[NSRCA-discussion] How do I power my TP 1010C charger?

Tue Apr 28 10:48:57 AKDT 2009

Anthony,

If you go the Iota route take a look at the charge box made from a Harbor Freight tool box at the bottom

of Chris' page here:http://www.electric-f3a.com/

Click on the picture and there's a neat sequence of step by step photos on how to build it.  It really organizes the 

clutter and jumble of stuff you have otherwise.  I'm building one and it's great!

Anthony:
  The key is to reset the low voltage cutoff threshold in the 1010 charger to 10V.  It is factory set to higher to prevent you from killing your car battery and not be able to start your car and get home.  If you have a separate battery then it does not matter how low you get it.  That said, a deep cycle is better suited for us than a car battery unless you already have a spare car battery.  My DieHard deep cycle is 3 years old and I get 5+ full charges into a 10S pack from it at the field at 5 amps charge rate.  The Iota is worth every penny if there is a/c power available (and a lot lighter).

Ok here is another "E" question for you guys.
I set up my Thunder Power 1010C charger and 210V balancer to charge a set of True RC 5000 batteries wired as one 10S pack. I set the charge rate at 1C so it would charge at 5 amps. I had the charger powered by a pretty strong car battery that was fresh off a two day trickle charge. Everything started fine and it charged for about a minute then I got an input power error message. I placed a call to the only electric expert I know and was advised to lower the charge rate. I set it at 2.5 amps and it charged for about 45 minutes at that rate then I got the same message. I reset it at 2 amps and it completed the charge cycle.

Questions:
1. Can I run that charger off of a car battery or do I need what I have heard referred to as a deep cycle marine battery? I used it because I had it handy and figured I would at least try it.

2. Just out of curiosity, what is it about the car battery that makes it unsuitable for powering that charger? Is it a lack of sustainable amperage, voltage, etc?

3. What are my options for powering that charger? I am open to getting a generator but would like to consider all the options. More than likely I will always arrive at the practice field with 3 or 4 fully charged packs but will definitely need to recharge during a contest. I can't run the charger directly from the generator, what else would I need to buy? I am looking for reliability, portability, and a good value (not necessarily cheap). I can lug a battery to the field just as easily as a generator and have a good battery charger. 

What have you guys used that has worked well (Marine batteries, generators, power supplies/converters). I do not want to reinvent the wheel so I am interested in what has worked in the past.

Thanks
Anthony
