Re: A123 + Reg Arceenut is correct. If you put your input/output of your regulator on an oscilloscope, with a variable power supply on the input, you will see as you increase the voltage on the input to 7 volts, you will see a corresponding rise in the output until the input side reaches the minimum input voltage of 7 volts, at which point, you should see your 5 volt output. As you increase to an input of 15 volts, you will maintain the 5 volt output. EDIT: I just noticed that somehow, I missed the entire second page of this thread LOL. |

Re: A123 + Reg Hi iwannaknow You know it doesn,t surprise me at all  Thanks for relaying that info Michel |

Re: A123 + Reg Rcexl Optical ignition kill (up to 20v at 3a) Hobbyking (turnigy) 5/6v regulator 3a, 5a max, set to 5v (switching regulator). Please bear in mind, i'm not telling you what to use or what to do, merely suggesting that the voltage drop may be the result of the kill switch, nothing more. Re-configuring your setup so that the regulator is after the kill switch should not be very complicated and will not cost anything. If the results are no better, nothing lost. If you choose to ignore my suggestion you are not offending me. Good luck and Happy flying. |

Re: A123 + Reg Hi Thats all fine ,.................. it still doesn,t tell me what regulators youre useing and what type of kill switch . Michel |

Re: A123 + Reg i use the same setup on all my planes. 1x 2S1P 2300mah A123 (6.6volts nominal) through a heavy duty slide switch for reciever and all servos, i use 2 sets of wires soldered at the battery to the slide switch, use a 2 pole switch (one pole for each of the positive wires), from there two wires to the reciever (one goes into the battery port and the other Y's into a servo port , i don't use any power expanders or anything like that. 1x 2S1P 1100mah A123 through a slide switch, ignition kill and 5volt regulator for ignition only (single set of wires for ignition). i charge the batteries through the balancing ports. i'm using 4 futaba recievers (617) and 2 hobbyking orange fasst compatible recievers. all of my A123's were bought here from offroader who harvests them from dewalt battery packs and i wired them as 2S1P as we're only talking about six airplanes running this setup for 3 years or so, i can't say this is bullet-proof, but i can say i have not had any problems at all with this setup. (i was into nitro and nimh/nicad before i went to giant scale ... thanks but i'll pass on electrics until i HAVE to) |

Okay I,ll bite ,..................... what are you useing ? ( you didn,t mention that ) BTW ,.... I tried it on a 3S lipo , and got 4.9 volts , "BUT " , I didn,t use the ignition kill , nor a switch This is interesting to say the least Michel |

Re: A123 + Reg before you spend any more money on batteries you may want to try to swap the ignition kill and voltage regulator (batt, switch, ignition kill, regulator). the ignition kill uses an electronic switch which will inherently drop some of the voltage. if the results are the same go for the battery. on another note, i'm running a zdz40, jc28, 2x dle30, 2x evo58 and i haven't ever put back more than 100ma into the A123's after 45minutes of flying. (mainly sport flying, aerobatics and some 3d) just a thought. |

Re: A123 + Reg Perhaps not. Check to see if the output is maintained with the supply from a 2S LiPo pack, then compare weights and dimensions with a 3S LiFE pack if that is an important factor. |

Re: A123 + Reg Hi You guys found the problem . The input was too low . I made a connecter from a female rc terminal , to banana plugs , connected the banana plugs to a 12 volt battery , and than to the regulator , and than to the ESV , at 1.5 amp . BINGO ,..................... it held at 4.9 volts , now this is acceptable  I need a three cell pack . WHOOPI ,......................... Thanks guys Michel |

Re: A123 + Reg Hi Good morning hey ,....................... I think you guys hit the nail on the head . I didn,t notice that the input had to be 7 volts . I only have 6.6 . I,ll give it a test Michel |
