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

    The GuaiGLong 12V 100Ah is a lithium iron phosphate deep-cycle battery rated at 100 amp-hours, roughly 1.28 kWh of usable energy. LiFePO4 chemistry gives it a longer cycle life, lighter weight and steadier voltage under load than a flooded or AGM lead-acid battery of the same capacity. It suits trolling motors, RV house banks, off-grid solar, campers and backup power where a sealed, low-maintenance battery matters. Compared with premium brands, it is a budget-tier option, so buyers should weigh its lower cost against thinner documentation and fewer verified cycle-life claims.

    Pros
    • LiFePO4 chemistry resists deep discharge better than lead-acid
    • About half the weight of a comparable AGM battery
    • Sealed and maintenance-free, safe to mount in most positions
    • Steady voltage output as it discharges
    • Built-in battery management system protects the cells
    Cons
    • Budget brand with limited track record and documentation
    • Cold-weather charging needs care; below freezing, charging must stop
    • Needs a lithium-compatible charger or solar controller
    • Not a drop-in for every lead-acid charging setup

    Questions and answers

    Is this a good replacement for a lead-acid deep-cycle battery?
    Yes for capacity and weight, but check your charger. LiFePO4 needs a lithium profile or a charger with an adjustable absorption voltage, otherwise the battery may not fully charge.
    Can it run a trolling motor?
    A 100Ah lithium battery handles most small to mid-size trolling motors for a full day. Check your motor's amp draw and fuse it to the battery's BMS current limit.
    Can I charge it below freezing?
    No. Charging a LiFePO4 battery below 0°C damages the cells. Unless the spec sheet lists low-temperature charging protection, keep it above freezing while charging.
    How many batteries can I connect together?
    Series and parallel limits depend on the BMS. Confirm the manufacturer's stated maximum for series voltage and parallel strings before building a bank.
    What is in the box?
    Typically the battery alone, sometimes with terminal bolts. A charger and mounting hardware are usually sold separately, so plan for those.
    Where is the 12V 100Ah LiFePO4 Lithium Deep Cycle Battery cheapest?
    At GuaiGLong, for $319.99, as of our latest check.
