The IMAX B3 Pro is a simple and reliable balancing charger for 2S (7.4V) and 3S (11.1V) Li-Po and Li-ion batteries featuring a JST-XH connector. Thanks to its built-in switching power supply, it connects directly to a 100–240 V mains supply and does not require an additional adapter.
The charging process is controlled by a microprocessor, which ensures the correct balancing of each battery cell. For ease of use, there are three two-color indicators:
✅red — battery is charging;
✅green — charging is complete.
IMAX B3 Pro is a compact solution for owners of drones, quadcopters, radio-controlled airplanes, helicopters, cars, boats, and airsoft drives that use Li-Po or Li-ion batteries.
