I am sick of using lithium polymer batteries lately. After using a battery for one month, it discharges faster then before. Also, while recharging it, I need to stay close to it for safety reasons (overheat, overcharge, explosions: as recommended on many blogs). And finally, each time the voltage on one of the cells drops below a certain threshold, I throw away the battery (NimH charging is damaging the batteries).
Do you have any suggestion other than LiPo batteries? If no, what should I do to prevent all of these issues?
