Note:
1. When you connect the balance charger to power, if the power indicator does not light up, it shows the charger is not well connected to power.
2. If the charging indicator does not light up after you connect the battery to charger, please check the connection, and whether the battery’s voltage is too
low (<1.5V/CELL). If a cell is lower than 3V, the charger will provide low current recovery charging for 3 minutes; if it fails, the charging indicator will
blink 0.5 seconds, indicating the battery is damaged. Only when each of all the cells reaches 3V, it will turn to normal charging. The charging Indicator will
light up green when the battery is fully charged. Please take out the battery in time to avoid battery deformation or even explosion caused by overcharging.
3. The battery may fail to be charged because of over discharging, thus remember to mount a battery indicator alarm. When an alarm beeping is heard,
please take out the battery to charge in time! You can try to recover the damaged battery if you have a stabilizator. Here's how to do:
1). Adjust the output voltage to 12.6V as shown in Figure 1-5;
