Different charger from Sondors for 48V 14Ah?

Recommended Posts

I have two new folds delivered August 2018 from the netherlands. The two charger for the batteries (48V 14 Ah) are exactly the same, but the charging is different. One charger just switches from red to green light when connecting the battery for charging. The other charger shows some minutes the green light, somtimes it is flashing green and soemtimes after some minutes it is changeing to red light. The first charger has a very noisy fan, the second is nearly calm. I think, the second charger is slower than the first one by charging. Do anyone have the same experience.

Hello Markus,  the noisy fan is annoying but otherwise non problematic, just charge in a cool area (inside AC) to insure adequate heat disapation. 

Make sure the data plates on your chargers match. 

If you are following prescribed charging instructions, you certainly have some issues. The flashing green would most probably indicate an intermittent connection to the wall outlet power supply..

The time to full charge can only be determined by knowing the starting voltage of the batteries you’re comparing. The lower the starting voltage the longer the charge cycle. 

I would suggest that the BEST way to insure your batteries are charging to capacity, is with a quality aftermarket charger.

and this bullet/barrel connector dongle.

This Advanced Charger will let you select, not only the charge  rate amperage (1 to 5amps)but also the percent of full charge (80/90/100%), both options to help insure the longest life cycles of your  battery packs.

Hey @Reddy Kilowatt - This is great, I didn't know about this charger. Do you know if it is quieter when charging at 1 amp for instance than the noisy charger that comes with the 48V 14Ah battery?

@Chad Lauterbach,   All charger fans are noisy and both my Sondors 36v 12.8amp charger and my Luna 52v Advanced Charger fans have gotten louder with age.  My 52v 4amp fixed rate, Electro Bike World Charger, is not as loud but it’s newer. I might try and oil the fan bearings on the older chargers with a pin point oiler when I open them both up to readjust the max voltage and cut off, the values drift with age slightly. If the noise is problematic, in your environs, it’s a simple task to create some baffling with foam insulation board to absorb and deflect the noise or remove the batteries for charging.  It doesn’t bother me as I charge my bikes in my detached studio.  Charging amperage nor percent of charge have any impact on noise, but charging at lower amp rates and to 80 or 90% can contribute to longer pack life. Typically it’s the speed of the fan blade tips as they approach the speed of sound that creates the most noise from the fans.

I did end up picking up the Luna Charger 48v Advanced:

To replace my Elctro Bike World one:

48v-lithium-battery-chargerhttps://a3ee3610-0553-11e5-8794-f04da2069d31.onlinestore.godaddy.com/products/48v-lithium-battery-charger

I will say not only is it awesome having different charge rates and max fills, but it's fan is a LOT quieter. It's not silent, but it's made me a lot happier person when I'm charging my bike. :)

One important note with the LT48 is the Luna Charger has a XT 60 connector and the LT48 uses the Anderson Power Pole. You'll need an adapter like this: https://www.servocity.com/anderson-powerpole-to-female-xt60-connector

Took me a while to find the right part on that one.
