    Battery questions for Dummies™

    So, before I forget to mention this. I should add that these questions pertain more to the EZ starter for Nitro and not really batteries for racing per say.

    So, I bought a battery charger about 14 years ago. It's a 1 amp trickle charge at 35-75mA and a 5 amp fast charge. Because of its age, it was meant to charge NiCd batteries. So, is it still possible to use it to charge LiPo batteries too or am I going to need a more modern charger to charge a newer battery?

    I realize that because this is only for starting a truck and not racing, I'm not going to need the top of the line battery. However, I am curious about the battery capacity rating. If I get a 3600mah battery vs. a 1800mah battery, will it only carry a longer charge for more starts or will I get better peak performance too? The battery I have now is 14 y/o too so its ability to put out has diminished. So, I have to put a glow plug warmer on to use the EZ starter to turn over the motor; it is too much of a stain on it to try to do both right now. I also realize that battery technology has improved over the years as well so they have a much better plateau before losing output now. While I am sure a 1800 is all I really need but would I get a longer battery life and better starting with a 3600?

    Please and thank you for all of your answers.

    The Lipo would blow up on that charger, I would get the Traxxas 6amp peak plus.

    If the battery you are looking at has the balance plugs, you could get the cheap cheap traxxas charger

    Is there any special reason you want a lipo to power an EZstart as far as i know there is no reason for a lipo for that application you could buy an inexpensive nimh for that and it would be percectly fine.
    If i am wrong please let me know.
    Also if you use a lip wouldn't you have to discharge it to storage voltage after each days use?

    New to this whole idea of RC and getting into it to spend time with the kids without a TV involved! Just bought to 7.4 7600 2 cells and an Ez Peak Plus. When I set it up to charge 6 amp and 7.4 volts I immediately get "Battery Check Over Voltage". Since the instruction manual isn't worth the paper its written on...could anyone give me a hint as to what I'm doing wrong?
