I have 2 x batts. 1 x 2800mah Muchmore and 1 x Pannspeed 3700. Both charged to full but whenever I play, both lasts at the most, 10mins. When I measure the voltage, both still carry abt 7V still. TT01D,23T motor, MC330CR ESC.

Sigh.....

You should be getting a lot longer on those batteries about 15-20 on that 2800 and 25-30 mins on that 3700.
What charger do you use? and how many amps are you charging at?

Some stupid Ansmann charger. No display. I put it on slow charge already. After charging, I always check with multi meter and it's abt 7.5V le. Battery charge is there. Problem is halfway playing car, abt 10mins, car loses power so I measure the voltage. Left abt 7V. Funny le. 7V motor like no power already.

Is it better to charge on 4 amps 2 ampsor 1? My charger has all settings and I always use 4.. Should I be using another setting?

@ adrictan
Could be that charger then i had one of those the slow charge ones took alnight to charge a battery then i got a 3hour charger with trickle when done and got alot more run time after.I got the ansmann with a combo deal until i could get a better charger,shop around you dont have to spend megamoney on a charger

@MTboy

Off course charging at 4amps will get the battery done quicker but will shorten the life on the battery some say u get maybe 1000 charges on a nimh battery pack but charging at that rate could half that,id stick around 2-3 amps unless your in a reall hurry to go

7.5 volts isn't really fully charged.

i always charge using 3.5 or 3.7 amps for my 4200mAh & above batts. not so ideal to charge at 4 amps & above. shorten the batt life span.
