Battery question

[HumboldtBlazer]

Which batteries go dead first if fresh ones are put in at the same time? The transmitter or reciever? I would think the reciever because it powers servo's right? My transmitter has a digital readout of the voltage of the batteries. Fresh is 12.5 does anyone know when the signal is too low to send signal to the reciever. I have been changing the batteries both reciever and transmitter at 10.8v read out on the trans am I wasting batteries?

on the manual of my JR radio, It says to change the batteries at 9.5 or something in the 9's. I have a failsafe and a Throttle Return Spring on my carb so just in case i do run out of batteries, either the breaks wil go on or the spring will bring my car back to idle.

Well actually mine is not a spring. It is a rubberband around the slide and the carb. :classic:

you'll be fine even at 9v in your radio but that is about as far as you would want to go. My new JR XS3 has an auduble alarm that goes off at 8.9 v or lower. USUALLY your rx pack will die first because it is driving all the mechanics of the car. The first thing I do is invest in some rechargable Rx batteries and a tx pack. Buying AA's every other day sucks!

I think my flat pack paid more than its share of regular batteries in the first month I bought it. That would be my first investment when buying a new RC.

The receiver will eat batteries much more quickly than the transmitter; you are correct. As for the when on changing batteries, I change my receiver batteries after about four solid bash sessions. That seems to be the drop dead time for alkalines and amounts to about 8-10 hours of run time. I have rechargeables in the transmitter, and I charge it to capacity before each session.

Thank you SkyMaxx!

Get NiMH batteries instead of NiCd batteries, they cost more but are well worth it.
