High Quality and High Performance Constant Voltage Constant Current ALQO SMPS charger is very simple to use for 24V (6S) Lithium Ion battery packs. It is very easy to use, simply plug it into the mains power and LEDs will light green and then flash to orange to indicate the charger is ready. Connect your battery to the DC leads/clips of the charger, the battery starts charging. When the charger starts charging the LEDs will glow constant red, when LED turn green the battery is fully charged, disconnect the battery before switching off the charger. It is very useful for ebikes.
