Developed for industry, e-bikes, LEDs, model making and mobile applications.
The INR18650-M26 is a typical e-bikes cell, with max. 10A discharge current, the cell is also ideally suited for E-MTB.
Please note: The industrial cell does not have an integrated electronic protection circuit PCB/BMS and does not have sufficient insulation for normal household use (e-cigarettes, flashlights, etc.) and is missing labels. The industrial cells are designed for further processing into battery packs or integrated, permanently installed use.
For use in e-cigarettes or e-shishas, we at Keeppower have sufficiently insulated cells labeled with important key figures that are suitable for use in devices equipped exclusively with protective electronics.
Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by qualified personnel.
Incorrect handling or short-circuiting may result in fire or explosion.
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.

Notes:
A special charger is required for charging lithium-ion batteries, which charges the batteries according to a special charging procedure. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.35 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.2 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 at the municipal collection points or in the [usually green] containers provided by retailers.
