I just picked up a Hitec 645MG servo to upgrade the steering on my Maxx. I wanted to get a battery pack for the car, but all they had there were nicad 700 mAh (5 cell hump). Is that sufficient?
 
It all depends on how long you want to run w/ your battery pack. I use 6V 1800mAh and am able to run all day w/ no worries of losing battery power. I would assume that 700mAh would probably only last a couple of hours. Perhaps someone who runs 700mAh can tell us their run time with them.

Were you looking at 4.8V pack or 6V packs?

I would recommend a 6V pack with 1200mAh or higher. You don't want to worry about your receiver battery dying on you at WOT.

There is a similar thread going on about servo's & battery packs. Check it out...

If you need a starting point for 6Volt pack, you can check out Tower Hobbies or Ebay.

dont get a nicd battery they are crap you have to discharge them everytime you carge them if you want them to last for a while nimh's you just have to top off and your set also the higher the mAh the better
 
You are supposed to discharge NiMH packs before charging them also. They can be store with charge in them but are best charged from a dead state. It may be over kill for just a receiver pack though.:egad:
 
but it wont harm the numh's if you dont discharge them after everyuse nicd's start to generate a memory if they are not discharged nimh's dont
 
With all this charging/discharging/memory stuff it is sounding like it might be easier to just keep buying alkalines for my RX. :confused:

Is there a NiMH battery out there that fits in the stock battery holder?
 
mostly all hump packs will fit but a good one is the HPI 6v 1200mAh hump i use that one and like it very much
 
definetaly get a hump pack. Definetaly higher than 700Mah.

1200 mah should be sufficient.

I know you are supposed toi discharge/recharge. I dont do it.

Mine have lasted me quite a while. I just put it on a 1 amp quick charge before I go out to top it off. It's never run out after a day's driving. Maybe at 1 1/2 days.

If the hump pack deal is to confusoing and/or complicating. Then here's the ticket.

Go to radio shack get the new Nihm AA's the come with a wall charger and two batts. You can buy two more to fill the charger. at around 19.00 for two aa's and a charger their nice. they last longer than nicads or alkalines. You can also use them for any other deal you have the uses aa's

Me, I prefer hump pack simple, and never let me down
 
Your missing out dude you need a savage. take that old t maxx and get some money for it which would be 0 and by a savage.

Looking at name of Forum - T-Maxx Talk - take that Savage junk somewhere else.

My Battery Pack

Got my battery pack in today. I love this thing!!
 
Get a savage dude. And get a picco 26 too. then we will see who is bad then.
 
You would have to buy a the Savage at $20 more than a T-maxx AND buy a new engine to beat a T-Maxx? Just shows what's what right there I'd say.

I make my own out of radio shacks 2000 mah NiMH bats. You should use 5 cells to get the volts up to 6. If you just put 4 NiMH's into the receiver holder that is made for alkalines, you will only maxx out at 4.8V. Alkalines are 1.5V per cell, whereas NiCD and NiMH are 1.2V per cell.

Here's one of the ones I made. It may not be pretty, but it gets the job done and stays dry as well. I had to cut the top off the stock battery case for it to fit though.

this is a crude but very effective(cost and performance) way to use rechargables with the high mah. These are energizer 1850 mah 1.2v AA. Radio shack single battery holder. just splice the wires to add the fifth battery, two small 1/16" holes in top of battery box and some J.B. weld. make sure you scuff both surfaces of plastic to be J.B. welded or it will not hold.single battery holder is like $1.25, J.B. weld you should already have.welcome all coments.

definatly get a rechargeable pack, they save you alot of money and even last longer on 1 charge than 4 alkalines would.

Not to rain on a parade, but it depends on what kind you get. A 700mah ni-cad pack just won't last as long. Make sure whatever you buy has a high mah on it for longer run-times.

I'm running 5-cell homade packs that were made out of 2000mah NiMH AA's. They last pretty long on my maxx's.
