PowerStream now offers this chargers for 18 volt Pb-acid batteries specifically designed for the personal electric vehicle market. These are have several advantages over the OEM Mini-moto style chargers, including the following attributes:


OEM Battery Chargers 18VDC Multi-stage "smart charge" algorithm is kind to the battery.

OEM Battery Chargers Switchmode based instead of transformer based make the chargers smaller and lighter as well as being much more energy efficient.

OEM Power Supplies Universal Power Input means that the 18V chargers can be used in any country using anything between 90VAC and 264 VAC.

OEM Power Supplies Replaces the mini-moto part number ZED57054U with a higher power charger that is much kinder to the battery.
