I spent several hours over the weekend reading threads and watching videos on Lipo batteries and took notes etc.. This is the guide I came up with and I think it is pretty accurate. I am not an expert in any way but this information is from various sources and seems to be the best overall advice. I hope it is okay to post this, I am just trying to help. ii I wanted a nice easy to search guide that new users could reference. If that exists, my apologies, I can delete this. ============================================================================ Recommended Voltages for the Typhoon H. 13.2V (3.3V/cell) Lowest voltage the battery should EVER be at. Below this the battery will most likely die. NEVER EVER let it get this low. If it is even possible on the H. 14.0V (3.5V/cell ) ABSOLUTE lowest level your voltage should ever be at to land for Lipo's in general. Below 14V is too low for good battery health, It is not recommend letting the H get this low. The warning will kick in before this so I don't think you can even run it this low thankfully. 14.3V Warning kicks in at this level but land BEFORE you ever see this warning! Some guys report that they just land when the warning comes on at 14.3V. Feel free to do this but it is not the advice from everyone. This would be the absolute minimum voltage you should ever land at with the H IMHO. Hence the warning. ii 14.4V (3.6V/cell) Reported Lipo lowest safe level for a slow speed (not pushing the motors if far away) return and landing. Consensus is to land before you even reach this level to be safe. This is the "oops I was not paying attention and need to bring it home now" level if you forgot. You can drain the battery down to this and probably be okay but with variations in batteries and other factors you may or may not have issues over time. 14.8V (3.7V/cell) SAFE landing. The recommended voltage to start landing at. This takes into account battery differences, the accuracy of the reported voltage and reading the voltages under load. Usual advice is your battery will last the longest not letting it get too much below this level. This is having about 15% remaining on the battery. Some say you can run it even lower if you want to get max flight time but I would land no lower than 14.6V or maybe 14.5V. This is more for battery health than running out of power. 15.0V (3.75V/cell) If your drone is far away from you, but still in LOS, start thinking about bringing it home at 15V, or just below, to allow enough time to bring it home safe at whatever speed you want. 15.2V (3.8V/cell ) For storage. Keep it at this voltage when not using the battery for any length of time like over the winter. For us unlucky people that have to deal with winter. ii 16.8V (4.2V/cell ) Highest voltage the battery can hold or fully charged.
