  • Our take on the 12V 100AH LiFePO4 Deep Cycle Lithium Battery

    The SunGoldPower 12V 100Ah is a lithium iron phosphate deep-cycle battery rated at 12.8V and 1,280Wh, with a claimed 4,000+ cycles at 80% depth of discharge. It stands out from many rivals by combining a built-in 100A BMS, an IP65 case, self-heating for cold charging, and both an LCD and Bluetooth state-of-charge monitoring. It suits RV, van, boat, camping and off-grid solar users who want a drop-in 12V lithium upgrade with cold-weather protection. Against basic 100Ah LiFePO4 batteries it adds monitoring and heating, but it is heavier and bulkier than heated batteries built for tight compartments.

    Pros
    • Built-in 100A BMS protects against overcharge, over-discharge and short circuits
    • Self-heating lets it charge in sub-freezing conditions
    • IP65 case resists dust and water spray
    • LCD and Bluetooth show voltage and state of charge
    • Series or parallel up to four units for 12V, 24V or 48V banks
    • 4,000+ cycle rating at 80% depth of discharge
    Cons
    • Heavier and larger than some 100Ah LiFePO4 rivals
    • Self-heating draws from the battery and slows cold charging
    • Bluetooth app is an extra dependency for monitoring
    • Not a true drop-in for lead-acid charging profiles without a lithium-compatible charger

    About the 12V 100AH LiFePO4 Deep Cycle Lithium Battery

    This is a 12.8V 100Ah lithium iron phosphate (LiFePO4) deep cycle battery that stores 1,280Wh. It is rated for 4,000+ cycles at 80% depth of discharge. It is used in RVs, vans, boats, camping and off-grid solar systems.

    The case is rated IP65, and a self-heating function is included.

    Voltage and state of charge show on the built-in LCD or on your phone over Bluetooth. Batteries can be connected in series or parallel, up to four of each, to build 12V, 24V or 48V banks.

    Questions and answers

    Can it be charged below freezing?
    Yes. The self-heating function warms the cells so charging can proceed in sub-freezing temperatures, which plain LiFePO4 batteries cannot do safely.
    How many batteries can I connect together?
    Up to four in series and up to four in parallel. That allows 12V, 24V or 48V banks, with the parallel limit set by the 100A BMS.
    How do I check the charge level?
    The built-in LCD shows voltage and state of charge at the battery, and Bluetooth sends the same data to a phone app.
    Is it a direct replacement for a lead-acid battery?
    Physically it fits many Group 27 and Group 31 trays, but you need a charger and solar controller with a lithium LiFePO4 profile. Lead-acid charging voltages are not ideal.
    What can a 100Ah battery run?
    At 1,280Wh it can run a 12V fridge for a day or more, lights and fans for several days, or a modest inverter load. Heavy loads like air conditioners need a larger bank.
    Does it work for trolling motors?
    Yes. The 100A continuous BMS covers most 12V trolling motors, and the IP65 case handles spray. Check your motor's peak draw against the 100A limit.
    Where is the 12V 100AH LiFePO4 Deep Cycle Lithium Battery cheapest?
    At Amazon, for $249.99, as of our latest check.
    Where can I buy the 12V 100AH LiFePO4 Deep Cycle Lithium Battery?
