Lead-to-Lithium Battery 12.8V 30Ah
Model: SCLFP-12.8V-30

Product Overview
Is the SCLFP-12.8V-30 the Right Capacity for You?
Best suited for
The 384Wh 12.8V 30Ah is the entry point for practical daily cycling: it can run several LED lights, a router and electronics, or a small portable fridge for a partial evening. It is the common choice for small caravan and camper conversions, fishing and camping boxes, surveillance and telecom standby, and 12V kiosks that previously used 28 to 35Ah gel batteries. The 30A discharge supports roughly 360W continuous, enough for modest DC loads but still short of meaningful AC inverter use.
Typical loads this capacity handles
Typical loads for the 30Ah pack: four or five LED points for an evening, a router and set-top box for 8 to 10 hours, phone and tablet charging, or a small 12V fridge running for a few hours. A 300W inverter works for laptop and camera chargers but will trip if you add a hairdryer, kettle, or microwave. For overnight compressor-fridge cycling, plan for the 45Ah or larger.
Estimated runtime
Runtime example: about 345Wh of usable energy at the recommended depth of discharge. A 25W mix of LED lighting, router, and device charging lasts close to 14 hours; an intermittent 40W load lasts around 8 to 9 hours. A 100W inverter load drains it in roughly 3.5 hours, so inverter use should stay occasional.
Sizing advice
Pick the 30Ah when you need real overnight capacity in a compact 22.3 by 9.5 by 17.5 cm case that matches common 30Ah lead-acid trays. It pairs well with small solar panels and a 12V charge controller. If you plan to add an inverter, run a compressor fridge through the night, or want two days of reserve, move up to the 45Ah or 50Ah rather than running this pack near its ceiling every day.

Frequently Asked Questions
What warranty does this product come with?
The Lead-to-Lithium Battery 12.8V 30Ah comes with a 5-year warranty covering the LiFePO4 battery cells and integrated BMS. Our LiFePO4 cells are rated for 2,000-4,000 charge-discharge cycles, providing 5-10 years of reliable daily use under normal operating conditions. Spare parts and technical support are available throughout the warranty period.
What is the MOQ (Minimum Order Quantity)?
The MOQ is typically 20 units per model for standard products. Sample orders of 1 unit are welcome for testing and evaluation. For OEM/ODM custom packaging or private labeling, the MOQ is 500 units. Contact our sales team for specific pricing based on your order volume.
How long can the Lead-to-Lithium Battery 12.8V 30Ah power my home during an outage?
The Lead-to-Lithium Battery 12.8V 30Ah provides 384Wh of stored energy (approximately 346Wh usable at 90% depth of discharge). At an average essential-load draw of 500W (lights, router, refrigerator, and TV), it can sustain power for approximately 0.7 hours. At 1,000W, runtime is approximately 0.3 hours. Actual runtime depends on total connected load and usage patterns.
Is this a direct drop-in replacement for lead-acid batteries?
Yes. The Lead-to-Lithium Battery 12.8V 30Ah is designed as a direct drop-in replacement for equivalent lead-acid batteries. It matches the standard form factor and terminal positions of conventional lead-acid batteries while delivering 12.8V LiFePO4 chemistry. Simply remove the old lead-acid battery, place the LiFePO4 unit in the same compartment, and connect the existing cables. We recommend setting your charger or charge controller to the LiFePO4 charging profile for optimal performance and lifespan.
How long does the LiFePO4 battery last?
The LiFePO4 cells in the Lead-to-Lithium Battery 12.8V 30Ah are rated for 2,000-4,000 charge-discharge cycles before capacity drops to 80% of the original rating. In a typical daily-cycle residential application, this translates to 5-10 years of service life. LiFePO4 chemistry also offers superior thermal stability and safety compared to lead-acid or NMC batteries, with no maintenance required.
