Title: Batteris again?
Post by: NOOBinDistress on May 28, 2007, 05:05:39 PM

I ordered the 6 volt batteries from the link admin showed me. but in the mean time I still have that 6 v battery pack that you said you could solder any wires onto, and I found some soldering paste stuff that is supposed to help make it stick to stuff. If i do this do I just use the regular 22 awg wires I have been using the whole project to attatch it ?????

That or a little bit thicker wire will work fine.

You might want to consider "stranded" wire (as compared to solid core wire") as it will be less likely to break as you bend it over time.

didnt you ask this question already? :P

I used 26 gauge solid wire for the $50 robot board... I wanted flexibility but I didn't even think that stranded would give more flexibility at thicker gauge. Is 26 gauge too thin for the robot? Will I ever exceed the 2.2 A rating with (for example) 4 hs-322 servos and a handful of sensors (photoresistors, IR, sonar, etc)?

you may exceed these ratings, its better to over estimate than under estimate. you can add a big cap to help out maybe?

I prefer 22-24 gauge.

As for gauge to current rating, see the chart:

this is a decent link to an NEC table that will help you with wire info. The ampacities are based on the safest Amps to keep the insulation from melting well within standards. THHN or something similar is what you mostly find laying around. If its anything smaller that 18 AWG u dont have to worry that much about what type of wire u use beyond what Admin and the others say about stranded.
