Now With Balance Function For Li-Po & Li-Fe ! 

The Hyperion EOS Sentry is a clever device that can show you the condition of your battery packs. It can be used with the most common battery types used for RC modeling, namely:

• LiIon (Lithium Ion)
• LiPo (Lithium Polymer)
• LiFe (Lithium Ferrite)
• NiCd (Nickel Cadmium)
• NiMH (Nickel Metal Hydrate)

For Lithium based types (LiPo, LiIon, and LiFe), it will work with pack sizes of 2S to 7S and for NiCd and NiMH packs it supports 4 to 7 cells.

There is no battery inside the EOS Sentry, it is powered from the battery pack you connect for testing.

When you connect a pack to either of the two connectors (only one at a time) the EOS Sentry will display the total voltage and an estimate in percentage and bar graph showing how full the pack is.
