Lii-PD2 Charger details:
1. Adopt DC12V1A (nominal) input;  two-slot independent charging and microcomputer management system;
2. The biggest highlight of this charger is that it can charge the battery regardless of polarity!
3. The charging current has three levels of 0.5A /1.0A/2.0A;  the default is 0.5A charging;  you can press the corresponding button to select the charging current;
4. During charging;  the LCD can display the channel CH and the charging current;  voltage;  time;  capacity and battery type of the channel Li-Fe 3.20V /
Li-ion 3.70V / Li-ion 3.85V (IMR); the charging current of the two tanks does not exceed 2A in total;  that is;  when one of the tanks is charged with 2A current;  and then the battery is charged in the other tank;  the front 2A current will drop Charge to 1A current; LCD will display FULL when the battery is full;
5. Li-ion (Li-Ion 3.70V) battery and nickel-metal hydride (Ni-MH) battery can be automatically identified;  and the lithium iron phosphate battery (3.20V) and
Li-Ion 3.85V battery;
6. With 0V voltage activation function;  1.65-2.20V can not be charged (but there will be activated current trickle type charging).
7. There are multiple safety protection functions such as overcharge;  overdischarge;  short circuit;  etc. At the same time;  it can intelligently and automatically identify bad batteries;
8. Charging mode: constant current and constant voltage.
