I'm fairly new to electric and just bought my second set set of LiPo's and would like to standardize my connectors. Airplane is a Reflection with a Rimfire 22m-1000 and 3-cell liPo's. I believe it is pulling around 6 amps continuous and maybe 8-9 in bursts. My present GP 640 mah 3- cell has a JST connector on the charge side and I believe a "micro connector" on the discharge side going into my 8 amp ESC. I just bought a couple of new packs and would like to know if I could modify the whole setup to use JST connectors ( my new batteries are equipped this way ) - this was my plan until I just read that they would only be good to 2-3 amps. If they are not heavy enough, what connector would be recommended for this setup?
Thanks

Less than 10 amps would be a "JST" type red plastic connector. These are soldered on using the wire "pigtails". I am always looking ahead in this hobby and started using the e-flite 3.5mm "bullet" connectors on all my planes. Good to 30amps, but not polarized (you can connect them up backwards and burn up a battery or a plane). They are cheap and work for me. I don't see the advantage of the deans "micro" over the JST.

I can think of some advantages of Deans Micros over JSTs.

1. Deans Micros are rated for more current than JSTs. By the time you get to 8A or so, the JSTs are will start to heat up and increase in resistance. Deans Micros are good to at least 12A.

2. JSTs usually come with small-diameter wires already attached. With Deans Micros, you can attach any size wire you want. I've even used them with 12 gauge wire.

3. Deans Micros are available in a 3-pin version, making them handy for connecting brushless motors to ESCs. There is even a non-polarized 3-pin Deans Micro, so to reverse a brushless motor's direction of rotation, you just flip the plug 180 degrees.

There's nothing wrong with Deans Ultras or with bullet connectors, either. But I find the Deans Micros to be great for applications in the 10-12A range.

i am looking on going from a deans to something smaller on my 2/3 cell lipos.1500mah. How do you soughter something like a mini deans! there so small! i have trouble sougohtering the regular one! am i doning it al wrong?

Where might one obtain the 3 pin Deans connectors? I use the two pin for the battery and speed control and had wished that I there was a god connector like this for between the controller and motor. I am going to be running more like 19 amps, so the Micros might be a bit small?
