For pilots who need record charging speeds in the field, the ISDT MA331 Air charger is created. This is a new generation high-power charging station in a rugged, compact case. It allows you to charge LiPo and Li-ion batteries at incredible speed. You will reduce downtime between flights to an absolute minimum. The device is powered by external sources such as a battery or power supply. This is a professional tool for winning competitions and effective filming.

Charger ISDT MA331 Air is synonymous with speed and reliability. Its power of 331W speaks for itself. You will be able to charge the most capacious 6S batteries at maximum current. Active balancing ensures battery safety and longevity. The durable metal housing effectively dissipates heat. This is a choice for those who value every second and do not compromise on preparation. Your batteries will be ready for your next flight faster than the competition.

Five main advantages of the device

• High power 331W for ultra-fast charging. Allows the use of maximum currents for high-capacity batteries. You will spend much less time charging.

• Active balancing for maximum safety. Advanced technology for redistributing energy between cells. Guarantees perfect balance and extends the life of LiPo.

• Compact and durable metal housing. Built for the rigors of field flights. Takes up minimal space in your field kit.

• Supports LiPo and Li-ion batteries up to 6S. Works with most racing and freestyle drone batteries. From 2S to the most powerful 6S builds.

• Informative color display and simple operation. The clear screen shows all the details of the charging process. Quickly adjust parameters even under stressful conditions.

Operating principle and technical details

Charger ISDT MA331 Air Works as a high-precision power supply with an intelligent controller. Its powerful switching converter accepts input voltage (eg 24V). It then converts it into precise charging parameters with high efficiency. For LiPo batteries, the CC/CV (constant current/constant voltage) algorithm is used.

The device supplies constant current until the battery voltage reaches its peak. Then it switches to constant voltage mode, gradually reducing the current. All magic happens thanks to active balancing. It works in real time, pumping energy between cells. This is faster and more efficient than simply discharging the leading banks. ISDT MA331 Air also monitors temperature and internal resistance. This allows the process to be optimized for a specific battery condition.
