Lithium Ion, Lithium Polymer Battery Charger, DC-DC input, 3 Amps

Switch mode lithium ion chargers are designed to effectively charge lithium ion batteries while protecting the batteries from overcharging. All charger ratings are based on a nominal input of 10-30VDC. The output current ranges from 1.0 Amps to 3.0 Amps

Features:

• 3 step charge control with current detection as charge termination
• Switch mode charger with universal input voltage
• Protected against reverse polarity and short circuit
• Charges 3-8 cell battery packs
• Waterproof (IP67) version available
• LED status indicator
• Custom specifications on request

Functionality:

Once the charger is attached to a lithium ion battery and then plugged in, the charging process will begin. The charger will subject the lithium ion battery to three steps of charging.

During the first step, the charger enters into ‘fast charge’ mode. During this step, the charger is in constant current mode with the current rate remaining at its maximum rating.

In step two, the charger is in constant voltage mode (current is no longer being delivered at its maximum rate). The battery is nominally 80-95% charged when the LED indicator changes to orange. The charger stays in this mode until the charge current decreases to the charge termination level.

In the third step, the charge process has stopped. Charging has ceased as no current flows to the battery.

Note: The Prices include CORDSETS and adapters. Please call / specify the country this will be used in for us to send an appropriate cord. If no country is specified, we assume that it is for North America.

(Please mention the voltage and Amp Hour ( Ah) rating and or the watt hour (Wh) rating of the battery pack the charger will be used for while you place your order)
