HEDBOX RP-DC40 Battery Charger
The RP-DC40 digital LCD battery charger conveniently charges batteries that run from 3.8V to 7.4V, drawing power from either an AC wall source (an AC cord is included) or a 12V DC power source. Additionally, the LCD battery charger features a USB power output to charge other devices with a USB power input, with powerful 2.1A output.
With interchangeable plates, the intelligent LCD charger can be used for world-wide brand battery models via the separate purchase of additional battery plates that are compatible with the intended battery model. The intelligent charger features an LCD display that graphically shows the charge status of the batteries. With overcharge, overheat, and short circuit protection, the duo charger safely, conveniently, and quickly recharges all professional Li-Ion batters and one USB-powered device.
With an implemented back-light in the large LCD screen, the readout function is enabled in the dark, giving you the possibility to use the charger at any place and at any time.
Large LCD Display Screen
A large LCD screen provides clear, accurate, and precise display of the charging status. The USB output and DC 12V input display charge mode provide a clear insight into the way in which the charging mode is used to charge your professional battery. With an implemented backlight, the readout function is enabled in the dark.
In Car Use
With a 12V DC power you can use the charger in a car, plane, bus or any location with a 12V-24V DC power supply.
Intelligent charging systems integrate the control systems within the charger and the electronics within the battery to allow precision control over the charging process. As a safety precaution with high-capacity batteries, a pre-charging stage is used. The charging cycle is initiated with a low current. If there is no corresponding rise in the battery voltage, it indicates that there is possibly a short circuit in the battery (zero volt activation). Constant current/constant voltage (CC/CV) charging mode is an effective way to charge lithium batteries. When a lithium battery is nearly empty, we take constant current to charge it. Charger CPU automatically adjusts charging current to be lower than the max charging current that the battery can accept. With constant charging, the voltage of the battery rises slowly until it reaches a maximum voltage at which point the charger switches the charging method to “constant voltage” and reduces the charging current. When the battery is fully charged, this state is stopped.
