Customer Questions & Answers

  • By  sauer1911 Sep-10/2015 12:09:10

    Question:
    Can I use it to test a LIPO Battery with 7,4 Volt and 20/25 Cells? If yes, since I use the battery to play with an Airsoft Electric Gun, can I hold this product attached to the battery when I'm using it (playing softair), so I'll be advised when the battery is too low to continue using it ?

    Reply:
    Hi sauer1911, It is suitable for all 2 - 4S Li-Polymer battery. Hope you enjoy shopping here with us.
