Hyperion EOS SENTRY multi tester

[McKrackin]

This is the Hyperion EOS SENTRY Battery Checker. Know your packs! The EOS SENTRY from Hyperion is a quick, convenient, easy-to-use device. The EOS SENTRY is compatible with Lithium based batteries from 2S to 7S, and supports Nickle based batteries from 4 to 7 cells. It shows at a glance the remaining capacity in your battery pack, cell balance, and other information you need to get the best performance and reliability from your batteries, and avoid costly mistakes. The large LCD display and capacity graphs are easy to read, and the low price of the SENTRY compared with the high cost of batteries make it a sure money-saving addition to every toolbox at the flying field, boat races, or car race track.

Here's my take.
This is a super accurate and handy tool for me.
My RX pack on my Trex 500 will pull off about 18 flights so I needed some way to check it from time to time and this worked great.

I use it on my 2S,3S and 6S packs and it tells me things I might not want to know.Like the gap between the highest charged cell and lowest.The average of them all and available energy.

It reads out in % that make sense to me.If it says there is 20% capacity left,that means 40% actual because it factors in the 80% rule.

Love it.Got it at my LHS.

Daves review of the Align tester made me think I should share.

Wish I could take the credit there McKrackin but it all belongs to a guy by the name of Ashley Davis, as stated in the review. This guy has done a lot of reviews on several items and makes for good reading.
