A LiFePO4 battery that lasts 10 times longer than lead acid, weighs a third as much and gives you its full power. Made in Shenzhen, shipped to 25+ countries.
Standard size, so it drops into most 12V systems.
4,000+ cycles, over 10 years of daily use.
Guards against overcharge, heat and short circuit.
A third of the weight of lead acid.

It does the same job as a lead acid battery. However, it does it better, for much longer, and with less weight.
4,000+ cycles means one charge a day for over a decade.
Around 11kg instead of 30kg, so it is easy to carry and install.
You can safely use almost 100% of the capacity. Lead acid gives you about half.
LiFePO4 chemistry and a smart BMS protect against overcharge, heat and short circuit.
Pick what you want to power. Then see how many hours one battery, or a few together, will run it.
Or move the slider to set your own power use.
That's more than a full day.
Estimate uses 1280Wh per battery, 95% usable for LiFePO4, 50% usable for lead acid and 90% inverter efficiency. Real results depend on your setup.

Same size slot, very different results. Here is how they compare side by side.
How many full charges before it wears out.
How much of the 100Ah you can actually use.
Lighter is better for vans, boats and roofs.
One full cycle every day.
Because it is a standard 12V size, it fits right into the systems your customers already have.
Store daytime solar power and use it at night or during load shedding.
Off grid and backup
Run lights, fridge and fans for days without a generator.
Light and compact
Power trolling motors, fish finders and cabin lights on the water.
IP65 option
A long life upgrade for home and office inverter backup.
Lead acid replacement
Keep cameras, gates and small towers running when the grid fails.
Wide temperature range
Lighter carts and longer range, with fast charging.
High discharge

A 12V LiFePO4 battery has a nominal voltage of 12.8V. It charges to about 14.4V and stays above 12.8V for most of its discharge, so your devices get steady power.
It is rated for 4,000+ cycles at 80% depth of discharge. So with one cycle per day, that is more than 10 years of use.
Yes, in most systems. The size and terminals match common 12V batteries. Just set your charger or inverter to a lithium or LiFePO4 profile.
Yes. You can connect up to 4 in series for 48V, and several in parallel for more capacity. However, always use batteries of the same model and age.
It can discharge down to −20°C. For charging below 0°C, choose our self heating option, which warms the cells first.
Yes. We offer OEM and private label with your logo, color and packaging.
You can start with a sample. After testing, you can then order a small batch or a full container.
We ship by sea, air or express with UN38.3 and MSDS documents, packed to meet dangerous goods rules.
Tell us how many units you need and where to ship. Our export team will then send unit price, lead time and shipping cost within 2 hours.
