Recommended low voltage discharge of a 60v Li-Ion battery

[wntrhwk]

Hello, I am hoping to get the most life out of my battery and have heard that I can do a charge/discharge profile at around 80/20%, that is discharging no lower than 51.8v and charging to around 63.4v. Does this sound reasonable for a normal charge/discharge cycle? Thx for the help.

If you don't use all of that in a single ride you can even tighten that number ( eg 70/30%) if you don't mind charging between every ride.

Gionnirocket, thx for the reply. I can do 70/30, I am getting pretty decent mileage. Just wanted to make sure I wasn't damaging anything. I am not trusting the display, which shows completely depleted at a manually measured 58v. The battery itself has a "capacity" test button and it shows 2 out of 5 lights. I assume this is going to be more accurate and would be the stats that the battery BMS would be using.

What bike / motor /battery do you have?
I have a Bafang M620 w/860C display
My display % is off as well... But the display can be set to show voltage which is very accurate.

Here's some info...
