Best battery?

Hi guys this is my first time on yourmicro.com , ha used to be at one18th.
Anyways i just bought a micro rs4 and am really fed up with the charge and run time of the stock battery. I have a mini-t with a brushless and lipo system so im not new to the rc world, i just want to know what i should get to get longer run times and faster charging while its still stock.


I remember a long time ago in car action there was a article about the hpi workers and their micro rs4 and how they created a 6cell pack out of the energizer 2500mah rechargeable batteries that would last for like an hour or hour and a half?? is this right.

Thank you

The latest AA rechargable batteries I can find are from Staples and are 2650mah. You could make your own 6-cell pack from some of these no problem. I have also used some 2/3AA 650mah NiMH cells from CheapBatteryPacks.com which are small and light. The 2/3A Intellect 1500mah cells are also great and have double the capacity too.

The Duratrax AC/DC Digital Piranha charger is fine for Nicad and NiMH micro packs. It will charge up to 3 amps when using DC power and up to 5 amps off a 12V power supply.

Building your own packs is really quite easy. I use the de-solder braid as sold at Radio Shack to connect the cells and it works great. I use Goop / Shoe Goo to adhere the cells to each other and let that dry overnight. You don't need too much so use sparingly. Next day I tin the ends of the cells and then add the braid. Lastly, install your connector and you're done.

5 or six cells?

so as i was reading other things and began adding up voltages i realized that 6 cells equals 9 volts. and i thought the stock electronics or car was supposed to run at 7.4 volts or so? is this right? so would i need to get only 5 cells ? if they are 1.5 volts each? or is my choice of the 2500 mah batteries from energizer or whoever kind of dumb and should i just get actual r/c car batteries from cheap battery packs or something that run 1.2 volts each ??? thanks

Nicad and NiMH rechargeables are only 1.2V each and you are safe with a 6-cell pack.

2/3a batteries?

whats the difference in a 2/3a and like a AA battery is it just size? im kind of confused looking at cheapbatterypacks and seeing like 4000mah batteries? so if size is the only difference would like a 3000 to 4000 mah battery be better? and also seeing as how this is all pretty confusing whats the best battery pack i can buy for the longest run times to fit directly into a stock micro rs4? li-po?

Batteries come in different sizes as well as MaH ratings so you need to look at both. AA cells are thinner than A cells, and a 2/3A cell is shorter than an A cell. The Cheapbatterypacks.com web pages show the cell measurements as well.

You can always go with a 6 cell pack and the stock motor, it should give you plenty of runtime to fit your needs........and if you want even longer runtimes just pop in another pack when the first is depleted.

just get any hobby grade 2/3A battery packs! When I mean hobby grade, I mean known in the RC world and you should be pretty good.
