LiPo Battery 1300 mAh 7.4 V 25C Mini Tamiya

Introduction to Li-Po Batteries

Lithium-ion-polymer (LiPo) battery packs are the advanced successors to the well-established lithium-ion (LiIon) battery packs. The primary advantage of LiPo batteries is their exceptional capacity-to-size ratio. Despite their compact size, they maintain a high current capacity, making them suitable for virtually any AEG replica. Additionally, LiPo batteries do not suffer from the memory effect, allowing them to be charged frequently without the need for complete discharge beforehand. In fact, frequent charging is advantageous for this type of battery.

Usage and Maintenance Guidelines

• Discharge and Charge Limits: It is crucial to ensure that a LiPo pack is not discharged below 3V per cell and not overcharged beyond 4.2V per cell.
• Self-Discharge Rate: LiPo packs exhibit a low self-discharge rate, losing approximately 3-5% of their energy per month when not in use. However, it is essential to monitor the pack during extended storage periods to prevent discharge below the permissible minimum value (3V per cell), which could lead to irreversible chemical reactions and potential damage, including the risk of ignition.
• Storage Charge Level: An unused LiPo pack should ideally be maintained at an average charge level of approximately 70%.

Performance and Longevity

When properly used, LiPo battery packs typically have a lifespan of 500-700 cycles. A significant factor influencing 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 optimal condition, it is recommended to balance LiPo batteries during charging using a service plug, which is a feature present in most LiPo packs. A quality LiPo charger will include a built-in balancer to facilitate this process.
