The P26A from Molicel is a very good all-round cell in the 18650 size. Judging by the tests, it is even better than the Sony/Murrate US18650 VTC5A. Suitable for moderate to high power consumption, the Molicel is the best choice when it comes to safety.
The Molicel are only sold through authorised dealers and unlike other manufacturers are officially allowed to be used in e-cigs.

Molicel INR18650-P26A with solder tag U

Molicel was founded in 1987 from a Lithium Ion research group and is 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.

This high current cell can be used with a constant load of 35A with temperature control up to 80°C.
Current draw up to 70A pulse is realistic for the cell.

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 INR18650-P26A with solder tag U - 2600mAh, lithium-ion battery.

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.
