VMAX (VBC1215LFP) 15A 12V 3-STAGE SMART LIFEPO4 BATTERY CHARGER / MAINTAINER

The 1215LFP is a fully Automatic, 15A, Smart 3-STAGE LiFePO4 Battery Charger/Maintainer.
Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely.
The 3 stages are:
Bulk; Absorption & Float.

Input Voltage: 110-240VAC
MAX Input Current: With Load: 3.0A, No Load: 0.05A
Input Power: With Load: 219W, No Load: 1W
Nominal Voltage:12V
Bulk Charge Voltage: 14.4V-14.8V, Current: 15A
Absorption Charge Voltage: 14.6V. Current: 15A - 1.5A
Float Voltage: 14.6V with Pulse Charging.
Bulk Charge Current: 15A
Battery Type: LiFePO4
Recommended Battery Capacity: 15-225Ah
Operating Temperature: -20F ~ 115F (Note: LiFePO4 batteries with BMS will not charge below 32F)
Storage Temperature: -40F ~ 165F
Connector: Insulated Alligator Clamps
Charging Cord Length: 4ft
Size: 8.3" L x 4.3" W x 1.9" H
Weight: 3.3 lb.

CHARGING INSTRUCTIONS:

1. Connect the RED Charger alligator clamp to the RED Positive (+) Battery Terminal.
2. Connect the BLACK Charger alligator clamp to the BLACK Negative (-) Battery Terminal.
3. Connect the Charger AC power cord to the 110V/220V AC mains powered socket.
4. Upon detecting a good battery with minimum Voltage of 8V, LED will TURN RED as Bulk Charging begins.

If Battery is almost charged when connected, and charging current is <1.5A, LED will Blink RED then switch to GREEN as charger goes into Float mode.
If Battery voltage is below 8V, LED will turn GREEN while charger performs soft start charging; to raise the Battery voltage to 8V.
If the Battery accepts the charge, LED will turn RED at 8V and BULK Charging begins.

5. As the charging current drops below 1.5A, LED will switch to GREEN and Charger will go into Float mode.

Charger will slowly bring the battery to 100% State of Charge as charging current drops to 0A.
If LED does not turn RED at any point after powering Charger and connecting it to Battery, disconnect and troubleshoot Battery and Charger.
Most probable cause is a defective Battery.
