Detailed Insights

Battery Specification

Replace your old battery with a 21V 4000mAh Li-ion battery that comes with a battery level indicator. Easily monitor the battery level at any time to decide when to charge.

High Capacity

This battery boasts a 4000mAh high capacity, ensuring longer working hours. For instance, when fully charged, it can support spraying up to 10 to 12 pots of 900ml paint. Charging takes about 3 to 4 hours.

Wide Compatibility

Designed primarily for the WANGMI cordless electric paint sprayer PSBD-CS021DB, this battery is also compatible with most electric tools that use similar interfaces.

Multiple Protection

Our battery features built-in overcharging, over-discharging, over-voltage, over-current, and over-heating protection. No memory effect means you can charge or discharge as needed without losing capacity.

Kind Reminder

Avoid placing the battery in damp areas or direct sunlight. Store it away from heat sources and recharge it every 3 months during storage to maintain optimal performance.
