“I tested this against my field tester and it's now in my field box and my work bench. It's great at telling you what cell is bad. Not just you have a bad battery, but number 2 cell in your 6S battery is bad. It also can balance quick. I love that! But as with all Lipo battery's when you are discharging with this. Don't walk away! The device gets warm. The battery stays cool. But I never leave a LiPo alone. I recommend no one leave one alone. If you don't own a battery tester, balancer, discharged, all the size of a credit card? You should purchase this one and you'll never need another.It's very quick and easy going throught the menu. Simple. Affordable. Precise. It's what I like.”
“Works perfectly, readings match my IMAX B6 exactly.Simple to use, great instruction sheet included. Very handy for field use and a backup on the bench, worth buying two.This is a well made, Must Have Item!!!Get at least one, you'll be very happy!!!”
