Molicel INR21700-P42A 4200mAh 45A Li-ion Cell
Molicel INR21700-P42A is a high-drain 21700 Li-ion cell with a capacity of 4200 mAh and a maximum continuous discharge current of up to 45 A. The P42A combines high capacity with excellent current performance, making it ideal for devices that require high power output and a stable power supply.
The Molicel P42A 4200mAh 45A cell can be used for building and rebuilding Li-ion battery packs, including batteries for electric bikes, electric scooters, power tools, and other devices requiring high-drain 21700 cells.
Power Tool Applications
Thanks to its high current capability, the Molicel INR21700-P42A cell can be used for building and rebuilding power tool battery packs. The cell can be used in batteries for power tool brands such as Bosch, Makita, DeWalt, Milwaukee, Metabo, Ryobi, and Einhell, provided that the cell specifications are compatible with the design of the battery pack and its BMS.
High-Drain Molicel 21700 Cell
The Molicel INR21700-P42A is designed for applications where both high capacity and high current output are required. With a maximum continuous discharge current of up to 45 A, this cell is well suited for building powerful and efficient battery packs.
The 21700 format provides high capacity per cell while maintaining excellent high-current performance. The Molicel P42A is a great choice for electric bike batteries, electric scooter battery packs, power tool batteries, and other devices with high power requirements.
Important Information
The Molicel P42A does not have a built-in electronic protection circuit. When building battery packs, a suitable BMS (Battery Management System) must be used and correctly matched to the number of cells, battery voltage, and maximum operating current.
Li-ion cells should only be assembled into battery packs by people with appropriate knowledge and experience. Spot welding is recommended for connecting cells. Direct soldering to the cell terminals is not recommended.
Before connecting cells into parallel groups or assembling a battery pack, check and balance their voltages. Only use chargers designed for lithium-ion cells and never exceed the specified operating parameters.

Maximum discharge current in batteryMore
The discharge current when working in packs (a battery composed of many 18650 or 21700 cells) is lower than the current specified in the catalog note for one cell. This is due to the fact that many cells in the pack heat up from each other. The increased and uneven temperature of the pack causes rapid degradation of the cell and such a battery may not survive even one season. For the safety and long life of your battery, always design it safely based on the maximum operating current in the pack. Do not overload the cells, do not build a pack based on the maximum current for 1 cell - otherwise your pack will have a very short lifespan.
