smaller batteries, or a cost-effective way to refresh a fleet of V20 tools with reliable lithium-ion power.
