Lead-to-Lithium Battery 12.8V 100Ah Economy
Model: SCLFP-12.8V-100E

Product Overview
Is the SCLFP-12.8V-100E the Right Capacity for You?
Best suited for
The 100E delivers the same 1280Wh as the standard 100Ah in an Economy configuration tuned for cost-sensitive 12V storage where peak current is moderate. It fits budget motorhome builds, small cabins, lighting and monitoring fleets, and backup for routers, electronics, and low-to-mid power appliances. The continuous discharge is rated at 80A (roughly 960W), so it handles most everyday DC and modest inverter loads but is not built for high-surge or maximum-output use.
Typical loads this capacity handles
Typical loads for the 100E pack: the same fridge, lighting, and electronics profile as the standard 100Ah over one to two days, as long as simultaneous draw stays under its 80A ceiling. Keep inverter use below about 900W and avoid repeated motor-start surges. If a single appliance — a large inverter, winch, or compressor — can by itself approach the limit, choose the standard 100Ah instead.
Estimated runtime
Runtime example: the same usable energy as the standard 100Ah, around 1,150Wh. An 80W fridge and lighting mix runs for about 14 hours, and a 40W base load for nearly 29 hours. Keep continuous inverter draw near 800W to stay within the Economy pack 80A current rating.
Sizing advice
Pick the 100E when the project is price-driven and your real-world draw stays comfortably under 80A — lighting, fridge, and device charging fit this well. If you regularly run a 1000W-plus inverter, air conditioning, or motor-start loads, pay the difference for the standard 100Ah and its 100A headroom. Both share the 33 by 17.2 by 21.5 cm case and the same Grade A LiFePO4 chemistry and warranty.

Frequently Asked Questions
What warranty does this product come with?
The Lead-to-Lithium Battery 12.8V 100Ah Economy 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 100Ah Economy power my home during an outage?
The Lead-to-Lithium Battery 12.8V 100Ah Economy provides 1,280Wh of stored energy (approximately 1,152Wh 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 2.3 hours. At 1,000W, runtime is approximately 1.2 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 100Ah Economy 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 100Ah Economy 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.
