Progressive Dynamics recently developed several models of 12 and 24-volt power centers for RVs, designed to meet the requirements of Lithium Ion Phosphate Batteries and providing the Constant Current Constant Voltage charge profile required by lithium battery manufacturers. Standard features of Progressive Dynamics’ lithium ion battery power centers include reverse battery protection, electronic current limiting, low-line and high-voltage protection, and a variable speed 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.
Progressive Dynamics also provides Lithium Battery Power Center units for RV owners, dealers and manufacturers to update their current system to a Lithium Ion Battery System.
A lithium, 100-amp-hour battery can be fully recharged in 2-and-a-half hours compared to 6 to 12 hours for lead/acid batteries. It can also provide a longer battery life, with a recharge cycle up to 5,000 times, compared to 300 to 400 cycles for lead/acid batteries. Lithium ion batteries do not have to be charged during storage. Lithium ion batteries deliver up to threetimes the energy of a lead/acid battery within the same space and at approximately half the weight.
