Molicel P28A 18650 Battery Applications

1. Power Tools: This battery cell is specifically designed for high-power tools such as electric drills, chainsaws, impact wrenches, angle grinders, and hammer drills. A continuous 35A discharge capacity ensures instantaneous high-current output, meeting the power demands of start-up impacts and heavy-duty conditions; low internal resistance reduces temperature rise during high-current discharge, ensuring stability and safety during continuous operation.

2. Garden Tools: Suitable for outdoor power equipment such as cordless lawnmowers, hedge trimmers, chainsaws, leaf blowers, and lawn mowers. A -40℃ low-temperature discharge capability allows for reliable start-up and operation in cold seasons or low-temperature regions; a 2800mAh capacity provides sufficient battery life for a single operation, and combined with high-rate discharge capability, it can handle continuous high-load scenarios such as lawn mowing.

3. Home Appliances: Used in cordless home appliances such as cordless vacuum cleaners, robot vacuums, and handheld cleaning machines. High energy density and long cycle life meet the needs of high-frequency daily use; high-rate discharge ensures the absorption of large currents during startup in vacuum cleaners and other devices, while maintaining stable power output throughout the cleaning cycle.

Other Applications: This battery cell is also widely used in electric bicycles/scooters, model drones, high-brightness flashlights, robots, portable energy storage systems, and DIY battery packs—devices requiring high-rate discharge and high reliability.

Application and Safety Tips: This battery cell features an unprotected flat-top design, primarily intended for battery pack integration applications. It must be used with a BMS (Battery Management System) or protection board to avoid overcharging, over-discharging, short circuits, and extreme high-temperature environments. It uses the standard CC-CV charging method; a dedicated lithium-ion charger is recommended.

Custom configurations, including PCM/BMS protection circuits, connectors, and cable options, are available to ensure safe integration into your specific product requirements.
