Battery discharge rate

2.37K viewsHardware


Does anybody know what the voltage you see left on your tentacle when you plug in the app means in relation to battery hours left?

e.g. if it reads 3.5v, what roughly does this mean? 20 hours left? 10?

Usually these batteries stay fairly high and then quickly drop off near the end of their cycle, so I am wondering how to interpret the volts as useable time left on the unit.


Thanks, Peter. I kind of thought the makers of these units would have an idea, or even a graph plotting voltage reading against time left. What i don’t know is if it stays high, then abruptly plunges, like many lithium cells, or declines gently at an even rate. Which makes the reading the voltage very difficult to know if you have got a full day left or what.
