Default 25 minute run time battery

So i have 2 Common Sense R/C . CSR Lectron Pro 7.4V 5200MAH 35C LIPO PK XT60 W/TRX Adapter

Run on 2 different TRX-4 and about 5-7 minutes on low speed and 17-20 minutes on high speed and low voltage kicks in about 25 minutes, on 2 stock trx.

Doesn't seem right to me?

No, not even close. Did you temp the battery right after running?

Didn't you say a while back you got an hour run time from those packs?

what kind of charger you got ? do you have a balance charge provision or are you relying on the balance plug ? if you ave the ability do a storage discharge at low amp (.5 maybe ) then do a very slow balance charge .

Me thinks you're going to see your problem go away with that SkyRC charger.

5000mah lasts me about 6 hours. But I stand around and talk a lot. I also spend 90% of the time under 20% throttle.
In the snow if you're at full throttle all the time, half hour might not be so bad. Also your esc has settings for low voltage that can tell the car to shut off sooner. The cold will also lower the batteries chemical reactions reducing the voltage. Also check that the esc thinks the battery is 2s and not 3s. Usualy denoted by a series of beeps when you plug it in.

And +1 for the sky rc charger. I love my imax b6 mini
