Progressive Dynamics Inc. continues to develop 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. 

According to a press release, standard features of the company’s lithium ion battery power centers 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.

Progressive Dynamics also provides lithium battery power center units for RV owners, dealers and manufacturers to easily update their current system to a lithium ion battery system. Advantages include no battery maintenance and faster recharge from both the power centers and solar charging systems.  A lithium 100AH battery can be fully recharged in 2 1/2 hours compared to 6-12 hours for lead/acid batteries.

They also provide a longer battery life, with a recharge cycle up to 5,000 times, compared to 300-400 cycles for lead/acid batteries and lithium ion batteries do not have to be charged during storage. In addition, lithium ion batteries deliver up to three times the energy of a lead/acid battery within the same space and at approximately half the weight.
