I finally found a reasonable Lithium Battery by Valence. It's a rechargeable Lithium Iron Magnesium Phosphate 40 amp hour Battery from a medical cart. It weighs 15 lbs. First impression is very good, It started out stronger than my 60ah (40lb)AGM car battery and came on stronger after a 3 minute rest. It tested 13.34volts before and 12.92 after my 3 mile round trip. Total cost with shipping was $128. eBay US. It has pos/neg bolts and complicated cables I'm ignoring at present. There is a flashing green led on top and it has built in circuitry that shuts down the battery at 10 volts to avoid damage. I'm thinking of buying a second one to wire in series. I need to read more on charging but, the seller promised me I could use a normal car charger. I've read that Lithium 40ah is underrated and more like a 60-70ah but, this remains to be proven. http://s1066.photobucket.com/albums/u406/ftpstuff/?action=view¤t=50e97a8db2039a7f6c8683d6121f4863.jpg" target="_blank"
