### ⭐⭐⭐⭐⭐ Great!

### ⭐⭐⭐⭐⭐ Simple easy battery protection
*by G***N on September 12, 2025*

### ⭐⭐⭐⭐⭐ Great low voltage cut off
*by T***R on November 10, 2025*

Added one of these to my kids power wheels upgrade. I put 18v milwaukee batteries on his 12v mini atv but didn't want to destroy the batteries by running them too low. Cuts off right where I set the voltage which was easy to set. I think i had to look up how to set the voltage online because i don't think they came with instructions, but it was easy.
