4s lipos draining at different rates overnight

[mokeife]

i have 2 4s lipo boxes both of them are run with turnigy nano tech 2.2 4s lipos. The problem i am having is that these same 2 lipos in the same exact boxes are draining at different rates when not in use. for example last night one box dropped almost a whole volt and the other box only dropped .3 volts overnight. Now i know the led screen on the box is going to use some battery power but i dont think it should be almost a volt. and if so why did the other box only drop .3 and it seems to be completely random as to which mod drops the most. The only possible cause that i could think of is a dirty connection somewhere so im going to clean them tonight. i would appreciate some help here thanks

Could be anyrhong. From one mod has better solder joint than the other to the batteries are better in one to one meter meters to a slightly different scale.

How about turning the mod off.. then it should consume no volts overnight.

Kill-switch would work nicely
could even be a poor grounded leads from battery as well. any thing could make a circuit unless your battery and sled are shields and grounded properly

i do turn the mods off when i remember lol i was kinda just leaving them on as a test to see how much battery life they use. i cleaned all the contacts on both mods last night and this morning they both only lost about .2 nowhere near the volt i was losing so i think problem solved thanks for your help
