Remark: Calibration take some time and patience. Pushing A and B button at the same time is a kind of Russian roulette. Setting cycle time and LiPo/LiFe can be problematic. If for instance cycle time is set on 4 seconds pushing A and B to confirm (and you mistakably push A and B not exactly on the same time) the time is set to 3 or 5 seconds. Unfortunately you have to start all over at the beginning. Produce a graphic of the LiPo total voltage during the flight together with the hold the lowest voltage per cell is not possible. Its the graphic or the hold function.After calibration with a 6 S power source the In- Flight data logger works perfect. Just press button A just before flight and afterwards you know exactly the lowest voltage per cell during the flight. I set the sample rate or cycle time on 4 seconds which gives me 8 minutes measuring time. Dont forget to set the battery type on L (LiPo) Remark: during calibration be sure you A and B at the same time otherwise the setting changes un-intentionally.display is not clear plusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusThis device is really useful for measuring the pre-flight voltage, minimum voltage in-flight, and voltage after the flight. The difference between the minimum in-flight and after flight voltages gives an indication of battery health. In my setup the difference is ~ 0.2 volt, and I can expect this to increase as the batteries age. I can use these results to adjust my flight time (transmitter timer) so that the battery voltage does not discharge too low in-flight.
Disapointing - dosent show the correct voltage. First I thought my charger ballances wrong. Tried another charger. Both chargers show 4.20V on all 6 cells but the logger shows 4.20, 4.20, 4.17, 4.18, 4.19, 4.21
to bad for $20must have tool. Wery good for indication of the health of the battery. For JST, XHT connectorsA nice little tool for managing batteries, but unfortunately can not PolyQuest connectors.
Otherwise, everything very well.
preciso, leggero, prezzo buono.
5 stellet of a bad connection in it, as I sometimes have to press on the outer cover right where it says "in flight voltage logger" to get it to work. Probably a bad solder job... If it wasn't for that, it would definitely be a five star review. Reply to this..I think it will help to improve battery life too.
