Hyperion Sentry Mini Charger, Discharger, & Battery Checker

Protect your investment by properly storing your LiPo batteries.


Sentry Mini Charger, Discharger, & Battery Checker

It's imperative that all LiPo's be stored at 3.7v to 3.8v when not in use. Any time a LiPo battery is fully-charged for extended amounts of time (this could collectively be hours, days, or weeks), the Anode inside the battery naturally oxidizes, decays, and thus longevity and cell-performance is lost.

Storing your LiPo batteries accordingly will give you more cycle-life and save you money in the long run. After multiple years of in-house development, we've released the first-of-its-kind Super Quick Discharging solution meant to discharge and balance LiPo's easier and quicker than any other tool in the market.

Finally, a "Plug-n-Forget" battery storage solution that boasts up to 390 watts Discharging power, the Sentry Mini Charger & Discharging tool is like none other. In the past, Discharging batteries took hours or days, and then sometimes these devices would accidentally over-discharge and leave your packs fully-drained due to parasitic draw while idle, but not the Sentry Mini Discharger!

Just connect the Discharge and walk away indefinitely, now there's finally a tool that allows you to efficiently and effortlessly discharge your packs without hassle.

The Hyperion Sentry is not only the most powerful Discharger tool available today, but also functions as 50 watt Mini LiPo/HvLi Charger, and is LiPo - HvLi - LiIon - NiCd - NiMh Battery Checker.

The Battery Checker will graphically show at a glance the remaining capacity in your battery packs, cell balance, cell voltages and difference between the cells. The Sentry Mini Charger and Discharger provides you with all the information and tools necessary to maintain and keep your packs performing. Avoid costly mistakes and increase battery reliability by using a high-quality battery checker.
