What is the minimum voltage requirement?

I have the new beta firmware installed. Things seem to be better. BUT, I keep getting low battery voltage errors when I first start out on a ride. It doesn't tell me which pedal I put two new sets of batteries in the pedals last Friday. On the following Wednesday and Thursday, the low battery voltage errors came back. By Thursday, the pedals quit working within the first 5 minutes of the ride and never came back for the 4.5 hour duration. I checked the battery voltage with my DVM. 2.51 and 2.55 volts. That seems high enough. This was after about 10 hours of rides. Seems that the pedals should operate on something less than 2 volts. So I bought more spares and will try again for this week. A set of batteries per week is not going to be a good thing if that's what it turns out to be.
  • Try to measure the voltage of each battery individually with a 6.8K ohm load. See Chart 1(on last page) in the LR44 datasheet to estimate the remaining capacity under load - https://img1.emos.eu/files/product/attachment/1325007605_61-B7970.pdf

    Also, temperature has a big effect on battery capacity. Measure the battery under a 6.8K ohm load at the temperature you will use it at.
  • Question for T_Smit

    The LR44 battery datasheet specifies a 6.8K load for capacity testing. This is a very small load for a single LR44 which gives over 800 hours of life.

    For the Vector 3, what would the resistor value be to simulate the average current drawn from a single LR44. This information would be useful for users who have a voltmeter and can do a loaded voltage test on each LR44 battery individually. There are a lot of fake, or very old, LR44 batteries out there and this could be a useful test to see if the battery is OK under load.

    The user could also do the test at cold temperatures to simulate their riding conditions.
