LiPo batteries are pretty cool, so are NiMh. But the problem is: You don't always have to go Hi Tech to perform a simple task. Running a Starter is a simple task and its failure would not cost you hundreds of dollars or hundreds of hours of building time. Such as a battery failure of the receiver or electronic ignition system.<o></o>
So why not keep is simple and keep it inexpensive?<o></o>
<o></o>
Here is an idea: How about any Rechargeable Sealed Battery. <o></o>
Probably one that is in your workshop right now?<o></o>
How about the Battery Pack from your portable electric drill – saw – flashlight.<o></o>
And think about it … You Do Not have to buy a battery charger. And some of the chargers are FANCY <o></o>
With Check lights – Charge lights and Cycle completion lights.<o></o>
Or if one is insistent on spending money – Go to a catalog such as McMaster or Granger and find a <o></o>
Gel Cell that fits the size requirement for your operation.<o></o>
Size being BOTH physical and electrical.<o></o>
Oh, LiPo battery sizes… Or any battery rated in mAH:<o></o>
m = mili - - meaning one thousandth’s of a whole ie: 1000 mA = 1 Amp. 1 mA is 1/1000<sup>th</sup> of an Amp.<o></o>
AH = Amp Hour = How many Amps a battery can deliver for an Hour. Example: a 100 AH battery is rated at 1 Amp for 100 hours or 100 Amps for 1 Hour. NOW! Don’t yell at me… I don’t believe it either, but that is what the AH and rating system says.<o></o>
So, a 2000 mAH LiPo is ONLY – ONLY – a 2 AH battery. The cheapest Tractor Battery or Motorcycle Battery or Drill Battery is WAY OVER 2AH (2000 mAH).<o></o>
Just read the writing on the <st1lace w:st="on">Battery</st1lace>.<o></o>
