NMP 7.4v 2Amp Battery Packs

[Wayne Galligan]

Jim,

Is that the "Miracle Switch" w/6v regulator that your talking about from Maxx?

  Way to go Troy.  
  For Dieter: The Maxx Products regulator I reviewed was a switching regulator.  These work by switching the applied dc voltage on and off with a variable duty cycle that self adjusts to hold the output voltage constant.  The switching is basically a high frequency square wave that creates many harmonics that potentially can cause radio interference.  Mike's obviously works but I know others have had trouble.  Powerflite sold this same regulator initially but has since gone to a linear regulator.  Maxx may have changed also but I don't know.  If you get one, check your ground range with and without the regulator to make sure you are not getting significant loss of range.

    Jaccio regs made by Jim Oddino are the only regs I trust.

    Central has them.

      Thanks for all the info. My next question was going to be what voltage regulator are you guys using as I haven't selected one yet. Now that you have recommended the Maxx Product I'll probably go with that. 
      Thanks again.

        Dieter I use a similar pack (Berns) in my Tempatation with about the same servo's and it's better than good. As far as the charger goes I tend to stik to the deticated charger lik the NMP but I have used my Triton on it and it works fine. I think you will be pleased with the system. What regulator are you using on the system. I have found the Maxx Prod. 10Amp to be very good. Mike

        I just purchase these battery packs and according to the included
        instructions is mentions to "Only use NMP's Lithium charger to charge
        these packs." I was wondering if anyone might know why this would be
        the case. Shouldn't any Li battery charger work? I already have a
        Kokam Li battery charger which allows me to charge at various rates.
        Is there a legitimate reason why I should buy their charger or should
        any Li charger work? Also, I was surprised at the diminutive size of
        the pack. Does this pack have enough juice to power 3x JR9411, 1x3412
        and 1x8411 in a Temptation? At 2A I would assume that this would be
        more than plenty? I would be interested in hearing anyone's experience
        with these packs.

        Thanks

        DIeter
