Sorry, should be 2 in parallel of course... But 1 of these cells can be charged 2c so 100 mah or 0.1 amp which most HK Lipo balance chargers (check the website) will or should be handle. Happy flying !
I have 2 digital scales, and one showed 1.8, and one showed 1.9. I don't think it's that important. I mean, maybe if you are building a super nano with a 2 inch wing span, but than the batteries aerodynamics would screw it up.
as you can see in the description they are rated at a charge rate of 2c that means you can charge at 100 mah 1c rate which is 0.1 amp. most if not all variable lipo chargers support 0.1 amp increments in charging. i know my 4 button hobbyking charger will.
tiny little cells, but a little difficult to use due to the weak solder tabs which want to separate from the battery. Also a bot expensive considering you can get cells with twice the mah for the same price.
