Smart DC to DC battery charger 12V to 24V or 24V to 12V and MPPT solar Dual Input Mobile APP Connection on board battery charger

B2B Charge

It means to charge the main battery through alternator and starter battery. If it is not used in the vehicle, you can also use one battery to charge another battery

1. When the vehicle is running, the vehicle alternator can quickly charge the main battery through the charger at full power

2. The charger can charge the main battery according to the specified voltage and current by boosting or stepping down to ensure that the main battery is in accordance with the standard.

MPPT solar charger

1. The charger can increase the charging efficiency of the solar panel by 10-30% through MPPT technology (search for the maximum power point)

2.  The charger can charge the main battery according to the specified current by boosting or stepping down to ensure that the main battery is charged according to the standard charge curve charging

3.  When the vehicle is not used for a long time, you can maintain a small trickle charge flow for the starter battery to ensure that the starter battery has enough electricity to start the vehicle

Other Functions

1.  Fully automatic charging: In order to continuously charge the battery, the controller can always be connected to the car battery.  When the charging energy is stopped, such as the car stops driving, the battery will not discharge in the reverse direction.

2.  Multiple protection functions: with overheating, overvoltage, short circuit, wrong connection protection

3. External temperature sensor: The ambient temperature will affect the parameters for charging the battery.  The controller needs to perform parameter compensation according to the temperature of the battery, especially in places with large temperature changes.  It is strongly recommended to install a temperature sensor.

Note: Lithium batteries do not require temperature compensation

4.  Lithium battery automatic wake-up function: When the lithium battery BMS is protected for some reason, the controller can automatically wake up the BMS and continue to charge the lithium battery

Battery life and efficiency

1 Ensure that the battery installation environment is ventilated and dissipated.  The LiFePO4 battery is recommended to work in an environment above 0 degrees Celsius, otherwise the battery characteristics will drop a lot

2.  The battery must be fully charged and stored, and it must be charged regularly to ensure that it is not stored under power, otherwise it will affect the battery life

3.  Lead-acid batteries that are completely empty must be charged as soon as possible, otherwise it may cause permanent damage!

4.  The lithium battery must have a BMS (Battery Management System).  Try to avoid completely emptying the battery.
