CNHL
The standard 5-inch freestyle pack: 22.2 V, 1300 mAh, 130C, XT60, sold in pairs.
Six cells at 1300 mAh is the 5-inch freestyle standard, and it is a standard for a reason: it is the point where pack weight stops helping. A 1300 pack weighs about 223 g, which is roughly a third of a loaded 5-inch quad, and going to 1500 mAh buys maybe twenty extra seconds while making every direction change lazier. Three to four minutes of hard freestyle per pack is what to expect, which is why nobody in this hobby owns two batteries. Six is a starting inventory; eight is a comfortable session.
The 130C continuous rating is marketing arithmetic taken literally (1.3 Ah times 130 would be 169 A, which no 1300 pack sustains), but the number still ranks packs against each other, and CNHL's Black Series has earned its place as the value default by holding voltage under punch-outs rather than sagging into an OSD warning halfway through a line. Burst is rated at 260C and charge at a 5C maximum, which is 6.5 A, though 1C to 2C is kinder to cycle life.
Connectors are XT60 on the output and JST-XH on the balance lead, both of which are what your charger and your build expect. Dimensions are 48 x 33 x 77 mm, which fits the battery pad on any standard 5-inch frame with a normal strap.
Treat these as the hazardous item they are. Charge in a fire-resistant bag on a non-flammable surface, never leave a charging pack unattended, and store at 3.8 V per cell rather than fully charged. A pack left at 4.2 V per cell for a month will puff, and a puffed pack goes in the disposal bucket, not on a quad.
Add the Black Series 1300mAh 6S 130C LiPo (2-Pack) to your build and see how it enhances your platform.
