I saw your post and say they were over 200 bucks each. The battery would expire but I broke even from using it. I wanted to go on the cheap side and was trying to size it.
I see a small lifepo4 motorcycle cell on ebay for 49.95. It states its not a starting battery, but for those with a kick starter. Its rated at 12 volts and a few amps.
