Discharge Test
A discharge test was performed using the SkyRC Max B6 charger. In order to get the test to run to completion, we had to disable the Capacity Cut off and the Safety Timer (See appendix).
The discharge test revealed that the battery had a capacity of 6579 mAh (6.6Ah) as opposed to the expected 80Ah. We are only getting 8% of the rated capacity!

Next Steps
We will check the water levels in this battery and if they are low, we will top up with distilled water.
