Battery issues that I don’t understand

[shortround91]

Ok went flying yesterday my buddy has just gone 8s on his 90 Raptor. He ran 2 4s packs 100c 4400 Zee packs and then a 6s 5200 80c and a 2s 5200 60c Hoova packs. The twin 4s perfect no issues but the 6-2s setup he told me 2-3 min came down at 9% but when charged the packs only took about half of the mah. So he flew correct 9% I put his 6s pack on my charger we charged and correct it only took a little over 2400mah to be at full capacity. I’m including pics hoping someone can explain how a 5200 pack down even after sag only takes 2400mah to get 100%. Thanks for the help on this guys

Use real-time mAh consumption meters (such as Smart telemetry or current logging devices) for better control.

What 2S 5200?

Real time consumption meters are NOT accurate or "real". The original post shows this.

Have you ever compared the accuracy between popular measuring devices like Smart telemetry with specialized data loggers? I am wondering which device to invest in for my FPV system, and would love to hear from someone with real-world experience like you.
