Help!
battery connector

hey folks....

I got 2 Turnigy 5000mAh 3S 40C Lipo Pack
then here comes the problem.. I cannot find a suitable connector... I want to wire 2 connectors to the power distribution board so that I can connect the battery directly, with out a dean adapter.

the spec on the HK says it needs 5.5mm bullet connector... but what I can find all around are all 3.5mm or 5mm... there just seems not 5.5 around.

what should I go for to get this done?

can some1 help me out on this..

Looks like battery probably has 10 or 12 AWG on it. What you "need" depends on how many amps you plan on pulling. Also look at the related items on the battery page, here's the connectors:

Here's a charge lead which has 14AWG wire on it:

is it a good idea to cut that banana connector out and solder the wire onto the power distribution board?

That would be an option if you wanted to do minimal soldering. However as I said it's only 14 gauge wire. Since you have not said what your application is, such as how many amps or what kind of power distribution board you are connecting to we can't tell you if that is sufficient.

You'll need at least 12awg wire, 14awg is too small for 80A. You said you have those two batteries now, I would use connectors based on what you plan on buying for batteries in the future. The nanotech and gens ace come with HXT4mm and those connectors are easily found from many vendors and though at the top of the range should handle 80A. If you think you will always buy the regular Turnigy then order the 5.5mm it uses. I don't know about you but I don't like replacing my battery connectors all the time.

I will probably stick with those 2 big junk for a while.... so probably I should stick with the same size plug so it is easy to replace.....

I heard about people using dean on power board side and use different size adapter for battery... But wont that be bad practice cuz the adapter might be a bottle neck/weak point?

Every connection adds resistance / waste in the line. To some people getting every bit of power out is really important.

I imagine Deans would work, but pulling that much power I would use the real thing as most of the knock offs are only rated 60-70 amps.
