Know your packs!  The EOS SENTRY is a quick, convenient, easy-to-use device. 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 make it easy on your eyes.  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.

This new version 2 now includes a balancer built-in so not only can you check the balance, but you can automatically fix the problem. 

Discharge of LIPO in particular beyond 80% of capacity is sure to damage them.  Be sure to use the EOS Sentry after flights (or laps) from time to time. If you see 19% or less capacity remaining, reduce the Transmitter timer until at least 20% is shown remaining at the end of each flight or race.

2.0 EOS SENTRY簡介
Hyperion EOS Sentry是一個可以檢測電池狀態的儀器，分別為：
LiIon (鋰離子)

LiPo (鋰聚合物)

LiFe (鋰鐵)

NiCd (鎳鎘)

NiMH (鎳氫)

在鋰電池方面（LiPo，LiIon和LiFe），EOS Sentry可支持2S至7S.。至于鎳電池方面（NiCd和NiMH），EOS Sentry可支持4S至7S。
EOS Sentry獨特之處是不需使用電池，而是由下連接的電池提供電力。
當下連接電池時（每次只可使用一個連接插頭），EOS Sentry會顯示電池的總電壓和電池總電量百分比以及條形圖。
