Solder tabs/tags

Recommended Posts

Skip

I will shortly .......... be soldering a couple of 18650's together to make a battery pack for my glider. Solder tabs have a few options.

How do I find out what weight tab (2.5g, 3g, up to 18g???) is appropriate for 2900mAh 3.7v cells times 2 in series to give 7.4v output.

Where can I get some that don't have to be shipped from HongKong or the States??

 

Ta very much

Do you need special tags ?

You only need wire that is as thick as any other wire (on your switch) that goes between your battery and the receiver, although I would normally use something a bit thicker.  A bit of 13Amp mains cable stripped down to one of the wires, and maybe with the insulation off depending on your needs, never bought a solder tag in my life.  8-)

Mike Shellim has an excellent article on his website showing how to make up battery packs.

Mike ,we mainly go up on honey hill at cold ashby, its not to far from us ,we have a flat field that we fly from when the weather lets us , also up to ivinghoe a couple of times, we have talked about trying out more sites but getting all three of us together and the weather right seems to be impossible at the moment

I've decided on just using wires now. I think it's a bit easier as they are more flexible when you want to heat shrink the pack.  As John says there is no need to go thicker than the rest of your power wiring.

 

Here's one I did recently. I haven't put the balance plug on yet.
