• Can a 12V Lead-Acid Charger Charge a 4S LiFePO4 Battery? Same 14.6V Voltage Is Still Not Enough

  Can a 12V Lead Acid Charger Charge a 4S LiFePO4 Battery? Why 14.6V Does Not Mean Compatibility A common customer question is: “I have a 12V lead acid battery charger with a 14.6V or 14.7V output. Can I use it to charge a 4S LiFePO4 battery?” The answer is: A standard 12V lead acid charger should not be used directly with a 4S LiFePO4 battery unless the charger manufacturer specifically states that it supports LiFePO4 charging. Although a typical 4S LiFePO4 battery has a full charge voltage of about 14.6V, and some 12V lead acid chargers may also have a charging voltage of 14.6V or 14.7V, similar voltage does not mean charging compatibility. The charger must also match the battery chemistry, charging algorithm, constant voltage stage, and charge termination method.

• Solutions and Maintenance Guide for Over-Discharged E-Bike Batteries

  Many people have developed a bad habit of leaving their electric bike batteries on the bike when they are away, without turning off the air switch, and not riding for several months. When they come back to ride after several months, they find the bike has no power, and the battery cannot be charged. Even if they plug in the charger for 24 hours, the indicator light remains green. This is because the battery voltage is too low, and if the voltage difference between the battery and the charger output is too large, the charger cannot deliver the charge to the battery.
