This means many appliances will operate more efficiently throughout the discharge cycle using LiFePO4 batteries. A lead acid battery decreases in voltage from 13 to below 11.5 volts as more current is drawn. Discharge profile - CMPower LifePO4 Deep cycle Lithium batteries stay at a voltage of 12.5 to 13.4 volts during discharge of up to a 95+%. Lead acid batteries have an expected life of 300-500 charge/discharge cycles at a discharge to 50%. Most CMPower Lithium batteries have a discharge capacity of 150 Amps to robustly accommodate most house, start, windlass, electric winch and inverter battery power requirements.Īdvantages and Features of CMPower LiFePO4 Lithium Marine Batteries Charge/discharge cycles - CMPower Lithium batteries have an expected life of 2,000-4,000 charge/discharge cycles at a discharge to 95%. LiFePO4 batteries are also rated as to their maximum discharge capacity 80 - 100 Amps max discharge capacity is typical. Our most popular CMPower 12V deep cycle Lithium battery is rated at 120 Amp hours and is roughly the size of a group 31 lead acid battery. The BMS will also shut down the system if the battery temperature is out of range. In addition to cell monitoring and management, the BMS will prevent over discharging of cells by disconnecting the load and will prevent cell over charging by reducing charge current or stopping the charge process. The temperature, charge and discharge of each cell is monitored and managed by the BMS, a computer of sorts built into each battery.

Four of these units are connected in series to form a rated 12.8 volt Lithium battery eight for a 25.6 volt battery. LiFePO cells are wired in parallel to form a module producing 3.2 volts. The quality of each component is key to the longevity and performance of the battery. Both are housed in a sealed battery case. A CMPower (Custom Marine Products) deep cycle lithium battery has two primary components, the LiFePO cells and the Battery Management System (BMS). The charge voltage and amperage should be within the range specified for the LiFePO4 batteries. CMPower Lithium batteries are plug compatible with lead acid batteries and will accept a charge from most lead acid configured chargers. The cathode material in LiFePO4 batteries is not hazardous, and thus poses no negative health hazards or environmental hazards. LiFePO4 lithium batteries are the safest type of lithium batteries as they will not overheat, and even if punctured they will not catch fire. Lithium batteries are absolutely ideal for use on cruising sailboats, powerboats, fishing boats, and camper vans.

This battery technology offers many advantages over lead acid and AGM technology including high capacity storage, delivery of consistently high power, longer cycle life, less weight, longer shelf life and rapid efficient charging. LiFePO4 (lithium iron phosphate) is a lithium battery technology that is safe, powerful and plug compatible with most lead acid and AGM battery charging systems.
