High safety, environmental compatibility and cycle stability speak for LiFePo4 cells. A high-quality cell developed by Sony with a long service life and very high cycle stability. Service life 10x longer than Li-Ion batteries with approx. 6000 charging cycles.

Sony US26650FTC1 LiFePo4 Lithium Iron Phosphate Battery + Solder Tag Z Shape.

Fields of application: Solar lamps, renewable energy storage and mobile applications.

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 can lead to fire or explosion.

Other features:

Lithium iron phosphate 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.
Power density up to 3000 W/kg, higher than the conventional Li-Ion battery based on LiCoO2, thus high load capacity (continuous current draw).

Note:

A special charger is required for charging lithium iron phosphate 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 3.6 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 3.5 volts, as this significantly increases the service life or the number of charging cycles (possibly up to double). Only lithium chargers may be used for charging. Only lithium chargers with a charge of up to 3.6V may be used for charging. e.g.: XTAR VP2, XTAR SP1, XTAR WP2H, Nitecore D4,

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.
