I have an electric scooter with 48V25Ah lithium-ion battery.
It takes 6 hours to charge the battery with the charger (its called C300) that came with the scooter.
The charger says:
input: 200-240VAC 3.0A
output: 54.6V 5A
I have measured the usage with a cheap meter on the 240VAC side and it says it is using 2A and about 288W when the battery is charging at the highest.
54.6 x 5 = 273 watt right? So i guess the charger is running as full capacity.
But i dont understand if the meter says 234 voltac 2 amp 288 watt at the same time.
Because 234 x 2 is not 288.
Does that calculation with voltage x amp = watt not work for AC ?
I would like to know what decides how fast the battery can charge.
The charger is called C300 (48V5A).
There is another charger called C1200 (48V20A).
So will the battery charge 4 times as fast with C1200?
Or how can i know what charger to get?
Can i damage something if i connect the C1200 or other charger with higher A to the battery?
The battery have two connectors.
Can perhaps one charge the battery faster then the other?
Here are some links with pictures.
