power drain issue or battery issue?

Postby mellogrfx » Sat Mar 26, 2016 1:57 pm

using 10,000 mah pulse battery fully charged and getting only 3 to 4 minutes of flight time. The batteries have been stored for about 2 years with proper discharging. A friend tested a battery and it's good. What would cause this power drain? We are going to test today with a WattsUp tester. Would like to hear from you guys if this problem has happened before or any ideas? thanks in advance.

What do you mean by tested the battery, was it a load test?
How much charge needed to replenish?
Battery voltage after flight?
Batteries lose their capacity over time, storage charge is about 50%.
Flight controller battery detection levels correct?
