LiFePO4 Lithium Camper Van Batteries - Product Summary
Specifications for 12-24V 100-150A Continuous Draw (read starter) CMPower LiFePO4 Lithium Batteries
LiFePO4 Battery Showing Cells and BMS Electronics
LiFePO4 (lithium iron phosphate) is a lithium-ion battery technology that is safe, powerful and plug compatible with most lead acid battery charging systems. 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 batteries are the safest type of lithium batteries as they will not overheat, and even if punctured they will not catch fire. The cathode material in LiFePO4 batteries is not hazardous, and thus poses no negative health hazards or environmental hazards. CMPower LiFePO4 batteries are plug compatible with lead acid batteries and will accept a charge from most lead acid configured chargers. The charge voltage and amperage should be within the range specified for the LiFePO4 batteries.
A CMPower (Custom Marine Products) LiFePO4 lithium battery has two primary components, the LiFePO cells and the Battery Management System (BMS). Both are housed in a sealed battery case. The quality of each component is key to the longevity and performance of the battery. LiFePO cells are wired in parallel to form a module producing 3.2 volts. Four of these units are connected in series to form a rated 12.8 volt LiFePO4 battery; eight for a 25.6 volt battery. The temperature, charge and discharge of each cell is monitored and managed by the BMS, a computer of sorts built into each battery. 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 BMS will also shut down the system if the battery temperature is out of range.

Advantages and Features of CMPower LiFePO4 Lithium Marine Batteries
Charge/discharge cycles - CMPower LifePO4 batteries have an expected life of 2,000-4,000 charge/discharge cycles at a discharge to 90%. Lead acid batteries have an expected life of 300-500 charge/discharge cycles at a discharge to 50%.
Discharge profile - CMPower LifePO4 lithium camper van batteries stay at a voltage of 13 to 13.4 volts during discharge of up to a 95+%. Voltage then drops off rapidly. A lead acid battery decreases in voltage from 13 to below 11.5 volts as more current is drawn. This means many appliances will operate more efficiently throughout the discharge cycle using LiFePO4 lithium batteries.
Discharge rate - The BMS built into CMPower camper van batteries has a 100 amp or a 150 amp discharge capacity. This means the batteries can sustain a heavy charge and discharge without damage or degradation. Our manufacturer has advised us that the quality of the cells and quality of the BMS is key to the longevity and performance of a LiFePo4 battery. We have seen this firsthand.
Charge/discharge cycles - CMPower LifePO4 batteries have an expected life of 2,000-4,000 charge/discharge cycles at a discharge to 90%. Lead acid batteries have an expected life of 300-500 charge/discharge cycles at a discharge to 50%.

Weight/power ratio - A typical 100 Ah LiFePO4 lithium camper battery weighs about 31 pounds. A comparable lead acid battery is over twice that. Because LiFePO4 batteries can be safely be drawn down 95% vs 50%-60% for lead acid, fewer batteries are required to achieve the same power. Battery weight combined with usable power capacity means battery bank weight can be cut by more than half using LiFePO4 lithium batteries. Also, LiFePo4 batteries will occupy up to 40% less space than equivalent lead acid batteries. They are ideal for powering trolling motors.
For example, 3 group 31 110 amp hour lead acid batteries weighing a total of 200 pounds can be replaced by 2 group 31 size 100 amp hour LiFePO4 batteries weighing a total of 62 pounds. Both configurations have roughly the same power capacity because the lead acid can be safely drawn down 50% (330 amps @50% = 165 amps) and the Lithium battery can be safely drawn down 95% (200 amps @ 95% = 190 amps). Also, the lead acid will endure 300-500 cycles and the LiFePO4 over 2,000 cycles.

