100 mW
I've read several posts that the wattage display on the Bafang controllers is not very accurate. I have the Bafang C963 display and was curious if it was accurate. I have an Eagle Tree eLogger I was not using from my RC airplane and I think I'll mount it to my bike to track battery data. I did a short run and the wattage numbers from the eLogger matched that of my C963. What I like about the eLogger is that it can be configured to display the data you like, and if you set it to take 1 reading per second, it will record about 6 hours of data you can download to your PC to chart, replay, review, etc. On mine I set it up to display wattage, amps, voltage, and cumulative mAh. Anyone else use one of these? I was disappointed that the C963 display does not display a numerical voltage # or cumulative mAh to know how much juice the battery has put out. With this tiny display it gives me data to manage my battery care.
** EDIT ** This doesn't seem practical due to cost, but since I already had 2 of the V3 loggers in my RC hobby box, it was a cheap alternative for me given no cost involved to add it to my bike. The new v4 eLoggers are $70 at Amazon and the LCD Display about $30. So about $100 total. The new V4 handles 100 amps and voltage from 5V to 80V. Current is measured with a true Hall Effects sensor, and not a resistance shunt, which produces heat and sucks power from your system.
