Introduction to LiPo Batteries

Lithium-ion-polymer (LiPo) battery packs are the advanced successors to the well-established lithium-ion (LiIon) packs. The primary advantage of LiPo batteries is their exceptional capacity-to-size ratio. These batteries are compact yet maintain a high current capacity, making them suitable for nearly every AEG replica. Additionally, they do not suffer from the memory effect, allowing for frequent charging without the need for complete discharge beforehand. This frequent charging is advantageous for maintaining the battery's performance.

Usage and Maintenance Guidelines

• Ensure that a LiPo pack is not discharged below 3V per cell and not overcharged beyond 4.2V per cell.
• LiPo packs exhibit a low self-discharge rate, losing only about 3-5% of their energy per month when not in use.
• During extended storage, monitor the pack to prevent discharge below the permissible minimum value of 3V per cell, as this can lead to irreversible chemical reactions and potential damage, including the risk of ignition.
• For optimal storage, maintain an average charge of approximately 70% in an unused LiPo pack.

Performance and Longevity

When used correctly, LiPo battery packs typically last between 500 to 700 cycles. A critical factor in their performance is the operating temperature. Unlike other battery types, LiPo cells function effectively at low temperatures; however, they should be charged at room temperature. To ensure the longevity and optimal condition of LiPo batteries, it is essential to balance them during charging. This can be achieved using the service plug available on most LiPo packs, and a quality LiPo charger with a built-in balancer is recommended.
