NOTE: Enduro Power batteries are designed for DEEP CYCLE applications. Our advanced lithium iron phosphate (LiFePO4) technology excels at storing energy and enduring long demands for power. They are not designed to be used as starter batteries for vehicles or other similar uses.
If you have one battery in your system charge it prior to initial use. When building a battery bank connected in parallel or series it is important to charge each battery by itself prior to connecting them to ensure proper balancing. Charge each battery to within 0.1V of each other prior to connecting in parallel or series to minimize imbalances between batteries within the bank
When charging Enduro Power batteries you can use many different charging sources (converters, chargers, inverter/charger or solar charge controllers). For standalone chargers/converters look for a unit that has a LiFePO4 charging profile that matches your battery bank voltage (bulk voltage range listed below). Here are the most common settings required to setup systems with inverter/chargers or charge controllers.
All Enduro Power batteries feature low temperature charging protection. Enduro Power protects your lithium investment by ensuring no damage is done to your batteries in cold temperatures. Charging below 32F LiFePO4 chemistry can begin irreversible damage reducing capacity and cycle life. Enduro Power lithium batteries provide you peace-of-mind knowing you won’t be able to accidentally damage your batteries while charging from any power source (shore power, generator, solar charge controller, battery charger, etc). Our advanced BMS will monitor the temperature and only allow charging when the temperature of the battery is above 32F. We have you covered, the operating temperature for discharging Enduro Power batteries ranges from -4F to 130F so you will always be able to draw power (discharge) out of your batteries anytime to run your favorite gear/appliances while things warm up!
|-4F to 130F (-5 to 55C)
|32F to 130F (0 to 55C)
To maximum performance LiFePO4 batteries are best stored between 30-80% state of charge (SOC).
Short Term Storage
|-10F to 130F (-5 to 55C)
Long Term Storage
|23F to 95F (0 to 55C)
Enduro Power batteries feature a high-performance battery monitoring system (BMS) designed to enhance safety and longevity of your investment. Each battery has an onboard BMS with:
Enduro Power batteries can be connected in parallel. Parallel connections allow you to increase the ampere hour (Ah) capacity of the battery bank while maintaining the same voltage. Enduro Power’s high performance BMS supports up to 12 batteries wired in parallel. When possible, for best results we recommend using larger ampere hour (Ah) batteries to build larger capacity battery banks to reduce the number of batteries connected in parallel. This helps to reduce the number of connections which reduces the chance for inefficiencies and will make it easier to keep your LiFePO4 batteries in balance within the battery bank.Example: 3 x 12V200Ah is more efficient than 6 x 12V100Ah to build a 12V 600Ah battery bank.
Enduro Power batteries can be connected in series. Series connections allow you to increase the voltage of the battery bank while maintaining the same ampere hour (Ah) capacity. Enduro Power batteries can be connected in series in 24V, 36V and 48V configurations. When possible, for best results we recommend using a battery closer to your desired system voltage. This helps to reduce the number of connections which reduces the chance for inefficiencies and will make it easier to keep your LiFePO4 batteries in balance within the battery bank.Example: 1 x 24V100Ah is more efficient than 2 x 12V100Ah wired in series due to less connections and simplified battery bank design that promotes better cell balancing.
If you are data driven junkies like the Enduro Power team it is advised to use a battery monitor that calculates ampere hours consumed to accurately display your state of charge (SOC). Voltage based battery monitors traditionally used with Lead-Acid batteries will not provide accurate SOC for LiFePO4 batteries.
