The company E-STREAM, which already has several locations in Germany, is engaged in the development and production of high-quality energy storage systems. In order to bring high-quality products to the market, it is imperative not to compromise on quality, performance, safety and reliability while taking costs into account.

The ES 18650-26EP Li-NMC with 2600mAh and max. current output of 15A (constant)

The battery cell developed for highest requirements is suitable for all applications up to 15A discharge current. Due to its high cycle stability, it is particularly suitable for use in e-mobility and stationary storage systems.

The 18650 Li-Ion cell reaches an excellent 70% of capacity after 2000 full cycles.

Whereas most Li-Ion batteries have to make do with 80% of their capacity after 300 cycles, the E-Stream cell still achieves a fantastic 92% of its capacity.

Technical data of the E-Stream ES18650-26EP

Comparisons, discharge curves and test runs:

https://www.lygte-info.dk  "It is not a very high capacity battery, but it copes well with high discharge current.
It is interesting to see the cycle specifications for different current loads, the capacity decreases only slightly at higher current and the life is very long at low current and slow charging.)

Safety instructions:

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised qualified 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 E-Stream ES18650-26EP - 2600mAh, lithium-ion battery.

* POST SEPARATELY The official shrink tube has been changed, confusing information on the battery 7.5A is the recommended discharge current.

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 4.2 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 at the municipal collection points or in the [usually green] containers provided by retailers.
