  • A bit of off topic charging advice

    I know I'm not supposed to raise non heli related subjects but I'm a bit stumped and cant find a definitive answer elsewhere.

    Long story short I'm restoring an old motorcycle and Ive just brought a new 6 volt battery (with acid in it) and I need to charge it up. My car charger only does 12 volts and I'm loathed to go out and buy a 6 volt charger when I've got a bench full very expensive heli charging equipment which will probably do it.

    Any one that know me will tell you that my problem is that I have absolutely zero understanding of electricity and have no idea what settings to put my chargers on, I'm assuming its a "Pb" and should read "6 volts" but what about the A's (amps?) how many of those should I use? And for how long? And what should a volt meter say when its charged?

    Please dont say 20 mins for each 10% to 35% of the overall charge for for 15 kilowat hours per newton megabites (like so many other places advise) cause I dont understand that stuff, it has to be simple for me like set charger to Pb, ?? volts , ?? amps for ?? hours and it'll read ?? when its fully charged.

    Thanks

    3S PB meaning 3 cells in series, Charge at the capacity divided by 5 to be 1/5C. So if it's a 15Ah battery then charge at 3Amps

      In addition to what's posted above.

      Some chargers have safety features such as a 2 hour time limit and a capacity limit of 5000mahs switched on by default. If your charger has those (most 4 button chargers), then you'll need to turn them off as you'll no doubt hit both before the battery is finished charging.
      Current fleet: Goblin Thunder Sport (700), Trex 700L, Logo 600, Specter 700, Henseleit TDR, V-Baaa control.
      Next heli: I have pretty much everything I want. Maybe I'll upgrade some electronics or something.

        MIT says 6N4-2A-5 on it but nothing about Ah's

          If you hadn't of wasted money on a Mcpx you could have got a decent Ctek charger that does both 6 & 12A
