The Powermax PM3-55LK AC to DC Converter/Charger is a fantastic converter/charger that works tremendously well with Battle Born 100Ah 12V LiFePO4 batteries! The most prominent feature of this charger is the ability to manually adjust the charging voltage. This is huge for LiFePO4 batteries because it enables the user to charge their LiFePO4 batteries to the ideal 14.4 V and get the most life and power out of their battery!

Once the charger is adjusted to the 14.4 V, the unit will have the following values for its 3-stage smart charging:

Bulk Charge: 14.4 V

Absorption Charge: 13.6 V

Float Charge: 13.2 V

Follow the steps below to adjust your Powermax PM3-55LK to work with Battle Born Batteries.

 

Tools required:

Phillips Screwdriver
Multimeter

 

Step 1:
Disconnect unit from power and move switch A to the “Adjusted Fixed Voltage”.

Powermax

Step 2:
Plug charger into AC source. Connect multimeter to positive and negative outputs of charger to measure the voltage.

 

Step 3:
Use a Philips head screwdriver to gently adjust Switch B until you have a voltage value of 14.4V on your multimeter.

 

Step 4:
Once you have achieved a voltage of 14.4V, unplug the unit and move switch A back to “3 Stage Charging”.

 

Step 5:
Reconnect battery to Powermax and with your multimeter and plug it back into power. Then measure the voltage at the battery and at the output terminals; these values should be about the same. If the voltage at the battery is significantly lower than 14.4V, go back to step 3 until the voltage at the battery is 14.4V.
