Badger did up a custom pack using 2000mah "AA" batteries. Here's the link. Badger's Scorion crawler MODS & PICS (TLT shocks!) |

Here is what I have been PM'ing peeps: "I had a problem with my first pack, so I made another one and gave it to Skippy to test. I don't want to sell these things if poeple are going to have problems with them. I will let you know soon if I am going to make and sell them. If you are in a hurry you might want to check out cheapbatterypacks.com. I just priced a custom built pack with 6 CBP 1650 AA cells in block formation with a deans for $18.00. $21.85 shipped." | |

I've been looking for other AA batteries to test on another truck, and came across this one. GP cells are usually considered the best, and they now have a GP2300 AA battery. I haven't tried them yet. I use Energizer 2500 mAh AAs with very good results.  |

I built a pack from the GP 2300's for my 1/18 bud car and it works great. Well worth the money.

I'd be careful using the Li-Ions. I run a custom 2-cell 2000mah Li-Ion pack in my Mini-T and you have to be careful about the amp draw with them. I'm using LG brand 18650-sized cells and they are only rated at 5A max. I haven't tested the crawler yet to see what the amp load is at stall, but won't even think about putting any of my Li-Ion packs in it until I do. Granted, Li-Ions aren't nearly as dangerous as Li-Polys. But, if the cells get too hot from excessive current draw, the "protection disc" that is at the top of each cell will fail and then there's a chance of the cell going nuclear on you (well...not quite that bad, but bad enough to start a good fire.) |

Where are you getting 3.6V Li-Ion cells for $3 each?! What size are they? Like I mentioned earlier, mine are 18650 cells, which are a bit longer and bigger in diameter than AA-cells. You have to be careful on how hot you get them. If that protection disc ruptures, then the battery is no good (it completely cuts the flow of current both into and out of the cell). Also, make darn sure to not let your voltage drop below 3V for each cell. At <3V, the battery will not accept a standard Li-Ion charge rate and will need to be tricke-charged until the voltage goes back up to or exceeds 3V. You are correct though, Li-Ions are much safer than Lipolys. After seeing a video of a Lipoly pack erupting (literally!), I've decided against using them. I've even heard horror stories about a Lipoly-powered Mini-T getting hit and the battery pack exploding. Scary stuff! |

first off, forgive my lack of knowledge in the subject... anyways, i picked up an Orion Micro RS4 battery pack today. it's 7.2 V, of course, and 1200 mAh. is this going to work? they said it would at the hobby store... also, will the stock charger be up to the task? it just says not to charge it at any more than 1000mAh, and the stock charger is 180 mAh apparently... any help would be appreciated.

changing the connectors is easy... pull the piece off the stock battery and put it on the new battery...
