DJI Phantom 2 - buy a battery or fix it?

Question

Batteries

Good afternoon! Several months owner and user of a used Fantom 2 v.1.0
Purpose:
More flight time. I found out on the Internet that the phantom 2 with my configuration can fly for 15-18 minutes, and mine flies no more than 10.
1)Find out what's wrong with my batteries and restore if possible. (it can assemble 1 normal out of 2 or buy more cans and replace the damaged ones).
OR
2) Purchase a 6000 mah onbo battery or equivalent. There are tips or warnings for non-original batteries.
(I fly at a temperature of 20-30 degrees and humidity 60-80%)
Battery problem:
I have 2 used batteries that came with the quadcopter (see pictures):
number 1 - flies 8-10 minutes
number 2 - flies 1-3 minutes
Regarding the first battery, my assumption is that the vital signs are not the same (83%), and therefore it does not allow me to count on more
. But what about the second? 93% do not say that it would be swollen. My last flight on it was 1 minute. There wasn’t even enough charge to fly home - the quadric just sat down.
I give a photo of the appearance and life indicators. The first one has one bar blinking, and the second one is all on. Copter
configuration Boscam FPV TS832 TX 600mw iOSD mini zenmuse h3-3d gopro hero 4 black clover antenna immersion rc fat shark Standard propellers Software versions: main controller ver. 3.14 Battery ver. 2.0.0.0 h3-3d imu ver. 1.0.0.12 P330CB ver. 1.0.2.10

ps check the operation of the copter with a normal new battery there is no way
pps who has how many copter flies on average with a similar configuration
ppps is there any point in carbon propellers? Will they increase my flight time - by how much?

Thank you for your attention!

Answer 1

1) The battery cannot be repaired or supplemented, use 2 different ones or the same ones with different wear.
2) Under the condition of a bunch of body kit, a shorter flight time is quite normal.
3) The real amperage is usually lower than the stated one by 10-15%, especially if the amps are Chinese.
4) Not the original battery IMHO fairy tales about a bull. The main thing is that the performance characteristics match (first of all, the number of cans, i.e. voltage). The only rarely are batteries with a chip, but I have not heard this on models.
Quadcopters do not fly for a long time - watch videos on YouTube (for example, about Inspire for 300 tyr). Too inefficient use of energy. On average 10-20 minutes, as far as I know.

Answer 2

Better go to forum.rcdesign.ru or to English rcgroups
And then you have a lot of questions, and there a lot of things have already been painted.
In short, any VMG (propeller group) has an optimal weight and supply voltage for maximum efficiency. If you have gone beyond the standard weight for a phantom, then you have gone all out with the search for a new optimum for weight / prop / battery / motors
