Need batteries for T-Rex - which connector???

[esrazor]

Hi,

I'm new to T-Rex helis, but I have one that is ready to go and I need to get new batteries. My questions is what type of connector do I need to look for to connect the battery to the ESC in the heli? I assume that the Lipo batteries have many different connectors for different applications - ie boats, cars, plane, helis, etc. If so, I'm confused as to what to look for when shopping for new batteries. I'm sure you T-rex pilots know the connector I'm referring to.

When looking at web sites for batteries, I can't really tell what type of connectors they have, both for connecting to the heli and also for charging.

Thanks for your help!

You're going to probably want to get some 3S LiPo's. Something in the 2000 to 2200 mAH range. Some come with connectors and some don't. The most common for this purpose is the Dean's Ultra. They typically run about $3.00/pair. But I recently bought an order of 10 pairs for $7 (I think they're actually clones of the Dean's, but they seem great). I think most are finding the hottest battery out these days is the FlightPower EVO. But if you're looking for something more economy, you might want to check these out.

DTCX10 Deans Style T-Connectors 10 Pairs (20pc) $7.08

The other conenctor on the batter will be the balance-tap. Some chargers will charge through the balance tap, and some charge through the main leads (the Dean's connector). You'll definitely need to either get a balancer, or a balance/charger.

First off, what connector is on the heli now? That would be teh easiet to use. Lipo don't come with connectors, although some suppliers will add them for an additional fee.

Dean's Ultra are probably the most common ones in helis and airplanes. Cars tend to use Tamiya plugs for some odd reason, as they are junk.

I prefer to use real Dean's as teh knock off tend to have softer plastic that deforms until the heat of soldering, and the metal spring parts tend to break and bend.
