The Layman's Dual Cell Mod (tm)

[bdebde]

HEY! I like this dual and triple cell mod. The run time would be pretty decent if peak charging. Although the motor you use and how you drive will determine run times (notice Tiny used 1.0 motor for his test). A faster motor will eat the juice faster. I have a dual 150 mah Zip Zap with clone pcb, NOS motor and I rarely charge it to full capacity or run it dead just because I don't have enough time to run it forever. I use a high end peak charger from my 1/10th scale RC cars to charge (I been watching Peak Char-g'd thread). I also have a couple of booster cars, which seem to eat the juice a little faster too. Even the stock 50 mah battery provides excellent runtime of 20 to 30 minutes depending on motor used. I guess I will try your battery mod in a booster to see how it works with peak charging. I also like the no solder/ no destroy for this mod. I was going to take a pcb from a booster and put it in a Zip Zap because it is easier to fit two 1/3aaa batteries in the chassis, but now I may hold off on destroying a booster car. Although I do like the longer wheelbase on the Zip Zaps, which handle real well at the high speed of dual cells (hmm, may try this mod on a Zip Zap too). Higher charge currents will kill a battery quicker. I been running 300 to 500 ma charge rate, just depends how long you want to wait for the battery to charge.
