DC-DC Charger for Lithium Battery

Charging a lithium battery from a DC source is a different job from charging it from mains power, and a different job from simply holding a voltage. A lithium charger must follow the battery's charging profile: a controlled current phase, then a controlled voltage phase, with the transition and the termination handled correctly. Getting that profile wrong shortens battery life at best and damages the battery at worst, which is why the charger must be matched to the chemistry, not just to the voltage.

The charger category on this site lists chargers for 12 volt, 16 volt, 24 volt, 36 volt and 48 volt lithium batteries, and the fully specified bidirectional series serves 12, 24, 36 and 48 volt lithium and AGM batteries, with waterproof construction, bidirectional energy flow, RS485 communication, and support for charging while the engine runs. That series is the detail-page answer for lithium charging on this site, and its page states the full published specification.

For lithium charging at a voltage or in a configuration not covered by the bidirectional series, the correct route is the inquiry: state the battery voltage, the chemistry, the capacity, and the source, and confirm the charger, the quantity, the price and the delivery time before ordering. Certificates are available upon request.
