Ive been hearin a bunch of what-not about charging times and i have a few questions !
1) Do i have to buy a different charger for this mod ?Cant I use my stock charger

2) how does this dual mod compare to the other dual and even triple battery mods (speed wise)

Thanx for the cool mod act of god !

I suggest taking the charging plate off the controller and wiring it to a 3-4 battery holder of your choice. I use 4 AAAs for my ZipZap, works great.

The stock controller charger will not charge a dual or tri cell mod. Check out http://www.questformadness.com/ for some guides to making a custom charger. I wired an AC-to-DC adapter straight to an old charging base. There is a lot of information about regular dual cell mods in this forum; all of that applies equally to this mod.

2) How does this dual mod compare to the other dual and even triple battery mods (speed wise)

The voltage is the same; the weight is less. It may be a little faster. The tradeoff for the easy installation is less capacity though. As with the "standard" extra-cell mods, there is a more noticeable improvement going from one cell to two than from two cells to three.

wow what a great mod , it seemed easy at first and than u hit me witht he hard part charging it do those batteries come precharged cuz i think it would be easier just to buy new ones after every run lol

Actually, mine did come with a little juice in them (kinda unusual.. maybe they did a partial charge to verify the pack was wired correctly?) but it certainly wouldn't be worth buying new ones each time

It's really not very hard to make your own charger. Buy an AC-to-DC adapter rated between 300mA and 800mA, depending on how fast you want to charge (safety vs. speed) and get one rated between 3.0v (for two cells) and 4.5v (for three cells). I got a Radioshack Adapta-Plug so I could change the voltage. I also got a Hobby Leads adapter for it and soldered the two free wires directly to a charging base from an old clone charging pad, leaving the adapta-plug end sticking out a few inches. Now I plug the two ends together and charge away. Otherwise, you could just strip the wires on your adapter and wire it that way.

If you don't have a spare charging base from an old controller or something, I've also done it where I left the charging base in the controller and drilled a hole in the case to run the wire through to the base, then snipped the existing charging wires from the controller. You can connect the adapter directly to the controller then disconnect when the car is done charging. You'll have to time it yourself instead of watching the controller LED, of course.

hey do u think you could put some pics of makin that chrger ? Thanx, i already am hyped about this mod, i ordered two packs of those bats and a 2 AA holder ha then i almost sh!t myself when i found out you need a 4 AA holder !! haa well ill think of sumthing
which brings me to another point what the hell was i thinkign ??
haha cool mod actofgod

im curious can u use all of these batteries and do the same thing http://www.allelectronics.com/cgi-bi...-12&type=store

MadMicroDoc · #39 01-18-2003, 01:22 PM

Im not sure about those batts, looks like they might be a little too big

Just finished the layman's tri and dual mods on a couple of my cars, check it out

MadMicroDoc · #40 01-18-2003, 01:32 PM

another pic

BabyKiller · #41 01-18-2003, 02:09 PM

nice but i would like o know if u can use those batteries cause they have better power 4.8v and 180mAh(i think)

BabyKiller · #42 01-18-2003, 06:04 PM

dang

#43 01-19-2003, 05:04 AM

i hear taht ifu do series then batts wont have more mah
but paralel less volts and more mah
but
rc car batts and cordless phone batts and old cell phone batts
are 3-8 cells and for those they are all in series and the mah adds up and while increasing mah also increasing volts.

how is this done?

BabyKiller · #44 01-19-2003, 02:22 PM

just curious i know it is 40mah but whats the voltage?

Hey BK i think i know what ure talking about. After a few runs with my tri i started experiencing the a hesitating and stalling of my car, it would hall @ss and stop all most instantly. it would also looked like it was "swiching gears or sumthing, looked like it kept hitting the turbo ! But its alrite now, maybe the power wire connecting to he pat that puts electricity to the motor is bent out of shape, take a look.

but who knows
