YABO 2000+ Cycles Long Life 12.8V 100Ah LiFePO4 12 Volt Lithium Battery

Nominal voltage is 12.8V and nominal capacity is 100Ah (measured at 0.2C), providing 1280Wh of energy.

Rated for 2000 cycles at 0.2C charging/discharging until the battery reaches approximately 70% of its original capacity.

Standard charging: charge to 14.6V at a constant current of 0.2C (20A) then hold at 14.6V until current falls below 0.02C. Recommended charging voltage range: 14.0–14.6V. Standard charging current is 20A and maximum charging current is 50A.

Standard continuous discharge current is 50A, max continuous current is 80A, and max pulse (short-term) current is 200A for under 3 seconds. Discharge cut-off voltage is 10.0V.

Charge temperature range: 0°C to 45°C (32°F to 113°F). Discharge temperature range: -20°C to 60°C (-4°F to 140°F). Storage temperature: 0°C to 45°C (32°F to 113°F). All ranges at roughly 60±25% relative humidity.

Internal resistance is ≤50 milliohms. Self-discharge is ≤3.5% per month at 25°C.

Uses IFR32700 N65 cells in a 4S17P configuration (LiFePO4 chemistry).

Dimensions listed as L*W*H*TH: 328*172*216*216 (mm) per the product spec. Weight is approximately 12.5 kg. Terminal type is M8.

Yes — the battery is rated IP55 for protection against dust ingress (limited) and water jets.

It can replace a 12V lead-acid battery in many systems, but you should verify charger/inverter/alternator settings (charging voltage, charge algorithm and no equalization/float at lead-acid levels that exceed LiFePO4 specs). Confirm equipment compatibility and disable lead-acid-specific charging modes if necessary.

The provided product specification does not explicitly state details about a BMS. Check with the seller or manufacturer to confirm whether a BMS is integrated and what protections (overcharge, over-discharge, short-circuit, cell balancing) it provides.

Store in a cool, dry place within the specified storage temperature (0°C to 45°C). For long-term storage, keep the battery at partial state of charge (commonly ~40–60%) and check/recharge every 3–6 months to avoid deep discharge. Avoid storing fully discharged or at full charge for long periods.

Mount securely to prevent movement and protect terminals (M8) from short circuits. Ensure adequate ventilation if installed in confined spaces and protect from direct water exposure despite IP55 rating. Observe polarity markings and use appropriate cable size for the 50–80A continuous currents.

Use a compatible charger and charging profile, avoid short circuits, do not puncture or crush the battery, keep away from high heat or open flames, follow manufacturer handling guidance, and recycle or dispose of the battery according to local regulations.

Warranty and after-sales support are not specified in the provided details. Contact the seller or YABO manufacturer directly for warranty terms, certification documents, and technical support.
