Hello,
Either my web search terms are quite inadequate, or perhaps no one ever wants a conveniently pre-wired holder for batteries connected in parallel.
Tried at standard (USA) sites like DigiK-- and Mous–. The in-series 2xAA=3V, etc., are even available at general merchandise retailers as shown in this pic from an A—zon listing.
Would appreciate comment.
Exist but pretty rare or you have to solder them yourself. Here’s one I found on Amazon https://www.amazon.com/Plastic-AA-Battery-Holders-Block/dp/B01MQY5JZX
Here’s some other really cool ones that you also can attach wiring to without soldering.
