battery monitors

[MILLER4PRESIDENT2020]

ive seen several pics of peoples phantoms with digital gauges that display the battery levels. Any ideas on where to find these? do they weigh a lot, or steal a significant amount of power themselves? Do they usually just plug into the smaller unused terminals of the battery because I have a headlight on mine that already uses those.

I always just set a timer for about a minute less than the usefull flight time of the battery but I am afraid someday I will accidentally put in an uncharged battery, or have a weird discharge rate and then it just cuts out at the most inopportune time, like over water or on the edge of a cliff because murphy's law you know...

Those and most any other LiPo checker like that will connect to the balancing (small) plug on your batt, so you may need to get a splitter cable (or make one) to be able to use that at the same time as your light.

Another option is to add a Tx/Rx system that gives telemetry data such as battery level. This can easily be done for less than $100 and can be very valuable when the aircraft is too far away to see/hear the batt checker.

EDIT: Here's one more style: http://www.dslrpros.com/Products/tabid/ ... fault.aspx
