Value external battery

Hi there, for fathom X card what are the max value in mA acceptable for external power ? can i use a battery Lipo ?
Can you show me some battery exemple

Thanks for your answer

Best regards

Hi the Fathom X will draw 2.5 watts, but you can use any battery that can supply 2.5 watts or greater. 2.5 watts is not very much, so probably any 3s or 4s (12-16V) lipo battery that you get will work.
