Lifepo4 battery 12v

Lifepo4 battery 12v

LiFePO4 chemistry lithium cells have become popular for a range of applications in recent years due to being one of the most robust and long-lasting battery chemistries available. They will last ten years or more if cared for correctly.

Lithium Ion-as well as Lithium Iron ( LiFePo4) as a new battery technology. The cost still very high in the market. Same for the price of 12V lithium ion batteries. We noticed the majority brand in this market still selling at 600-900USD based on LiFePo4 12v 100ah pack. These products mostly come original from China. And the market team in USA, they are good at how to build brand name. Behind of the brand. Products has much less innovation. But people pay much more compared with the product cost. That’s the magic of “brand”.

We decide to step out as an OEM 12v lifepo4 battery manufacturer. And selling directly to the market with our own brand OSM. It’s maybe still not a famous brand. But our Battery is reliable, longevity, allowable discharge levels pack. Has been falling in recent years, making them more and more attractive for the average consumer. Let average consumer benefits from technology of Lithium ion batteries.

If you are consumers. You are welcome to order directly with us. If you are battery distributor. We would be glad to invite you to join us.

12v lifepo4 battery VS typical SLA?

12v lithium ion deep cycle battery is a popular standard volt to provide power to a range of appliances, RV, Solar lights, UPS and other electronics. But why people willing to spend the extra money for a lithium battery? Well, here’s why it might be worth the investment.  lithium iron  12v batteries are:

• High energy density—Much lighter in weight Smaller in Size.

Lithium ion battery with much higher energy density than any other type rechargeable batteries. A 12v 100ah lithium ion battery weighs around 26lbs. Compare that to a 60lb lead-acid deep cycle battery, and you have something that’s much more manageable to work with.

With lithium batteries, you’re looking at a Specific Energy level of around 150 Wh/kg, versus the 30-40Wh/kg that you’ll find in a normal 100ah AGM battery.

• Possible for high rate discharge

If you aren’t already aware, your normal SLA deep-cycle 12V battery should never be drained past 50% charge, or else you risk losing a significant number of lifetime recharge cycles. Depending on your daily amperage consumption, this might mean that you’d need a larger SLA battery to match your needs. However, a lifepo4 12v  battery can comfortably be drained to 20% without any damage to its lifespan. So, it’s very possible that a single 12v lithium ion battery could take the place of 2 SLA’s in meeting your daily demand.

• Much long cycle life

It is probably you are lucky person if get 400 charge cycles out of a normal AGM battery. But the advancements in lithium iron phosphate technology have changed the game, offering up to 3,000+ cycles without issue!

• Price Down

Benefit of the new energy market from China. The 12v 100ah lithium ion battery price is getting down. Now, the price is very close with AGM or Lead acid batteries. Spend less and get a lithium rechargeable battery.

A 12V LiFePO4 battery is a 4S lithium iron phosphate pack at 12.8V nominal. Mid-capacity sizes carry most enquiry volume in this range because they pair a manageable footprint with usable runtime. OSM Battery manufactures the 12V LiFePO4 range from small-format units up to high-capacity packs for wholesale, OEM and ODM supply.

Why 12V and 12.8V Are the Same Battery

A 12V LiFePO4 battery is a 4S configuration: four 3.2V cells in series, giving 12.8V nominal. That is why the same product appears under both labels in the market — “12.8V” is the true nominal voltage and “12V” is the lead-acid replacement shorthand buyers search with. Electrically the two labels describe one pack.

Capacity in this range runs from small-format units in the single-digit Ah class up to high-capacity packs above 300Ah. Stored energy scales linearly with rated Ah at 12.8V nominal, so a pack of twice the rated capacity holds roughly twice the energy in the same chemistry.

Choosing Capacity by Application

Specific configurations are documented on the product pages in this category, including the 12V 100Ah deep-cycle unit, the 12V 200Ah lithium battery and the 12V 200Ah RV battery. Weights and dimensions for each are published there rather than repeated here, because they differ by case tooling.

12V LiFePO4 or Lead-Acid — What Changes

Because usable depth of discharge differs, a LiFePO4 pack is not a strict Ah-for-Ah swap for a lead-acid battery: the replacement is often smaller in rated Ah for the same usable runtime. Match on usable energy rather than on the label.

OEM, ODM and Wholesale Supply

The 12V range is supplied on OEM and ODM terms for distributors, brand owners and equipment manufacturers, including customer branding, terminal and connector specification, custom case tooling and BMS parameter configuration. Low-volume sample orders are available for design validation before a production run.

Frequently Asked Questions

Is a 12V LiFePO4 battery the same as 12.8V?

Yes. A 12V LiFePO4 battery is 4S — four 3.2V cells in series — giving 12.8V nominal. “12V” is the lead-acid replacement shorthand and “12.8V” is the true nominal voltage; both labels describe the same pack.

How do I choose capacity for an off-grid installation?

Size on usable energy rather than label Ah, then divide by the daily load to get autonomy in days. Where runtime matters more than weight, paralleling two identical packs is preferred — check they are the same model and age first.

Can I charge a 12V LiFePO4 battery with a lead-acid charger?

Only if the charger has a LiFePO4 profile or an adjustable absorption voltage in the 14.4V to 14.6V class. A lead-acid float profile will undercharge the pack, and a desulfation or equalisation cycle will damage the BMS and the cells.

Do you supply 12V LiFePO4 batteries for OEM projects?

Yes. OSM Battery supplies the 12V LiFePO4 range on OEM and ODM terms, covering customer branding, terminal specification, custom case tooling and BMS parameter configuration, with low-volume samples available for design validation.
