I was just assigned to work on a gun because it apparently drains the battery after 100-200 shots. (semi and full auto don't matter, if you ask).

So multipile tests have been done such as: Different types of batteries, Different types of chargers, Different types of mAh, etc.

Yet no conclusive results have been determined.

Some things you may want to know, there is no fuse but tinfoil in its place (as i have no idea if this will affect the charge loss).

MY theories are that: shims job is so tight it forces to motor to its limits draining the battery, motor just sucks or the spring is to much for the gun to handle.

In terms of gun upgrades I have been told that it has stock CA internals, other then a upgraded spring guide and a systema M120S(yet the guy who asked the question is not to sure on the spring).

The gun is a M15 FYI.

Just wondering what everyone has for solutions, things to look for or tests to conduct to solve this problem.

Thank you for your time, consideration and help!
