How to switch from 48 volts to 24 volts
< br >
The most convenient way is to use two identical 24V batteries in series and then the charger is ready. If you must 48V to 24V charger, this line is more complex to use switching power technology.

1, \"the battery is 48V\" may be four 12v batteries in series. If so, you can open the battery box and connect the two pieces in series.

2, \"the battery is 48V\" if you do not want to move the battery box, you can use two 24v bulbs connected in series.

3, with two identical resistors in series, the middle is 24, but a lamp is different, the lamp resistance of 3 ohms.
There are two methods of reference.
Give the battery a partial voltage resistor in series, so that the resistance partial voltage value reaches 24v, use a multimeter to measure the total resistance of the 48V charger, such as 50Ω, then series a 50Ω resistance can be.
Method two, the two 24v batteries are connected in series and charged with a 48V charger.
