my charger only has one prong.. how do i test it without a short, or does it matter?

I thought your presentation was very good. Also, I didn’t have any problem understanding you. You gave me the information I was looking for.

thank you

My charger was showing green even when the battery was discharged, I wasn't sure if it was a battery or charger problem. This video enabled me to diagnose a charger problem and when I undid the connecting plug I found one wire hanging off! Quick solder and all is well again. Thank you for the video, could have been a long expensive process to determine the problem otherwise.

I have to same problem. What was the fix ?

Hi! Thanks for this video. Just a little question. Is the charger plugged to current while you test it? The battery needs to be on, right? What if I get sparks when using the tester? Hope you can give me advice.

Thank you for this, I ran some tests with my multimeter, as you showed, and it helped me diagnose the battery as faulty

OMG.. “Hi……ummmmm..”. That killed me Im dead lol😂😂

Randomly clicked this...was gonna just leave a troll comment & be on my way....but I gotta say putting the paper in between the pins is just such a simple brilliant move! I learned a new trick - look at me! Thanks, buddy!

When not using the charger should we leave it on or off?

Very Good, thank you

This video Demo on using a voltmeter for battery testing will be helpful for those without electrical testing experience. However, Not mentioned here is the battery mount plate that is attached to the bike! If good battery but no power to the motor that part could be the root cause. If testing just that adapter plate remove the battery and use the resistance (ohms) feature in your DMM (Digital Multi- Meter). Good luck!

Yes agreed check continuity on pins on plate

Also , if the charger feels warm after a few minutes , while connected to battery , it is working .

When checking the prongs (4 or 5 pin) you have to check more than just the + and - you have to check the prongs in between as well as they have wires (green, red, yellow) and they can be easily separated from the prong as these wires are really thin. They all should have same voltage except for the green ground wire which should carry very little voltage.

Hi so your example that this battery is ok right? I have a situation where it charges completely but shorter mileage? What's the problem there?

Lower mileage typical means your battery cells are wearing out assuming you are using throttle / PAS the same amount over similar terrain.

On some systems there is heating monitoring of the battery and the charger takes a signal back from an NTC thermistor. Sometimes this is hidden in sep cct within the frame of the bike. Measuring heat build up in Li ION batteries is critical.. no mafr wants to tell the User how he does it so it's harder to buy any other charger. TE Fidler NzL

Yeah if you look at that connection it's pretty much self-explanatory.

I've got the exact same charger as you and they only have 2 wires to the plug you insert into your device. Mine is giving me 42v but when I switch multimeter to AMPS its bouncing voltage all over I'm not sure if it's ment to do that can anyone help me please.

48v is nominal. The range for a 48v battery ranges between 54 and 42V

A battery like a car must charge above its nominal voltage ie acar battery is 12 volts but to charge the alternator puts in 14.2 to 14.6 volts where as a 48 volt ebattery would need 52 to 54 volts to charge the battery

Hi, When the battery is charging, the LED indicators will flash showing the charge level. One green ball represents the low charge. Two green balls represent half charge. Three green balls represent a full charge.

The battery or charger is dead. Or you have wired the test leads incorrectly or the meter you’re using is broken. I would test the meter by connecting it to your local AC mains supply as an example to confirm that it reads a voltage. Or get a battery like AA battery and measure across both ends of the battery for DC voltage and verify the same.
