High quality two-piece, High Performance 7.4V 2000 mAh 25/50C lithium polymer battery (LiPo).
LiPo batteries in a nutshell:
- Batteries are delivered approx. 30% charged and tested
- Batteries should be stored at approx. 30% (3.85V/cell) charge level
- During long-term storage, batteries should be charged slightly every 3-6 months.
- Batteries self-discharge at a rate of approx. 5% per month
- It is recommended to store batteries in a dry and cool place
- Batteries should not be stored fully charged for long periods of time.
- Batteries must not be discharged too far. Recommended minimum 3.0V and preferably 3.2V /cell. Absolute minimum 2.75V/cell
- The lifespan of the batteries is approximately 3 years if handled properly, but high discharge currents shorten the lifespan.
- C-value (ability to deliver current) decreases as the battery ages
- Maximum currents are usually stated as continuous and instantaneous, e.g. 25/50C
- You can get the discharge current by multiplying the battery capacity by the C value.
- Full power is often only achieved from a new LiPo battery after a few charge and discharge cycles.
- LiPo batteries are safe when used correctly
- Because the cells have a high energy-to-volume ratio, improper charging or short circuiting can cause a fire.
- Do not use the LiPo battery if the cell(s) are clearly bulging or otherwise damaged.
- Send the defective LiPo battery for recycling
Charging the LiPo battery:
- Only use a charger designed for Lithium-polymer (LiPo) batteries.
- Only charge with a charger equipped with a balancer, which balances the cells during charging
- Make sure the charger settings are correct. Incorrect settings may cause a fire.
- Charge and store batteries in a fire-safe place
- Place the batteries in a protective bag, for example a LiPo bag, while charging.
- Make sure there are no flammable materials nearby
- Always monitor the battery charge
- Never leave batteries charging overnight
- Never charge batteries with too high a charging current
