Got my hands on a Flexvolt battery today. I’m extremely curious as to how it works so I took some voltage readings on the terminals of the battery.
[External image (uploads.tapatalk-cdn.com), not copied]
B+/B- is 19.23v
B+/C3 is 7.69v
B+/C1 is 15.38v
C3/B- is 11.54v
C1/B- is 3.85v
C1/C3 is 7.7v
TH/C1 is 15.37v
TH/B- is 19.21v
Any other combination yields no voltage.
My probes don’t fit into ID, C2 and C4 so I need to get some wire and alligator clamps.
I think the battery by itself is not going show much, I think the new flex tool has the electronics to open it up
The shipping clip is supposed to be a physical disconnect but doesn’t look like it actually disconnects anything so the connection must be initiated by the tool.
Wrap foil on your probe tips to stick it where it won’t fit.
Yeah the clip literally looks like it does nothing.
The red shipping cap absolutely does something. B+/B- goes down to zero Volts.

That’s actually not even an option, it’s required by law.
If Dewalt didn’t have the clip no flex tools could be shipped by air.
…I know that it’s functional, and what a gamechanger it is for Dewalt for shipping. I’m saying, having a couple of them on hand here it’s hard to believe that this clip is such a big deal. It LOOKS like it does nothing 😛
Browsing Dewalt media it seems it pushes a spring-loaded bar back, breaking a connection.
If you look at the battery photo in the OP, there are 2 recesses, lower down and to the left and right of terminals B+ and B-.. The Red transport clip has two tags that locate into these, and push them inwards, thus initiating the ‘disconnect’ within the battery…
