Looking for a Silent Charger for My E-Bike Battery (Help Needed!)

[Kilo_me]

Hi everyone, new here,
I recently purchased a new e-bike battery and charger. this from Amazon for my BBSHD.
I understand that it's always best to use the charger provided by the manufacturer.
However, I also need to charge the battery at my office space, and unfortunately, the included charger fan is just too loud for that environment.

Does anyone have any recommendations for a quieter (ideally silent) charger that would be compatible with my setup? Preferably form amazon?

Thanks in advance for your help!

There are many. I have one in my parts box. Are you going to solder on a compatible connector yourself, or would you rather post a pic of the connector on your existing charger so folks can suggest a plug n play unit?

If you can only charge at about 3A, then use Meanwell HLG-185H-54A.

This is the plug currently used in the stock charger provided by the manufacturer.

Yeah, don't put more than 4A through that plug.

I can't determine the diameter of the plug just by the photo, but you just need to search on a "52V 3A charger" on Amazon or Google, and pick one of the brick style with no fan rather than the aluminum case style with a fan, and the right connector. Here's an example with a 5.5mm barrel connector:

As above, be really careful about the diameter of the plug since there are two or three that look the same, but are not interchangeable.

A detail for you to consider.

If you charge a Li battery to 100% every time, it will last some period of time in use.
If you charge it to ~80-85% each time, it will last about 3 times as long. Often longer.

One fellow I worked with charged with the manufacturer's charger to 100% every day, and he had to replace his battery by the end of a year. Li batteries at 100% are also more likely to catch fire, and especially if left on charge over night. Not guaranteed every time - but definitely more likely, particularly cheap ones.

As you are thinking of what to buy, think about the cost of replacing the battery. Total up the cost of 3 batteries, and then compare that to the cost of buying a charger that is smart enough to stop at ~80%.

The battery for my trike (with the size/range I have chosen) costs as much as the Grin Satiator, which means in turn that I am saving the cost of an entire battery by not using the stock (dumb) charger. After this original battery goes, I get the savings for free, as the Satiator will continue working - it's already paid for. It will also probably work with any battery I buy (that isn't proprietary) as it's very programmable, and can handle many different battery chemistries.

You can accomplish the same savings by watching the charge level (voltage) and stopping the charging when you reach the level you decide to use. There are also other chargers that are not dumb.

I also have a solar charger that I can program to it's end voltage, which accomplishes the same.

The Satiator is water-proofed (I don't know if it can stand immersion, but it's guaranteed to handle weather)..

Batteries are very expensive, and cheap ones catch fire. Good batteries and chargers are well worth the price. I don't buy expensive, and I don't buy cheap - I buy good, so I'm not wasting my future.
