While these balancing circuits protect the cells, they can increase recharge times, depending on the mix of cells in each 12-volt battery pack. These cellĭifferences make recharging Lithium Batteries fairly complex and requires that the battery manufacturer install electronic balancing circuits inside the battery to prevent overcharging a cell, or discharging too much. they will each charge and discharge at different rates). However, they must never be charged to a voltage over 4-Volts and must never be discharged below 2-volts, or they will be damaged.ĭue to manufacturing inconsistencies, each Lithium Ion Cell is different (i.e. Lithium Iron Phosphate type cells are the safest and most common type used, Lithium Ion Batteries require special balancing circuits and chargers!ġ2-Volt Lithium Ion Batteries are composed of 4 cells, each with a voltage rating of 3.2-volts wired in series providing a total output of 12.8 Volts. They can also be wired in series/parallel to charge 36, 48,60, 72 and higher voltage battery packs at high charge rates. The PD9100L Series can be wired in parallel to charge at much higher current rates.Series voltages are set for 14.6/28.55 volts to meet requirements for Output Voltage can be FACTORY ADJUSTED to meet OEM requirements for various Lithium Ion Battery chemistries and voltages.Automatic thermal protection reduces converter output to safe levels when unit temperature exceeds pre-set limits and protects converter.High voltage protection protects converter from spikes or surge of voltage over 135V.Temperature and activates fan at speed required. Variable speed intelligent cooling fan automatically monitors converter.Low line voltage protection automatically shuts converter down if input voltage is insufficient.Electronic current limiting automatically reduces output voltage when. Their built-in electronic balancing circuits operate properly. Units deliver filtered DC power to the Lithium Ion Batteries to ensure.Reverse battery protection protects converters from damage resultingįrom improper (reverse) battery lead connection.
