I an trying to benchmark a recently-purchased "52V
14Ah/728Wh (Samsung 35E/14S4P)" battery.
But my numbers are not even beginning to add up.
To Wit:
Aside from the substantial descrepancy between case #3 and cases 1 & 2 in watt hours used, there is the large descrepancy between all three cases and the claimed 748 Wh.
Can anybody elucidate?
Am I on a fool's errand?
All I really care about is that the battery has more miles in it than I do on a given day... and that seems tb the case so far - but the 200-ish vs 748 thing has me wondering if I bought a bad battery.

To Wit:
- Discharging from 56.8V (a little over 85% charged) down to 45.4V (20% charged) got me 24.2 miles, and supposedly used 235 Wh.
- Discharging from 56.7V down to 48.2V got me 30.1 miles, and supposedly used 242 Wh.
- Discharging from 58.5V (pretty close to 100% charged) down to 43.0V (pretty close to zero) got me 33.3 miles, but supposedly only used 170.9 Wh.
