This SkyRC NC2200 AA/AAA battery charger-analyzer charges up to 4 batteries at once, so you can quickly power your electronic devices. The visual charging status keeps you informed on when your batteries are ready for use. It can handle 1 to 4 AA and AAA NiMH/NiCD rechargeable batteries via four independent charging slots with its respective interface. With the wide-viewing VA screen, the charger displays Current, Capacity, Internal Resistance, Voltage, Elapsed Time, and working mode at a glance. Meanwhile, the charging graph and firmware upgrading can be accessible with the SkyCharger app if you connect the optional Bluetooth Dongle.

The Cortex-M3 processor is specifically developed for high-performance, cost-effective platforms for various devices, including microcontrollers, automotive body systems, industrial control systems, and wireless networking and sensors. Thanks to Cortex-M3 by ARM, NC2200 can complete real-time acquisition of battery voltage and current, and the charging process under intelligent control. It can automatically calculate the remaining charging time of the battery and adjust the parameters. System management circuit also has a protective function, which can prevent damage to the battery from overcharge and overtime.

NC2200 comes with five operation modes: Turbo(fast charge), Charge, Discharge, Refresh & Analyze and Break-in. With these five modes, you can charge, optimize your battery, and even you can rescue the battery from dying. The internal resistance of the battery usually increases as it is used. Then the battery is used for a long time, its internal resistance will increase. The internal resistance consumes part of the electric energy when charging and causes the battery to heat up simultaneously. SkyRC deploys an innovative FlexiPulse algorithm for internal resistance detection in this charger. Once a high internal resistance is detected, the charge current will automatically decrease to reduce the overall heating and protect the battery.

Most electronic devices usually require two or more batteries to be used together. In this circumstance, the overall performance will be limited by the worst battery. In other words, the poorly performing battery will affect the operating time of the device. We can understand battery matching as group batteries with similar actual capacity. Grouping batteries by similar capacity will maximize the battery series' efficiency. You can group batteries easily in the Refresh mode! The battery formatting refers to activating the battery with a small charge and discharge rate in a charge-discharge-charge sequence. With NC2200, battery formatting can be done in Break-in mode. In some circumstances, this process may need to be repeated two to three times.

NC2200 will start working automatically to the last remembered setting if the charger worked once and its power uninterrupted. Then programming in 5 modes, you apply one slot's setting to all the rest slots, PRESS & HOLD the ENTER button for two seconds.

You can view NC2200 via your smartphone via the optional Bluetooth dongle. The free SkyCharger app gives you a more intuitive experience: all data is displayed at a graphic interface with a charging graph! With the recorded data on the app, you can easily analyze your battery's performance!
