Charging Dual Cells without using stock charging terminals?

Hey guys, newbie question here... I'd like to stretch a bit chassis and I was wondering how you guys charge when you dont use the normal charging terminals? they are so much more of a pain, and I thinnk it's be easier to just hook a couple wires up the batts and charge them that way... a good example of my question is CD's pro-stocker. He obviously had no charging terminals... I juss wanna kno how to charge without them!

thanks and sorry for sounding newbie-ish lol

I've stretched a bunch and they all use the normal terminals.
I just make the cut right behind the little side nub grabby deals,
so it still fits on the stock charger. Here's how I've done it...

This chassis is a Thunder Charger chassis
stretched to fit a ZZ body...

That's a pretty sick car you got there hue...does that stretch plate acting like a rear suspension (similar to the Mini-Z's)?

be creative dude. the whirly doo stunt cars have neat plugs for charging. ive borrowed that for one car. usually when i chop a chassis i try to keep the terminals in tact but you could do a lot of different things. be creative. radioshack sells tons of connecters/plugs blah blah or just run wires an inch or two that can be retracted into the chassis somehow or something.

I've looked at that car a buncha' times and never realized how you did that... nice work...

but I was wrong with my explanation. I was thinking more along the lines of a pan chassis with duals and stuff...

this was how I was thinkin of wiring it.

so if I were to just put a few wires from a wall charger, where would I put each? (+) and (-)

hope you understand my stupidity

i personally wouldn't be charging my bits directly from a plug pack, the current (ma) is just too high. you'll need to have a bigarse resistor on the v+ wire if you wanna use one. i'd say a 5w one and between 1 - 10 ohm.

once you've done that to charge you would connect the v+ from the charger to the same place as the v+ to pcb. and the v- from the charger goes to the same place as the ground to pcb.

basically connect + to + and - to - when charging.

Something like this would be helpful. I'm currently trying to score some. I would like to find the smallest ones I can get. I'm about tired of those recharging pads. The recharging base always breaks eventually and the contacts can have problems too.

I'm not sure how big this one is, so I can't really recomend ordering it, although this could point you in a direction. They may have some of these things at the local hobby store. They use them in small scale r/c planes. That's where I'm gonna check next.

If you want constant charge current you can use LM317 voltage regulator and one resistor. It is realy simple and cheap - see diagram
