Atem Power 12V DC to DC Dual Battery Charger RV Caravan 20A 40A Battery Maintainer

DESCRIPTION
If you’re planning an off-grid camping a DC-DC charger by ATEM POWER will be your perfect companion for a dual battery setup when you cannot access main power. This device which is designed to do a full charge cycle with the ability to choose either Lead Acid AGM Gel calcium LiFePO4 batteries and apply the suitable charging profile to prolong their lifespan also incorporates Re-selection Ready mechanism that allows you to re-select the battery during charging by long pressing “POWER”. And it can be connected indefinitely when you’re all set up! This ATEM POWER DC-DC charger is also a fully multi input charger that is able to charge from either an alternator to get the best possible rate of flow into your secondary battery and keep it up on the drive or via solar power with the built-in MPPT controller for faster charging and reducing load on your engine! And a multiple of protections are integrated to keep battery safe especially in case of accidental terminal misconnection.

FEATURES
Dual Input: This Charger is designed to effectively pull power from solar panel or vehicle’s alternator to charge your auxiliary battery.
Multi-Stage Charging: This charger integrates standby pre-charge constant current charging constant voltage charging full charge and re-charge.
Multi Battery Selection: This DC to DC charger by ATEM POWER is compatible with Lead Acid AGM Gel calcium LiFePO4 batteries.
Built-In MPPT Regulator: The regulator is designed to harvest up more energy from the solar panel.
Multiple Protection: It integrates over-charge short circuit over-temperature thermal load solar input overload input/output reverse polarity protection.
Internal Temperature Monitoring: This mechanism can effectively protect the circuit board thus prolong the lifespan of the charger.
Sturdy Construction: Sturdy aluminum housing is built to resist harsh conditions and quality wires are built for long last durability.
Upgraded Charging Algorithm: This algorithm is designed to select the optimum charge mode and revive your discharged battery.
Smart Alternator Compatible: The ACC wire can be wired to the ignition to adjust voltage cut off which is suitable for modern vehicle trailers and caravans.
User Friendly Design: The LED indicator shows real-time stage of charging and memory function is integrated to make your charging more convenient.
