|  charger mod help !!!
hey guys i have a losi micro rock crawler, now the battery charger it comes with puts out 12v 500mah for a 4.8v 180mah micro t battery. i have a spare mini-t wall charger(non peak) and i wanna put the curcuit bourd from the charger onto the wall charger output wires, effectivly saving a butt load of money on batteries and replacing it with a peak wall charger for the micro battery. the wall charger is 9v 500mah... will it be possible to get this to work or is 9v too low of a voltage compared to the stock battery chargers 12v (8 x AA) keep in mind the mah are exactly the same. any help is greatly appreciated. |

Ummm....can it work? Likely, with some mods to a lot of the boards. If you understand circuits, you can do it. Better would be to build your own peak charger, if you knew how. Best bet is to spend a bit (maybe split the cost with a friend) and get a decent charger. The mah is not what determines the peak charger, it's the voltage it is designed to reach. The finish voltage for a 1S 500mah pack is MUCH different than the finish voltage for a 4S 500mah pack. Actually, it's 4 times the voltage.......  |

Do yourself a huge favor and get a proper charger, it's well worth the investment and they can be had for relatively cheap. For example the Accucel 6 from hobbyking is only 22.99 USD + shipping: http://www.hobbyking.com/hobbyking/s...idProduct=7028 You will need a power supply though but if you put in a little work you can convert a PC power supply for suitable use. However since are only charging 180mah batteries right now you could get away with a wallwort style that can put out 12V @ around 2amps. If you choose to order from hobbyking grab some lipo's as well and ditch those NiMH packs. |

I cut up the stock charger and fit it into the radio base where the batts normally go.Tap a line to feed the radio with just the 4 cells it needs for power and run your charge line plug external.I even cut a hole and added the little light to show charge status in the radio base. Now I can charge thru my radio and not need to carry all the extra junk.
