The exceptionally powerful 21700 industrial high current cell meets or exceeds most round cells on the market (as of 2023).

Molicel 21700 high current cell with 4500mAh and up to 45A constant load.

Designed for applications such as: impact hammer, industrial battery vacuums, gardening tools, etc. Excellent for applications such as powerful RC models, battery carriers, MTB Enduro or Dunhill e-bikes.

This high-current cell can be used with a constant load of 45A up to 80°. Current draws of up to 90A pulse for approx. 3s are realistic with this cell.
Excellent charging characteristics up to 9A enable rapid charging of the cell.

Technical data of the Molicel INR21700-P45B

Molicel was founded in 1987 from a research group working on lithium-ion. Molicel was one of the pioneers of the lithium-ion industry. Molicel batteries are used wherever extreme operation and high reliability are required, customers include NASA, DASA, Dyson, Boeing, etc.

Safety instructions:

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised specialist personnel.
Incorrect handling or short-circuiting may result in fire or explosion.

Further characteristics:

Lithium-ion batteries are thermally stable and are not subject to any memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Scope of delivery:

1x Molicel INR21700-P45B - 4500mAh, lithium-ion rechargeable battery.

Notes on use and distribution.

The industrial cells are intended for further processing.

Notes:

Charging lithium-ion batteries requires a special charger that charges the batteries according to a special charging procedure (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or the number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, the cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a small charging current, which can be dangerous.

Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law in the municipal collection points or in the [usually green] containers provided by retailers.
