    DUAL BATTERY SYSTEM QUESTION

    I'm running a 9cap transmitter,with a Spectrum ar 7000,a Miracle dual battery switch, running 2 Nimh batteries (1700mah).The question is ?how do I use the 2 (redundant) batteries with this set-up?Do I use a y-harness for the batteries or plug one battery into the power terminal on the recv'r and the other battery into an aux.channel on the recv'r?and will these or another combination give me the redundancy of 2 batteries packs so in the event of a failure the system will still function safely.This system is in my Comp-arf 50c.c. yak

    thank you

    RE: DUAL BATTERY SYSTEM QUESTION

    Plug each battery into an open slot in the receiver. They will work in parallel (same voltage, double the capacity), and if one gets unplugged or dies, the other battery will power the system.

    For single receiver thats the way to do it, I use two receiver with two batteries.

    RE: DUAL BATTERY SYSTEM QUESTION

    Yup, two batteries, two switches, one into a spare channel. Since you have a Futaba the DSC port is almost never used and connected to the power bus so that works too.

    RE: DUAL BATTERY SYSTEM QUESTION

    you need to fit a BATSHARE made by SMARTFLY

    If you just y lead or equivalent and one pack or even just one cell in a pack ,,paqcks it in it will drain the other pack like a dead short.

    RE: DUAL BATTERY SYSTEM QUESTION

    I have another sugestion that has worked with no problems and gives you a number of options at not cost.

    Have a look at SMARTFLY's POWEREXPANDERPRO (not sport )

    I run this system in both my 50 cc models and have set it up in my 42% EXTRA300 running 2 5000Ma 2s lipo's useing HITEC HS-7950HV servo's all round.
    My 50cc set up uses lipo's into 8amp DUALSKY regulators the Board regulates power to the Receiver 5 volts, the system then supplies clean power to the servo's HS-7955TG all round.

    These have proved to be very reliable on 36Meg. and 2.4Gig.

    Have Fun
