If I want to use 2 receiver packs, can i just hook them up to a standard "Y" connector? I found my 1100mAh pack to falling off a little and I have a 1200maH pack I can strap to the bottom. So can they both be used at the same time? Does this extend battery life? Can I change them at the same time using the charger lead from the switch?
Thanks

You can, but you have to make sure they are wired in parallel. If you wire them in serial, you increase the voltage as opposed to increasing MaH.

OK, then can I ask how to wire them in parellel? So a standard "Y" harness\connector will not work without modification?
Thanks

lstracerx is correct. Wiring them in parallel is the correct configuration. The "standard" Y connector (like the LST uses in the steering servos setup) is prewired in parallel. You could use this type of Y connector. Just be sure that the polarity of your battery (+,-) is the same with both connectors (since that Y connector is has three contacts - it would be easy to reverse). I'd recommend situating the plugs so that the neg. wire from the batts connects to the outside brown wire of the harness (your pos. wire will then be the center contact). You then would plug the single end of the Y harness into the batt. input of your receiver with the brown wire to the outside (just like the servo connections).

Always a good idea to double check your connections before switching on. Reverse polarity to the receiver could damage it.

As good as some Battery Chargers are like the supper brain, why even bother..a battery pack should last 1/2 a day if not all day..just charge it up slow over night like at .20 to .30 amps. That will place a nice long strong charge on your packs. Never quick charge therm in like 15 minutes..thats all bs. A quick charge or peak charge is crappy charge..Well from what I have done in the past...I am by no means an expert. Part of this hobby is experminting like your wanting and that is a great thing. If nobody every tried to do what you are doing then we wouldent have hobbies like this. Enjoy yourself[8D]

Why not mount ur second battery anyway and if you start to lose power on one just change over to ur other fully charged pack????
