Rufat AVerified owneron iSDT BG-8S Smart Battery LiPo Cell Checker

I purchased iSDT BG-8S battery checker and it was delivered quickly from amain and the shipping box was nicely packaged. The unit came in a small box with instructions, stickers and a screen protector along with the BG-8S. The small unit delivers on all of the functions as described. It can be used as a rx tester (PWM & S.Bus), balancer, cell voltage meter and a USB charger. I have been using this with 3s and 6s batteries and it works great. The unit is intuitive and really easy to use. I recommend this product compared to other cheaper alternatives that are just cell meters. I had a small issue with this unit because the film that is on the screen that protects it is really hard to see and peel away so at first I thought there was no film on it and was disappointed that my screen was "scratched" turns out it was only the protective film that I was looking at. I was contacted by John from customer support who looked at another unit to double check that the screen indeed had a protective film on top. After checking his stock he quickly got back to me and encouraged me to take another look at my screen, he also stated that he would be happy to replace my battery checker if I wasn't satisfied with my purchase. I am very satisfied with amainhobbies, their staff and their products. This company is great to deal with and is my first stop for all my RC needs. Thanks again!

Finally upgraded my battery checker, no more pressing buttons to check the voltage of each cell as it shows everything at once. Quality seems good so far, it did come with a screen protector like another reviewer on here mentioned.

Gabriel Bon iSDT BG-8S Smart Battery LiPo Cell Checker

Great battery checker! The accuracy is on point and the USB works as expected. However, the screen protector can be finicky to install as it’s made of plastic, and the screen itself scratches VERY easily, so be careful.

Made the move from an analog display cell checker to the iSDT BG-8S. This little thing is awesome and feature packed. Wait until the guys in the pits see you running your usb fan with it, keeping you nice and cool while tuning/wrenching in between races. Oh, and checking your lipo cells ofc.

What reviewers say

Reviewers generally rate the iSDT BG-8S highly, describing it as accurate, easy to use, and feature-rich. It shows all cell voltages at once, which reviewers prefer to pressing buttons on older checkers. Functions mentioned include RX testing (PWM and S.Bus), balancing, cell voltage metering, and USB charging, with one reviewer using it on 3S and 6S packs. Packaging and delivery were praised by one buyer. Recurring complaints concern the screen: the protector is plastic and hard to install, the screen scratches easily, and the film is hard to see through. One reviewer noted that no printed manual is included and the manual must be downloaded from the manufacturer's website.
