7-cell lithium ion battery pack charger, 1.6A at 29.4V, removable 2-prong AC cord, and charge indicator

1800 mA 3 cell 10.8V (12.6V peak) lithium ion charger

2 amp lithium ion battery charger for 5 cell packs

A 7 cell lithium ion pack has a nominal voltage of 25.2V to 25.9V and a maximum charge voltage of 29.4 volts. This is a 1600 mA multi-stage li-ion and li-po recharger with universal AC input. It includes a slow start feature and a 4-segment state-of-charge gauge.

These are state-of-the-art fully isolated battery chargers that can be used on-demand, or left permanently on the battery for maintenance.. It uses energy-saving techniques and and and advanced charge precision. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. Will accurately lithium-ion and lithium-polymer packs.
