Hey everyone,

I'm having some trouble with my Pro-Range INR 21700 P42A 22.2V 8400mAh 6S2P 80A/100A Discharge Li-ion Drone Battery Pack and was hoping to get some advice
The battery used to give me great flight times, but recently, it's been draining much faster. I used to get around 20-25 minutes of flight, but now it's barely hitting 15 minutes. It seems to take longer to charge than it used to. I haven't changed my charger, so I'm wondering if the battery itself might be the issue. I've noticed some significant voltage drops during flights, which wasn't happening before. This is causing my drone to lose power unexpectedly, which is pretty concerning. I've checked the battery for any visible signs of damage, like swelling or leaks, but everything looks fine on the outside. I always make sure to store the battery properly and avoid over-discharging it. I also balance charge it regularly. Has anyone else experienced similar issues with this battery pack? Could it be a problem with my charger, or is the battery just wearing out? Any tips on troubleshooting or extending the battery life would be greatly appreciated!

Here are the details of the drone I'm using with the Pro-Range-
Drone- DJI Matrice 600 Pro

• Weight: 9.5 kg (without gimbal and camera)

• Max Takeoff Weight: 15.5 kg

• Max Flight Time: Up to 32 minutes (with standard TB47S battery)

• Max Speed: 65 km/h

• Gimbal: Ronin-MX

• Camera: Zenmuse X5R

I've been using this setup for various aerial photography and videography projects. The battery pack has been great so far, but these recent issues are starting to affect my work. Any insights or suggestions on what might be causing these problems would be really helpful!
