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.
