Here is the first part of my case-control study for breaking in LiPo battery packs. I take 5 Turnigy NanoTech 2200mAh packs and break them in by charging and discharging at 1C for 3 cycles, then charging and discharging at 2C for 2 cycles. Another 5 identical battery packs will be charged fully and used immediately without breaking in.
After randomly using these 10 packs for general use among my fleet for 100 cycles each I will assess the internal resistance of each pack as well as monitor for any failures or deviation from normal service.
In breaking in these packs I also test a method of using one pack to charge another while discharging itself, plus measuring the efficiency of mAh in vs. mAh out for this charger, and the relative accuracy of the charger vs. the power meter.
Stay tuned for the future video where I will re-evaluate these 10 packs to see if breaking in makes any difference in internal resistance.
