Molicel was founded in 1987 from a lithium ion research group and 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.

Molicel 21700 high current cell with 4200mAh and up to 45A constant load

This high current cell can be used with a constant load of 30A or up to 45A with 80°C temperature monitoring.
Current draw up to 70A pulse is realistic for this cell.

Datasheet:

INR21700-P42A

Safety instructions:

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised specialists.
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-P42A - 4200mAh, lithium-ion rechargeable battery.

Notes on use and distribution.

The industrial cells are intended for further processing.

*Other options:

- No selection: battery cell without options as in the main picture.
- Raised positive terminal: Button (nipple) welded to the positive terminal by means of a special welding process raises the flat positive terminal by approx. 2 mm, similar to e.g. a normal battery (for an additional charge).
- Solder tag: A metal tongue (W: 7mm x L: 25mm x D: 0.15mm), which is firmly connected to the battery at the plus and minus pole and is used to solder a connecting wire or further batteries to the component (at an extra charge).
U - Both solder tags point in one direction (e.g. for parallel connection or soldering to electronic components).
Z - Solder tags point in opposite direction (e.g. for series connection or soldering to electronic components).

Notes on use and distribution.

The industrial cells are intended for further processing, (marking of the cells for B2C is not sufficient).

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.
