I used LiPo batteries for my RC planes. Very reasonable pricing. Cant beat the power /weight or power/volume. Cheapest battery size is 3 series 2200mAH packs, 12.6V fully charged. On a sale such a pack is ~ $10? and up for a 20C discharged rated pack. Series connect 2 packs and parallel up for more capacity. One store I often order from has a sale.
prices and shipping charges vary by region. As others have mentioned charging and discharging is important to follow the LiPo chemistry requirements.
I thought of using LiPo but I friend gave me some UPS maintenance pulls, so I am using NimH's at this time.?
