Nigel R Posted January 23, 2019 Share Posted January 23, 2019 3.0V is complete dead flat, 4.2V is full, but for any kind of reasonable lifespan you probably want to derate the lower end quite a bit, 3.7V nominal would put the conservative 0% mark at 3.2V. Note low voltage cutoff is normally at 3.0V (soft) and a bit lower (complete) on our ESCs. Derating the high end is easy enough with most chargers, you can turn them down a bit from 4.2V (I set mine just a tickle lower at 4.16V). If you only go down to about 35% each flight I think you just about double the charge cycles you can expect from the battery. The chemistry used in our main flight packs, I believe, is LMO (although I am not a chemist, so the usual disclaimers apply): https://batteryuniversity.com/index.php/learn/article/types_of_lithium_ion Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted January 23, 2019 Share Posted January 23, 2019 The LVC operates at a preset voltage measured under load - very different from the "resting" voltage... Quote Link to comment Share on other sites More sharing options...
