G+_Oliver Jackson Posted July 22, 2015 Share Posted July 22, 2015 Any recommendations for a battery charger, the battery I'm getting is a 3s 1500mah 35C lipo http://www.hobbyking.com/hobbyking/store/__34631__ZIPPY_Compact_1500mAh_3S_35C_Lipo_Pack_UK_Warehouse_.html Also, any general tips for safety, is it worth getting one of these: http://www.hobbyking.com/hobbyking/store/__74052__Turnigy_TGY_AVT01_Voltage_Sensor_UK_Warehouse_.html Is it the case that things like phones that use lipo batteries don't need this because they already have the circuitry? So the components won't draw so much that the voltage levels become unsafe? However with quad copters you have no such circuitry and going below a certain voltage damages the cells? Just curious that's all, this community is so awesome, really helpful and always full of great ideas. Cheers. Link to comment Share on other sites More sharing options...
G+_Michael Heinz Posted July 23, 2015 Share Posted July 23, 2015 For a charger, I've been having success with a clone of the IMAX B6: http://www.amazon.com/gp/product/B009VCBC2I?psc=1&redirect=true&ref_=oh_aui_search_detailpage But if you're shopping at HK, they sell a "genuine" IMAX here: http://www.hobbyking.com/hobbyking/store/__58285__IMAX_B6AC_V2_Professional_Balance_Charger_Discharger.html For monitoring the voltage, that sensor you linked to is a telemetry device that only works with certain transmitter/receiver combos. If you're using a KK controller it already has a voltage sensor, you just need to wire it in, it will emit a loud beeping when the voltage drops below a configurable threshold. Otherwise most people seem to use these: http://www.hobbyking.com/hobbyking/store/__18588__HobbyKing_8482_Cell_Checker_with_Low_Voltage_Alarm_2S_8S_.html Link to comment Share on other sites More sharing options...
G+_Oliver Jackson Posted July 23, 2015 Author Share Posted July 23, 2015 Michael Heinz For long term storage I'm a little confused. The pack I'm getting is 11.1V, however it says that you should store it at 3.8-3.85V per cell that's 3.8*3 = 11.4 so isn't that larger than the voltage of the said battery am I missing something here?

G+_Michael Heinz Posted July 23, 2015 Share Posted July 23, 2015 My understanding of how/why they label the batteries is a bit limited - maybe someone else can expand on this? But In reality the voltage will vary depending on how charged your battery is, up to 12.6V. From my own recent conversations about "how do you know if you're discharging your battery too much" 11.1 might just be the lowest charge you want to have to keep your battery in good health.
