16 cycle old SPC 4400mah 60c 2s shorty lipo pack with removable leads and dean's connector. This is an excellent battery, I just have one too many. It was used in a 17.5t buggy, 5 minute qualifying and races. It discharged about 900mah per run. It never got hot (just warm) and is not puffed or damaged in any way. Dimensions are 95x47x25mm and the charge rate is 2c, so 8.8 amps.
