I just bought 2 of theses, 1 of each. how much run time can I expect out of one charge, also where can I get extra batteries.

thanx

aint scared · 11-28-2005, 07:42 PM

the stock batteries dont last too long, they are 600 mah. i just switched mine over to rc18t electronics with an 1100 mah battery and get excellent runtimes. not sure if you can use an 1100 with the stock electronics or not. i switched mine to a high torque servo so i had to do the switch anyways. i might have a couple xtra batteries that i wont need. i'll let you know. cam.

I was a WM looking for a scorpion, ( i have a jeep) and found some discontinued TYCO 7.2v battery packs and chargers for $3, yes, $3 !! they are made of C-cell size batteries arranged end to end in 2 stacks of 3. I turned it on its side and used the Dremel to cut the "transmission tunnel" and center of the dash out. i put velcro on the bottom of the battery just to keep it from rattling, the body holds it in very well. Anyway, after a full charge it will run for about AN HOUR AND A HALF. I actually got tired of playing with it before the battery died! that is a first for r/c 's I went back and bought 2 more of the TYCO packs and chargers.

Run time mabey about 30-45 min. I'm not sure on stock electronics.

I made my own pack out of rechargeable ni-mh. They say 2500 mah. I havent got a chance to test them fully but they do work.

TBItoy: How is the performance with those. They have to be hella heavy. Does it have a super high center of gravity and flip easy?

TBItoy · 11-30-2005, 03:16 PM

No not that i notice it. I did a belly up as far as i could without remounting the suspension. And then lowered it till i have about 3/8 inch compression left in the springs. i will charge up the stock battery and put it under the dash (I modified so it would fit too) and see if it makes a drastic difference. Oh, i ran it last night for 2.5 hours!! It seems to be getting longer run times with more cycles.

floogldood · 12-12-2005, 03:50 PM

Normal operating current 3.8 amps
Normal operating duration 25 minutes

I am doing preliminary testing now and will update with AAA batts also on my findings. My stock battery is usually over 650 mah and works well.

AdamF · 12-12-2005, 04:33 PM

Last run with my stocker, crawling over random stuff inside the house, I got 17 minutes before it started to slow down, and 2 more minutes until it stopped working completely. So that's 19 minutes. This was run in low gear the whole time.

TwistedCreations · 12-12-2005, 04:40 PM

I usually get around 1-1/2 - 2hrs of runtime from both of them I have.

AdamF · 12-12-2005, 04:44 PM

Wow...with the stock battery? how the heck do you do that? I charge mine with my Superbrain 959 charger that I use on all other rc batts, at a charge rate of .5 amps (anything higher and it false peaks)

floogldood · 12-12-2005, 04:49 PM

I just got thru climbing in the house, low gear only and got 35 minutes. No stopping other than to flip it over.

I am chargeing a 7 cell 700 mah pack of AAA right now.

Really??? I use the same charger @ 1amp with the normal 5mv per cell threshold and I never false peak. I get at least 30min+, after that I get bored so I don't know how much longer it would go.

floogldood · 12-12-2005, 04:58 PM

I've been chargeing at .5 - 1 amp and getting around 750-800 input, haven't discharged test (just in the truck) If I used 600 mah and 35 minutes it was a average discharge of around 1 amp. Did I figure that right?

AdamF · 12-12-2005, 05:27 PM

OK..I just charged it again, .5mv, 1.0amp, and it took 4 minutes start to finish. Is it fully charged? Or did it false peak? The battery pack is still cold to the touch, not even warm.

Nope...that diddnt work. Only lasted 5 minutes on that charge.

I usually have to restart the charger twice to get a full charge.

floogldood · 12-12-2005, 06:49 PM

1 amp should take around 40 minutes to deliver 650 mah.

floogldood · 12-12-2005, 06:51 PM

stock pack weighs 112 g
7 x 700 AAA weigh 106 g

I just tested the run-time on the first charge and found a bad cell, it ran 21 minutes and all the other cells had around 100 mah left. I just made a new pack, put a chargeing jack on the truck cuz I am tired of unplugging batteries and taking off the batt door.

Mad Scientist · 12-12-2005, 08:06 PM

So far, I have only run the stock pack, charged with the stock charger. I charge it for 5 hours

, and that gets me around an hour or so, depending on how hard I crawl.

floogldood · 12-13-2005, 09:30 PM

second run with 7 AAA was around 17 minutes, all low gear and constant climbing and crawling. I found out too that my cells are only around 500 mah (they are supposed to be 700)

650 mah at 3.8 amps is 10 minutes right?
