Hi,
My bike helmet has two WF-501b ; white looking forward , red flashing back.
I don't like pulling the cr123a batteries for charging and I'm looking for a way to bring
the connections outside so I can charge the batteries in place.
I have an external charger that does 1,2,3,4 batteries in series, so
I'm thinking that a small mod to the cap would gain access to a 7.4 volt increments instead of each 3.7.
This issue must come up so I'm looking for some tips but I don't know what to call it.
Thx,
