So I have a complete full battery of a 3rd gen that I wanted to see if I could learn how to recondition modules with, I cannot afford the pricey Prolong chargers so I opted for RC/Hobby chargers. I got a Quad CQ3 charger, Quad Hitec X4 Plus and 2 Tenergy T180 (not using these at the moment) for pretty cheap off of FBMP. So I will started the process 06/16 and 1 week later I have been able to recondition 11 cells and have 2 bad cells. My settings on both chargers are: - 3 Disharge/Charge Cycles - Capacity set @ 7500 mAh - Discharge at 1a / 6v cutoff - Delta Peak Sensitivity DEFAULT - Targets: 5000 mAh low / 7500 mAh (If both are NOT met, I do another cycle. Some have reached the desired target and others have dropped, for example 2 cycles, the discharge does not reach 5000 min but hits CAPACITY of 7500 mAh twice and on the third try to attempt at reaching 5000, the CAPA drops below the target and am left with a cell where neither is hitting its targets now) All in all with these settings I have been getting good results However, voltages from the charger to the actual battery terminals vary by as much as .12v and that has caused early dicharge and charge cutoffs. I tried to remedy this by making my own cables and same issue. I have copper ring terminals on the module and gold plated screw on banana clips into the chargers using 14g cable and now off by .06v-.07v. 2nd issue may be linked, as the cutoff times vary and most never reach the 6v min while discharging. I have been 20 points from reaching a target and the voltage on the machine reads 6.40v and it will stop and rests for the charge cycle. I have searched high and low and no answer anywhere online as to why this happens abruptly and machines choose to ignore my settings. Finally, all in all, I am enjoying this project and am logging all the data in hopes to then put this battery to use on my gen 3 then recon the on in the car now. I do think I will look into investing in the prolong once Im ready to do the next as this is def very, very, very time consuming and almost feels like caring for a newborn since yo u have to be attent to the temperatures, end cycles, data and so on. All ideas, improvement comments, tips welcome.
