Such as 48V charger, high voltage is not greater than 59.6V, greater than this voltage, charging may not turn the lamp, low voltage is not less than 55V, lower than this voltage caused by insufficient charging, long time easy to battery loss, current, such as 48V20A charger, great current is not greater than 3A. More than 3A May result in early battery water loss, very low not less than 2.1A. Low voltage of this current causes undercharging.
1:48V new battery requires charger parameters, high voltage 58.5-59.7, not less than 58V, lower than 58V will cause insufficient charging, higher than 59.7V May cause charging do not turn the lamp. The current of the turn lamp is about 0.4-0.7A, and the actual voltage is about 55.5V, which is lower than 50V, resulting in insufficient charging and loss of battery power for A long time
2:4820 Battery requires a large charging current 2.4----3.3A, lower than 2.2A slow charging, poor charging effect,
3: The actual power of the charger less than 30 yuan on the market is small, the parameter design is not accurate, please pay attention to distinguish
4: charger voltage regulator circuit failure will cause the output voltage 75- 130V, charging battery hot do not turn the lamp.
5: When the new battery appears and the range of the 20A battery is less than 30km and the 12A battery is less than 25km, please check the parameters of the charger. If it is not clear, please replace the high-quality charger and use it again to solve the problem
6: The new battery does not turn the light, please replace another high quality charger test machine,
7: Under normal conditions. 4820 new battery charging time is about 10 hours, the mileage of 40-60 km, 4812 new battery charging time is about 10 hours, the mileage reaches 25- 40 km, if the normal charging time exceeds more than, please replace the high quality charger to use again, feedback information
8: There are a lot of charger internal circuit, input and output wiring aging, resulting in, sometimes can charge, sometimes can not rush. The battery is seriously affected, or the circuit fails in the charging process, causing the charge pack. If this happens, please directly replace the high-quality electrical appliance and use it again.
