Wagan 25A DC to DC Battery Charger

25A DC to DC Battery Charger

Purposefully designed to accurately and safely charge auxiliary batteries, the Wagan Tech Dual-Input DC to DC Charger series ensures your batteries are kept at optimum performance levels that will enhance performance and extend their lifespan. Our charger can be used with standard and Smart Alternator systems and is perfect for use with solar systems and those choosing not to utilize solar charging.

Intelligent 3-Stage Charging

Our Intelligent 3-stage charging uses a high speed microcontroller and a proprietary charging algorithm to deliver a sophisticated 3 stage charging process.

The first stage, bulk charge (constant current), charges the battery fast while the second stage, absorption (constant voltage), ensures the battery is thoroughly charged.

The third stage, float, monitors and keeps the battery at a safe voltage allowing it to be maintained and ready for use.

Works with Most Battery Types

Our DC to DC Charger works with:

SLA (Sealed Lead Acid)
Flooded Lead-acid
Gel
AGM (Absorbed Glass Mat)
Calcium
LiFePO4 Lithium Iron Phosphate batteries*
*LiFePo4 batteries must have a Battery Management System (BMS) in place.

Solar Panel Charging (MPPT)

Our DC to DC Charger utilizes sophisticated MPPT (Maximum Power Point Tracking) solar regulator technology. MPPT maximizes the power generated from your solar panels to the auxiliary battery. The static efficiency of the MPPT algorithm is >97%, and the dynamic efficiency is >95%. This DC to DC Battery Charger can be used with solar panels up to 375W combined in 12V systems and 750W combined in 24V systems.

Mounting plate is integrated into unit's design making installation a breeze
 

Integrated Safety Features

  Spark-Free Protection
The DC25A will not start charging the battery (no output) unless the load is securely connected (except the LiFePO4 mode which allows 0 volt start); this prevents the leads from sparking due to accidental short circuit making the charger safer to use around batteries.

  Reverse Connection Protection
Reverse Connection or "reverse polarity" on input and output terminals will not damage the internal circuitry.  Our Charger detects reverse connection conditions and indicates to the user whether input or output connection is reversed.

  Over and Under Voltage Protection
The charger will automatically shut down if there is an over voltage or under voltage condition detected to protect the user and the charger.

  Over Temperature Protection
The charger will lower its output current if the temperature of the unit begins to exceed its pre-set threshold.

Completes your Power Eco-system

For systems with Solar Panels, Power Inverters, and auxiliary batteries, the DC to DC Charger completes the power eco-system by providing a way to connect, power, and recharge everything.
