Review on 8 Pack AA Battery Holder Bundle With Wire - 1.5V, 3V, 4.5V & 6V Holders By QTEATAK by Brian Davis

I wanted to replace the batteries on a rechargeable handheld vacuum. I needed a new holder and this was perfect. It came with multiple configurations and for the price beats trying to solder batteries, which I hated ever since I was a kid in the RC car hobby. The only downside of this are the wires. They look like 22 gauged wires and for my application (3 x 18650) that's 12v is more than those wires should handle. So unless your application is low power, those wires needs to be replaced.Updated. After replacing the wire, the metal springs could not handle the Amp of the application. They heated us and melted the plastic.
