Re: Traxxas Series 1 NiMh won't get past 300mAh Happy to hear that you got your pack charged to full capacity. Glad I could be of assistance. Once you've done the slow charging you should be able to use your fast charger at a higher charge with no problems. I also have to agree that you can purchase a couple of lipos for the price of one good NiMH pack. And the power difference is increadable. I have two vehicles with the Velineon Power system and going to Lipo was an awesome move up. Don't forget to set your ESC for "Low Voltage Detection" if using Lipos, (not necessary for running NiMH packs!) All the best with your vehicle and your batteries my friend. |

Re: Traxxas Series 1 NiMh won't get past 300mAh You can charge both @ once.... Don't waste money on another nimh pack.... For the price of 1 nimh pack you can buy lipo and charger.... www.hobbypartz.com... A US website.... 5a lipo/life/nimh/nicd charger ...23$ 1800 mah 5c charge/30c discharge lipo 13.60.... Shipping .... Flat rate 9.99 to canada.... To your door 4-5 days.... Under 60$ for 2 lipo and a charger shipped to your door. |

Re: Traxxas Series 1 NiMh won't get past 300mAh You guys are good! I charged it up at 0.5a, and although it took a while, it reached 1200mAh with no problems whatsoever. I can charge it up at 1C now with no problems at all. Now, just one more (probably stupid) question while this thread is still going. Is it possible to charge two 6 cell Ni-MH at the same time using my Traxxas y-parallel adapter with a DuraTrax peak charger? I've read a few things about this, and am still unsure about it. I really don't feel like buying another Piranha since I might make the leap to LiPo soon (Maxamps has a great start-up kit for the 1/16 Revo). But, if I were to keep my nickel metals around, I'd probably invest in an Onyx 240 to charge two packs at once. |

Re: Traxxas Series 1 NiMh won't get past 300mAh Thank you for your input my friend. I had no idea that Traxxas tested their battery packs at the factory before sending them out, so yes, in this instance you are right, no need to do the forming charge as it has already been done. But for most other packs one would purchase, I don't think that they would be already "Formed" before being sold. I'm an airplane guy and up until just reciently I had never owned a land vehicle. I always purchased Nicad and NiMH cells by the box of 50 cells and assembled my own packs. In this application I did find it necessary to use a slow forming charge for the very first charge of a pack. Still, even with car packs, if in doubt, it is always good policy to do likewise with these packs. Fast charging a new NiMH pack (anything over 1C that has NOT already been factory charged) could actually damage a pack so that it will never be able to accept a full specs charge. Forming assures that this doesn't happen and results in a relyable pack that has a long serviceable life. As for the beer pouring parable, I was just trying to use a visible analegy that one could easily relate to so that the point I was trying to make could be more easily understood. It was not meant to be scientifically critical! For those who would like some very good discussion on the various types of battery cells, Ie: Ni-Cad, Ni-MH, Li-Poly etc, and how best to charge, cycle, & store batteries, check out "Red's Battery Clinic" on line. Red Scholefield is one of the foremost battery experts in all of North America, whom I had the great priviledge of meeting a few years ago at the Weak Signals RC Expo in Toledo Ohio, where he was giving a battery seminar. A very nice gentleman who has a wealth of information that he gladly shares. Do check out his website! You won't be disappointed! |

Re: Traxxas Series 1 NiMh won't get past 300mAh and batteries are cycle tested in the factory . . . . . brought up to full charge and drained to half or less capacity . . . you dont even have the oportunity to be the first one to charge it . . . . im sure that those cells are charged 2 times before you get them . . . . once @ the chineese factory there built in . . then one more time @ traxxas so they feel comfortable warranty the pack . . . . . I feel your theory is wrong . . . . when you fill an empty beer glass the resistance of the dry glass produces that head . . . . .a wet glass produces less head than a dry glass . . . hence why they put it on that sprayer before they fill it . . . .so all traxxas packs been charged 2 times before you get it . .. . maybe your theory would hold up if they were brand new . . . but . . they all been charged 2 times . . . . now new . . traxxas and MADEINCHINABATTERYFACTORY already did the hard work for you . . .. CALL TRAXXAS . . . . THEY WARRANTY THESE PACKS . . . YOU HAVE AN ISSUE . . .. COLLECT YOR NEW PACK . . .. . |

Re: Traxxas Series 1 NiMh won't get past 300mAh Quote:
I like to use the analigy of pouring a glass of beer. Pour it too fast and it fills up fast but when the foam settles down, there is only a half glass of beer. Pour it nice and slow and you nicely fill the glass. Same with doing the initial charge on a Ni-Cad or Ni-MH battery pack, charge too fast and you will get a false peak leaving only about half a charge or less. Give it a nice slow charge the first time and it will be at or exceed specs and you will have a nicely formed pack that will last you a long time without trouble. Once the battery has been charged this way for the first charge, you can charge as you normally would and should have no problem getting a full charge from thereon. IF you still have a problem even after this, I would think, as has been said, there is a problem with the pack, which is rather unusual for a Traxxas Series pack. I have only been with RC cars for a short time but have indeed found the Traxxas service to be very good. I'm sure they will replace it for you. |

Re: Traxxas Series 1 NiMh won't get past 300mAh Probably a good idea. I hear their customer service is actually pretty decent. I just drained it again, and I'll try charging it at around 0.5A. Maybe I charged it too fast for the first charge, and I'll try a slow charge. If not, it's to customer service I go! |

Traxxas Series 1 NiMh won't get past 300mAh I just had a quick question I was wondering if someone could help me with. I've been a nitro guy my whole life, so anything electric is pretty new to me. My AE GT2 got smashed up pretty bad last week, so while I'm waiting for parts, I decided to buy a 1/16 E-Revo. Anyways, I decided to buy two extra packs (2 Dynamite 1600mAh 6 cell packs), but it also came with the one Traxxas Series 1 pack, which after some research is 1200mAh, apparently. Both times I've charged this one pack, I can't get it get past 300mAh charge. I'm charging at 1.2A using a Duratrax Piranha digital peak charger, so I'm not sure why this is happening. Like I said, everything related to batteries is new to me. I charged the Dynamite batteries, and it gets right to around 1550mAh no problem with the same charge settings. Thanks for any help! |
