The 60 amp Progressive Dynamics INTELI-POWER 9160AL converter charger is designed to meet the stringent voltages required for properly charging and maintaining lithium batteries.

Lithium batteries, like LiFePo lithium lead phosphate RV batteries, require special balancing circuits and chargers!

12-Volt Lithium 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. Lithium Iron Phosphate type cells are the safest and most common type used,
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.

Due to manufacturing inconsistencies, each Lithium cell is different (i.e. they will each charge and discharge at different rates). These cell differences 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. While these balancing circuits protect the cells, they can increase recharge times, depending on the mix of cells in each 12-volt battery pack. This increase in recharge time is especially apparent in higher voltage and or higher current battery packs.

Lithium batteries also require battery chargers that can produce a higher voltage than provided by standard 12-volt or 24-volt lead/acid battery chargers. Trying to recharge a Lithium battery with a standard lead/acid charger will result in a partially charged battery and MAY REDUCE BATTERY LIFE.

The 9160AL Features:

• Reverse battery protection protects converters from damage resulting from improper (reverse) battery lead connection.
• Units deliver filtered DC power to the Lithium batteries to ensure their built-in electronic balancing circuits operate properly.
• Electronic current limiting automatically reduces output voltage when maximum capacity is exceeded. Protects your investment.
• Variable speed intelligent cooling fan automatically monitors converter temperature and activates fan at speed required.
• High voltage protection protects converter from spikes or surge of voltage over 135V.
• Automatic thermal protection reduces converter output to safe levels when unit temperature exceeds pre-set limits and protects converter from damage due to excessive heat.
• The PD9100AL Series can be wired in parallel to charge at much higher current rates. They can also be wired in series/parallel to charge 36, 48,60, 72 and higher voltage battery packs at high charge rates.
• 2 year limited warranty.
