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...

I've got three 48 V batteries, and they all have a "capacity" test button that show 4 out of 4 lights at any voltage above 48V, so the scale is kinda useless.
I have the same display, and I set it to read voltage.
It works great, and you can see the voltage sag and rebound in real time as you pull power from the battery.
Battery voltage and capacity aren't exactly linear, and the last few volts get used up A Lot faster than the first few volts, but you get a feel for it over time.
When I get down to 48V, it's still above the half way point of my voltage range (40v-54.6v), but I've used up about ⅔'s of my capacity.

I'm not familiar with that bike... but if you can get an accurate voltage reading on the display that's the best way to monitor. It becomes second nature after a few rides to interpret.
