People sometimes ask why one would want to go with A123 batteries for radio-controlled aircraft, rather than Lithium-ion Polymer batteries. A123 batteries are heavier, lower voltage, and lower capacity than comparable LiPo batteries. Well, in addition to their tremendous cycle life (more than 1000 recharges, compared to roughly 300-500 for a LiPo), faster recharge times, and slightly lower cost, there’s this reason.
