  1. I wonder if the insulators in the atty would melt doing this? I have 24 kanthal which i could try around 1 ohm and 40w discharge, but that would only be 3 wraps on 1/2inch lol. I wonder if the ohm we test at has anything to do with accuracy of discharge? The one john linked is 1 ohm 100w.

  2. I will try to get some kanthal but if the resistor is cheaper where do i buy it? I seem to have fixed the problem for now by letting it sit over 100% on the charger for a hour after changing the Wh calculator a few times. I am not sure if it will stay that way but I am also interested in seeing the curve for this type of battery as might help others that are thinking of Lifepo4 batteries.

  3. 1050mah 3s 9.9v lifepo4, set at 10.4 Wh via calculator, it was set to the default 8Wh before and was working but recently this battery jump has been happening so i used the Wh calculator. Since i got it, about 3 weeks ago it was fine till 2 days ago. KTMrider all cells are evenly balanced in the device monitor. batteryprob.png 

  4. My chip started to act strangely by jumping from 92% to 65% and has been doing this behavior for the last few days. I just uploaded new firmware and software, and plugged in data for wh according to my battery spec. The balance is fine on batteries. Room temp and board temp seem way off too. Mabey I should try a hard reboot?

  5. After 1 1/2 hours, cell 1 -3.5, cell 2 -3.5 cell 3 -3.36. Strange that cell 3 never goes above 3.36. I think my solder is good on balance charger, not sure what could be going on other than cell 3 is bad? I did accidentally let it charge without changing it to lifepo4 in escribe for a short time.
