Features:
1. Ultra-long service life (the capacity is not less than 80% after 2000 cycles);
2. Excellent working temperature (it can operate stably under -20℃～+60℃ temperature conditions for a long time); especially suitable for high temperature and severe conditions;
3. Installing a battery detection unit in the battery pack can accurately detect battery voltage, temperature, capacity, and other conditions in real-time, and transmit it to the drone through the communication system in time, which can fully improve the safety of the product's work;
4. The battery pack shell is designed with alloy materials, with superior impact resistance and high and low-temperature resistance, effective flame retardant high performance, which can ensure that the battery pack always maintains effective protection ability under the external impact. The exterior is equipped with a folding handle. Easy to carry;
5. Simple installation and combination (the design concept of the unit module makes the product installation flexible and reliable);
6. With RS485 communication output and remote monitoring; reading voltage, remaining capacity, current, and other information, data uploading for remote monitoring, after-sales service will find and solve problems in advance.
7. It complies with the standards of the communications industry and lithium-ion batteries for electric vehicles. It can be directly assembled with the cabinet, and the products can be used in parallel.
