Lead-to-Lithium Battery 12.8V 100Ah - Lead-to-Lithium series product image
The Lead-to-Lithium Battery 12.8V 100Ah (model SCLFP-12.8V-100) is a direct drop-in LiFePO4 replacement for 12V lead-acid batteries used in recreational vehicles, marine vessels, golf carts, solar off-grid systems, and UPS backups. Delivering 1280Wh from a 33 by 17.2 by 21.5 centimeter chassis that matches the footprint of a standard group-size lead-acid battery, this 100Ah lithium upgrade provides more usable capacity, a 100A discharge current, and dramatically longer cycle life without any modification to existing charging hardware. Unlike lead-acid, which typically delivers 300 to 500 cycles, CMJ Solar's LiFePO4 cells provide 2000 to 4000 deep cycles, meaning end users replace the battery far less often and enjoy consistent voltage throughout the discharge curve. The built-in BMS protects against overcharge, over-discharge, short circuit, and temperature extremes. The 12.8V nominal voltage is fully compatible with 12V alternators, solar charge controllers, and inverter chargers. Each unit carries CE, UN38.3, and MSDS certifications and is backed by a 5-year warranty. For distributors serving caravan, marine, and off-grid solar markets, the 12.8V 100Ah is one of the highest-volume lithium replacement SKUs available. CMJ Solar manufactures directly in Jiangmen, Guangdong and offers factory-direct wholesale pricing, OEM labels, and bulk container shipping. Request a distributor quote at cmjsolar.com.

Product Overview

Is the SCLFP-12.8V-100 the Right Capacity for You?

Best suited for

The 1280Wh 12.8V 100Ah is the standard large 12V lithium battery, ready for multi-day off-grid cabins, full motorhome and camper house systems, marine house banks, solar signage and lighting fleets, and backup systems paired with a 12V inverter. It sustains 100A continuous — about 1200W — so it can run AC appliances and surge loads that smaller packs cannot, while the 33 by 17.2 by 21.5 cm case remains a manageable single-person carry.

Typical loads this capacity handles

Typical loads for the 100Ah pack: a fridge, lighting, router, TV, and device chargers for one to two days, with a 1000W inverter available for kitchen appliances and tools in short sessions. It also starts small pump and fan motors that trip smaller packs. This is the pack most often specified when customers ask for a normal off-grid setup in one battery.

Estimated runtime

Runtime example: roughly 1,150Wh usable. A fridge plus lights averaging 80W runs for about 14 hours; a 40W base load alone lasts nearly 29 hours. A 1,000W inverter load gives just over an hour of continuous run, enough for short cooking or tool tasks rather than sustained appliance use.

Sizing advice

Choose the 100Ah when a fridge, inverter, lights, and charging all run from the same bank and you want one battery with days of reserve and shallow daily cycling. It is also the best base for parallel expansion into larger banks. Pick the 100E Economy version only if your load stays below 80A and cost is the priority; otherwise this standard model gives the higher discharge headroom.

Frequently Asked Questions

What warranty does this product come with?

The Lead-to-Lithium Battery 12.8V 100Ah 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 power my home during an outage?

The Lead-to-Lithium Battery 12.8V 100Ah 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 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 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.
