Anyone know of a fairly inexpensive 15s li-ion battery charge that can have output voltage adjusted down to 60v or so?

I am looking to undercharge a 15s 63v max li-ion battery. I would like a charger that can be adjusted (internally or externally) below 63v. I am guessing I would prefer output voltage adjust-ability between 63- 60v or so and amperage does not matter much to me. I have read that some people have been able to adjust the output voltage on their power supplies internally with adjustment screws, but those models were all for charging 36v and 48v batteries.

I did see this inexpensive charger on aliexpress, however I cannot tell from the image (and they use the same image for other models) if there are adjustment screws to reduce the output voltage inside the charger.

Does anyone have any experience with anything like this or perhaps know of a different model? Thank you.

A 14s Charger (58.8V) will go up to 63Vmax adjusted.

Pretty much the same as you posted but 4A for the same price.

Wonderful! I would be able to charge my 14s battery with that too then, if needed. I assume you have to open it up and turn adjustment screws to adjust it? Perhaps this one would be ok? I do not need 4a, my battery is only 5ah.

Yes, you are gonna have turn the voltage knob located by the output wires, it also has current adjustment, located by the shunt.

Awesome, I will order either the 3 or 4 amp one today. Thank you very much!

I love my Ping kingpan 5a. I adjusted to 72v for 6 weeks it popped a capacitor rating for 63 volts I found another one rated for a hundred volts I put it in and adjusted that 48 volt to 84 Volts for my new battery I don't know how many amps cuz I haven't got to meet her (meter ) yet so I don't run it but that's pretty amazing. How do these charges work if there's some kind of push pull ?

Also, here's a handful of more options. If you have a 15s 5ah battery, you might want to consider the 14s 2a charger:

I have two of their (SZXJR) 24s 9a chargers, and been using them for the last week. They've delivered as advertised so far.
