LiFePo4 20Ah Lithium Battery 12.8V

DescriptionIf using more than one of these batteries you MUST use a battery balancerDo not connect smart (with Bluetooth) and non-smart lithium battery packs in series or parallel as this will invalidate the warranty. They must all be of the same typeIntroducing the Energiestor PowerCore LiFePO4 20Ah 12.8V Lithium Battery, a new benchmark for portable power. Powered by advanced Lithium Iron Phosphate chemistry, it provides consistent power, a long service life, and reliable safety, all within a light and compact design.Whether you’re installing solar panels, going camping, powering a small boat, or traveling in an RV, this battery supplies clean, reliable energy exactly where you need it.Built to outperform lead-acid batteries, the PowerCore 20Ah model has twice as much usable capacity, charges faster, and will last many years longer.It’s protected by a built-in Battery Management System (BMS) that prevents over-charge, over-discharge, overcurrent, and short-circuiting, giving you maintenance-free performance with complete peace of mind. If more than one battery is used in tandem, it must always be connected via a battery balancer. Mixing Bluetooth-enabled and non-smart lithium packs voids the warranty and decreases overall system stability.Key Benefits of the Energiestor 20Ah LiFePO4 Battery Exceptional Power in a Compact SizeWeighing only 2.88 kg, this compact 20Ah LiFePO4 battery packs an impressive 256 Wh of energy! This is less than half the weight of a competitive lead-acid battery! It holds voltage constant during use. This way, your 12V devices and systems will operate effectively from start to finish! Extended Battery LifeThis battery has up to 5000 cycles at 50 per cent depth of discharge or 3000 cycles at 80 per cent depth of discharge, by far outliving lead-acid competitors, thanks to superior LiFePO4 chemistry. It provides long term serviceability of solar, marine, and mobile systems and is because of a design life of 15 to 20 years. Safe, Clean, and Stable PowerLiFePO4 has been described as the safest lithium chemistry. Individual Energiestor batteries are certified to UN38.3 including altitude, vibration, short-circuit, thermal and shock tests. The outcome: a safe 12.8V 20Ah battery with a consistent performance and the absence of the possibility of gas release, acid spillage, and thermal runaway. 100 % Depth of Discharge CapabilityWhile lead-acid batteries allow only 30–50 % discharge before risking damage, the rechargeable 20Ah LiFePO4 battery can safely reach up to 100 % DOD. That means you can draw every bit of energy available, doubling usable capacity and maximizing efficiency for high-demand applications. Maintenance-Free and Environmentally FriendlyNo acid, no fumes, no water top-ups. This lightweight 20Ah lithium battery is totally sealed and can be mounted in any position-even upside down-without risk. With no gases emitted during charging, there’s no need for ventilation, and it is a sustainable, ecologically friendly energy option.Performance SpecificationsNominal Voltage: 12.8 V (range 12.5 – 13.2 V)Rated Capacity: 20 AhEnergy Capacity: 256 WhContinuous Discharge: 20 APeak Discharge (3–5 s): 40 AMaximum Charge Current: 10 ACharge Voltage: 14.6 – 14.8 VCycle Life: 5000 cycles @ 50 % DOD / 2500 cycles @ 100 % DODOperating Temperatures: Charging 0 °C – 45 °C Discharging −20 °C – 60 °CDimensions: 173 × 167 × 122 mmWeight: 2.88 kgCasing: Durable ABS PlasticProtection: Integrated BMS for over-charge, over-discharge, overcurrent, and short-circuit safetyDesign Life: 15 – 20 yearsWarranty: 2 yearsThis portable 20Ah lithium battery delivers steady, high-efficiency power ideal for solar storage, LED lighting, communication gear, and backup systems.Why Choose Lithium Over Lead-AcidLead-acid technology is outdated, heavy, inefficient, and short-lived. Typical lead-acid batteries only use half their capacity, require constant maintenance, and can emit explosive gases during charging.By contrast, the Energiestor 12.8V LiFePO4 20Ah battery offers:Higher usable energy: roughly twice the discharge depth of lead-acidZero maintenance: sealed and gas-free design.Consistent power output: stable voltage delivery across discharge cycles.Longer lifespan: thousands of cycles before any noticeable capacity drop.With the advantages of safety, performance, and even sustainability, LiFePO4 has been considered the preferred battery type for renewable energy, marine power, and off-grid living.Battery Performance Terms: ExplainedDepth of Discharge (DOD): The portion of total capacity used in each cycle. LiFePO₄ chemistry easily handles deep discharges with minimal wear.Cycle Life: The number of complete charge-discharge cycles a battery is capable of before its capacity falls. An Energiestor PowerCore lasts up to 5000 cycles, which equates to approximately 10-15 times the life of a lead-acid battery.Amp-Hours (Ah): A measure of stored charge. For example, this 20 Ah battery can supply 1 A for 20 hours or 5 A for 4 hours.Watt-Hours (Wh): The total stored energy (Voltage × Capacity). Here, 12.8 V × 20 Ah = 256 Wh is suitable for keeping small electronics, lights, and mobile gear powered up.System Integration and CompatibilityThis deep-cycle 20Ah lithium battery can be connected in series or parallel depending on your power requirements. Connect up to eight units in parallel to build a battery bank up to 160 Ah, or use series connections to achieve 24 V or 48 V systems.Always connect several batteries with a battery balancer to ensure equal charge and discharge rates. Never mix smart and non-smart packs or mix different brands, as that will affect system performance and may void the warranty.The Energiestor LiFePO4 20Ah 12.8V battery is compatible with most lead-acid charging systems, though a dedicated lithium charger is recommended for the best lifespan and efficiency. It’s also fully suited for solar charging setups, ensuring maximum power harvest with minimal losses.Conclusion The Energiestor PowerCore 12.8V LiFePO4 20Ah Lithium Battery delivers the perfect balance of safety, longevity, and performance. Its lightweight construction, deep-cycle capability, and smart protection system make it ideal for renewable energy systems, RVs, marine power, and portable applications.Offering up to 5000 cycles, fast charging, and maintenance-free operation, this battery is a future-ready replacement for outdated lead-acid models. When you need dependable power in a compact design, trust Energiestor’s LiFePO4 20Ah battery, built for endurance, engineered for performance.
