Why choose this product?

• Clearly defined dimensions for structural design
• Capacity and voltage suitable for compact electronics power supply
• Parameters suitable for normal Li-Pol charging mode (CC/CV at 4.2 V)

Installation and operating instructions

• Charge only with a charger/controller designed for Li-Pol (1S) with a terminal voltage of 4.2 V.
• Observe the polarity of the wires: the red wire is the positive pole (+), the black wire is the negative pole (-).
• When designing the device, consider the 1C discharge current and the corresponding current load of the wires and connections.

Safety notice

• Do not overcharge above 4.2V and do not discharge below the safe voltage recommended for Li-Pol cells; use appropriate protection (BMS/protection circuit) according to the application.
• Do not short-circuit, puncture, deform, or expose the battery to high temperatures.
• Install in such a way that there is no mechanical stress on the housing or wires.