Smartphone app for LiFePO4 Battery Monitoring
Safety - Lithium batteries have a reputation for catching fire. This is not so with LiFePO4, a very different technology. The built-in Battery Management System (BMS) monitors the state of charge of each cell group and manages the temperature, charge and discharge rates. The BMS will prevent over-charging and over-discharging by disconnecting from the source. There are no toxic chemicals or gases as in many types of lead acid batteries. The batteries can be mounted in any direction; bottom or side. No worries about having them in your living area, no toxic chemicals and much lower fire risk than lithium ion batteries.
Compatibility - While the optimal charging parameters vary between LiFePO4, AGM and lead acid battery technology, the BMS built into CMPower LiFePO4 camper batteries compensates for this. Thus, our LiFePO4 camper van batteries are compatible with most lead acid battery charging systems.
Bluetooth Battery Monitoring - CMPower LiFePO4 batteries are equipped with Bluetooth for monitoring battery State of Charge (SOC) through a Smartphone or tablet app. This is important because unlike lead acid batteries, LiFePO4 batteries maintain a constant voltage between 13 and 13.4 volts so a voltmeter is not an accurate indicator of SOC. A built in Bluetooth capability enables real time monitoring of each battery through an app on either an Android or IOS smartphone or tablet. The app displays the state of charge (SOC) of the battery, the amp draw and voltage level, the temperature, the time to full charge and the number of charge/discharge cycles. This capability is nearly equivalent to having a built in battery bank monitoring system like a Link 2000.
Winter Operation and Storage - CMPower LiFePO4 lithium camper van batteries can be stored in temperatures from -10°F to +104°F (-25°C to +40°C). It is recommended they not be heavily charged and discharged at temperatures below -4°F (-20°C) . It is recommended that the negative terminals be disconnected during winter or long term storage so there is no chance of draining the batteries while in storage. LiFePO4 batteries should be recharged at a minimum every 6 months while in storage.
Long Term Investment - Keep Them for Life - Because the number of charge cycles of well cared for CMPower Lithium batteries is in excess of 2,000 they can be a long term investment you can take with you from van to van or van to boat or van to RV. Also, because the batteries have a built in cycle recording system, the batteries can be resold at a value based on their number of charge cycles. For example: The owner of a sailboat purchased three CMPower Lithium batteries two years ago; two for house and one for engine starting. After two years of cruising the starting battery had 2 charge cycles and the house batteries, wired in parallel, had only 20 charge cycles as shown on the Bluetooth APP. These batteries are like new and can be taken to their new boat or sold as quality longlife used batteries. In fact, if and when CMP LiFePO4 camper van batteries become available from our customers, we post them on our website for purchase.
Cost - CMPower LiFePO4 batteries are 2 to 4 times the cost of comparable lead acid or AGM type batteries. Cost justification is often based on convenience, performance and longevity. Factors to consider in evaluating cost include the number of charge cycles, power to weight ratio, charge and discharge efficiency and compatibility. Over the long term, these batteries are often considerably more cost effective than lead acid or AGM batteries for van applications.
Bottom line - CMPower LiFePO4 camper van batteries have the following advantages:
1. lighter than lead acid - generally less than half the weight of lead acid
2. can be drawn down 90% vs 50% - more useable capacity
3. hold steady voltage through 95% discharge - constant power and voltage
4. generally plug compatible with lead acid chargers - drop-in replacement
5. charge more quickly and efficiently than lead acid batteries - excellent for solar systems
6. have up to 10 times more charge cycles than lead acid and AGM batteries - could last a lifetime

8. low self-discharge - easy winter storage, long shelf life
9. Bluetooth equipped to monitor battery State of Charge with free app - built in battery monitor
10. cost effective in the long run
They are more expensive than lead acid however their advantages and longevity often outweigh the additional initial investment.

What are the advantages of lithium batteries over AGM or lead acid batteries?
LiFePO4 lithium batteries are safe, powerful and plug compatible with most lead acid and AGM battery charging systems. LiFPO4 battery technology offers many advantages over lead acid and AGM technology including high capacity storage, consistently high power at same voltage (meaning higher operating efficiency), much longer cycle life (up to 10x), less weight (half), longer shelf life and rapid efficient charging (20% more efficient), availablity of 95% of rated battery amperage instead of 50-60% available amperage.
What is in a LiFePO4 battery?
A LiFePO4 battery has two primary components, the LiFePO (lithium iron phosphate) cells and the Battery Management System (BMS). Both are inside a sealed battery case. The quality of the cells and BMS are key to the longevity and performance of the battery. LiFePO cells are wired in parallel to form a single module producing 3.2 volts. Four of these modules are connected in series to form a rated 12.8 volt LiFePO4 battery; eight for a 25.6 (24) volt battery. The temperature, charge and discharge of each cell is monitored and actively managed by the BMS, a computer built into each battery. 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 BMS will also shut down the system if the battery temperature is out of range and wait for it to come down before continuing to charge.
