This pro charger is designed for applications that demand adaptive charging for Lead Acid based and LiFePO4 (LFP) batteries. Battery with and without load can be connected to the charger all the time and the charger will keep on monitoring the battery.

Adaptive Charging Management
Lead Acid Battery
There are 5 Stage Charging for LEAD ACID based batteries namely:
Soft-Start/ Bulk/ Absorption/ Float/ Standby
When battery is deeply depleted (battery voltage is less than 24V) soft-start charging is activated with half rated charging current until battery voltage rises to 24.8V then normal bulk charge with full current will kick in. Both soft-start and bulk charges are in constant current without exerting high voltage to the battery. When the battery voltage rises to a preset value then constant voltage charge occurs with decreasing current which leads float charging with lower constant voltage to keep the battery ready and light refill for any self-discharge or light load.
The charger will enter into an energy conversation (Standby) stage with lower Float Voltage after long period of inactivity of 8 hours or more has been detected. This Standby stage also helps to reduce grid corrosion.
Charger will automatically give a refreshing cycle charge (fast bulk & absorption, float) at 7 days interval of inactivity. This is to keep the electrolyte and the cells of the lead acid battery in good working condition.
There is a manual equalization mode for lead acid batteries either in plate or cylindrical cells subject to the recommendation of manufacturer.

LiFePO4 (LFP)
There is a special charge algorithm and treatment for Lithium Ion Phosphate (LFP) batteries to ensure safe and optimal charging adaptive to the special chemistry of the battery which is quite different to Lead Acid battery. There are only two active charging stages namely Bulk and Absorption, at the end of Absorption is the inactive (no charging current) Standby Stage. There is no Float and no automatic refreshing cycle charge for LFP.

Battery with load
A load can be connected to the battery during charging as long as the load is not larger than the rated output of the charger.
The charger can be used to power up dc load when not connected to battery.

The charger is housed in a robust anodized Aluminum body completed with Poly carbonate end caps.

  • Battery temperature sensor is supplied as standard accessory
  • Front Exhaust design with temperature control variable speed fan for cool and quite operation.
  • 8 hour sleep Mode or the Half Power Mode with half power presents noiseless operation.
  • Half Power Mode for batteries with low Ah ( less than 100Ah)
  • Temperature compensated charging & Battery Protection

When connected to the supplied battery temperature sensor, the charging voltages changes with the battery temperature such that charging voltage decreases with rise of temperature and increases with drop of battery temperature.
When battery temperature is over 60ºC, the charger will shut down.

*Over Temperature Protection of charger:
At high operating temperature charger will gradually decreases the output power to protect the electronic components from further thermal stress and at the same time keeps a safe and continuous charging until the high limiting temperature 60ºC is reached, charger will then shut down and self restart when charger cools down.

  • Output short circuit protection.
  • Output reversed polarity protection with thermal fuse.
  • 7 LED with 4 dual mode plus 3 for indications of charging status and battery selection.
  • Single Set Button Setting with intuitive setting procedure
