DC7-55V Li-ion Battery Level Indicator Tester – LED Voltage Power Monitor Panel
About this item
Hey, if you're into DIY electronics or just want to keep an eye on your battery packs, this little LED indicator is super handy.
It's a brand new DC voltage power monitor that works with anything from 7 to 55 volts – so think Li-ion packs, SLA batteries, power supplies, you name it.
The display is a clear LED bar graph that shows you roughly how much juice you have left.
No complicated setup, just wire it in and it's ready to go.
It's unbranded, but honestly, for the price, it's a solid little tool to have in your workshop.
Perfect for custom battery builds, solar setups, or just checking if your batteries are still good.
