Martin Dance 1 Posted April 11 Share Posted April 11 It looks like a battery checker. It dates from when nicad or NiMh batteries were used to power Rx's and servos. Simple to use plug into the Rx battery. Green LED's light, good to go, yellow LED's your pushing your luck. Red LED's lit do not fly, insufficent capacity left in battery. The more sophisicated checkers applied a load to the battery to hnopefully give a more realistic assessment of remaining charge. Quote Link to comment Share on other sites More sharing options...
Neddy Posted April 12 Author Share Posted April 12 Yes you are right I just checked my fully charged 9.9v battery and it lit up to the top green light. Thanks for that. Good to know. Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted April 12 Share Posted April 12 These battery checkers were mainly for checking the receiver pack, so typically 4.8v packs, though some slightly fancier ones were switchable between 4.8v and 6.0v packs, with a wee button to put the pack under a fixed load. 1 Quote Link to comment Share on other sites More sharing options...
