• Can't reach the maximum charging current?
• To protect battery, the system automaticaly identifes battery voltage and selects the most appropriate curent to charge, for example, when 12V battery voltage less than 11V, it automatically charges the battery at the maximum current.
• The LifePO4 battery is not fully charged?
• When the battery is fully charged, it has a callback function, reducing the charge by about 1V-2V, which is normal. Added a small current after full charge uninterrupted charging.
• The charger cannot recognize the battery? It's not working?
• Over-discharging battery can cause the charger to fail to recognize the battery correctly, so it is recommended that users measure the battery voltage before use.If the charger is not working, try using the powerful mode.
• How do I activate the charger's high-power mode?
• Press and hold the button for 6 seconds until the buzzer sounds, then connect the battery. Press and hold the button again for 6 seconds. Note: Please disconnect the power after running in high-power mode for 5 minutes to avoid damaging the battery.
• 1 Only charge the lithium battery with battery protection board(BMS).
• 2 Charge the battery below 15AH with the minimum current
• 3 If the lithium (BMS) cannot reach the cut-off voltage, it needs to be charged in low current mode because the BMS triggers the protection of the battery.
• 4 It is not a jump starter or battery booster
• 12V 24V Car Battery Charger
