A lithium-ion battery converter/charger, the Inteli-Power 9100L series, is available from Progressive Dynamics, Inc. These 12 volt and 24 volt lithium-ion battery converter/chargers are designed to meet the stringent voltages required for properly charging and maintaining lithium batteries. Lithium-ion batteries require special balancing circuits and chargers to prevent overcharging a cell or discharging too much.
Standard features of the Inteli-Power 9100L series converter/chargers include reverse battery protection, electronic current limiting, low line and high voltage protection and a variable speed intelligent cooling fan. Units also deliver filtered DC power to the lithium-ion battery to ensure the built-in electronic balancing circuits operate properly. Output voltage can be factory adjusted to meet OEM requirements for various lithium-ion battery chemistries and voltages.
These converter/chargers are designed for lithium-ion batteries, that typically store three to four times the energy of a lead/acid battery within the same space, with less weight.
