(6 of them) As far as resistance goes, the lowest in ohms is .035ohm and the highest is .044 ohm. The average for all of the 6 is about .037ohm. I was wondering, since I haven't used these batteries all that much, is this good for being in the early stages of its life? My voltage sag right now at 40a with two in parallel is around 3/4 volt which seems very high for the amperage. This test was done under a 20a load at room temperature. Battery: Turnigy 3000mah 4s 20-30c ----------Rest voltage--------voltage under load-----resistance (ohm) Batt1-----16.57---------------------15.81--------------------.038 Batt2-----16.59---------------------15.87------------------- .036 Batt3-----16.58---------------------15.89--------------------.0345 Batt4-----14.96---------------------14.09--------------------.0435 Batt5-----15.79---------------------15.08--------------------.0355 Batt6-----15.65---------------------14.65--------------------.05 Another thing. When flying fpv, I have two of these in parallel so its 6000mah. I usually fly until my voltage gets below 14.8 and then land. When I land, my mah reading is only at around 3000mah and the voltage bounces back up to 15.2 or so. Should I continue to fly when my battery gets below 14.8v? What is the minimum battery voltage UNDER LOAD? not resting voltage just while a load is applied? Thanks for the input! Last edited by noxnflame; Dec 10, 2012 at 09:51 PM.
