Battery holder contact resistance measurements

I finally got some battery holders from digikey that I have been asked about several times.

BK-18650-PC2
BH-18650-W
BK-18650-PC4

Here are the results

BK-18650-PC2 Single Contact = 7mΩ
BH-18650-W Single Contact = 2.6mΩ
BH-18650-W Single Contact W/24g Wire = 16.4mΩ
BK-18650-PC4 Single Contact = 9.7mΩ
Keystone 1043/1049 Single Contact = 1.2mΩ
Keystone 1042/1048 Single Contact = 1.2mΩ

Keystone is still the winner

Best test evar cepting for neg ayds test since single..

If you don't mind and has, how about spacer magnets?

Thanks Bap

For a mech mod this might make a difference, but for a regulated mod it shouldn't matter.

It doesn't change the output of the regulated devise, but resistance is resistance and regardless its causing you a vdrop. A more resistance efficient regulated mod will allow you longer vape time because you will be draining your battery(s) further, because on a regulated mod the vdop from the battery(s) happens on the input.

Grrr got 2 mods waiting on 1048's, still on back order from mouser and no one else has em!

 

[bapgood]

1042's are back in stock at mouser, two of them is only slightly wider then the 1048.

Yea I thought about that too. My order changed from back order to pending. We'll see if they ship today/tmw.

I'm confused (what's new?). Is mΩ = micro-ohm, or milliohm or something else?

Yes....mΩ = milliohm

Sweet! Mouser order for 1048's is processing!
