20 Amp Battery Charger

• Q 1 : Why can't I reach the maximum charging current?
• A 1 : In order to protect the battery, the system will automatically recognize the battery voltage and choose the most suitable current to charge the battery. When the battery voltage is low (e.g. for example, the 12V battery voltage is less than 11V), the system will automatically charge the battery with maximum current. (3-speed adjustable charging current, high current, fast charging).
• Q 2 : Is the LifePO4 battery not fully charged?
• A 2 : When the battery is fully charged, it has a retracement function that reduces the charge by about 1V-2V, which is normal. Add small current to charge uninterruptedly after fully charged.
• Q 3 : Is the fan noisy?
• A 3 : It is normal for the fan to generate wind.
