A battery single charger may accommodate Li-type and Ni-type batteries, having default charge settings and user-adjustable charge parameters in an ‘advanced mode’. Lithium Polymer (LiPo) batteries equipped with RFID technology and integrated balance taps may communicate with a device such as a battery charger equipped with similar technology providing information such as chemistry type, cell count, recommended charge rates, number of charges on the battery, among other types of information. Several safety features may be included.
