ISDT C4 EVO Battery Charger Smart Rapid Charger Mini 4WD Lipo NiMH 18650 RC Drone Quadcopter Please update the firmware to 1-6S AA/AAA AA/AAA

Automatically detects the type of [Professional Smart Charger] and sets the optimal charging/discharging mode. (Manual operation is also possible). In addition to charging, discharging, and cycle charging and discharging, it is also possible to activate with aperture discharge and refresh functions. [4 independent slots] Up to 4 channels can be operated independently, such as charging lithium ions in slot A and discharging nickel metal hydride in slot B at the same time. The charging current value of each slot is 0.1~3A, and the discharging current value is 0.1~1.5A. [Compatible with a variety of devices] Not only is it compatible with the mainly used AA/AAA, NiCd/NiMH, but also NiZn (nickel zinc) and lithium ion. Make everything smart. Supports AAA, AA, 10440, 10500, 12500, 13500, 14500, 14650, 16650, 17650, 17670, 18650, 18700, 20650, 20700, 21700, 22650, 26650, 26700. (Since the total length of the 18650 standard slot is fixed, batteries with large internal safety circuits may not fit.) [Power input via USB Type-C] Maximum 36W, DC5~12V, supports QC2.0/3.0 and PD. A 5V -1A power supply can also be used as an input power source (however, the charging current value cannot be set high). USB-C cable included *This charger does not include a power supply. Please prepare a Type-C power supply. 5~12V, max 36W (supports QC, PD protocols). [Small and lightweight] Compact size, almost the same as a passport at 120 x 92 mm, and weighs only 153g (excluding AC adapter). Convenient to carry and store. [Reliable 365-day Manufacturer's Warranty] We offer a 12-month manufacturer's warranty from the date of purchase and reliable after-sales service. If you have any questions or concerns, such as damage, defacement, missing accessories, etc., please feel free to contact us. Considering charging efficiency, we recommend using an adapter of 9V/2A or higher. Please update the firmware to V1.0.0.44. Extended mode discharges and then charges, which can cause voltage sags. Accessories: AC adapter, protective film, English version instruction manual.
