With the experience of more than 10 years of IT services, E-Stream Energy has been active in the field of renewable energies since restructuring in 2016 and has entered the development of versatile high-performance energy storage systems for stationary and mobile applications. The German-based company with several locations brings high-quality products to the market that do not compromise on quality, performance, safety and reliability while taking costs into account.

The ES 18650-29EP Li-NMC with 2900mAh and max. current output of 10A (constant).

The high cycle stability makes it 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 from well-known manufacturers have to make do with 70 - 80 % of their capacity after 1000 cycles, the E-Stream cell still achieves an excellent 87.5 % of its capacity.

Technical data of the E-Stream ES18650-29MP

Comparisons, discharge curves and test runs:

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

Test report

Safety instructions:

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

Further characteristics:

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

Scope of delivery:

1x E-Stream ES18650-29MP - 2900mAh, lithium-ion rechargeable battery.

*Other options:

- No selection: battery cell without options as in the main picture.
- Raised positive terminal: A 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 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, as 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.
