LiFePO4 battery packs: the storage chemistry
LiFePO4 is the largest chemistry family in this range, and the natural starting point for energy storage, solar systems, backup power and any application where long cycle life matters more than the smallest possible size.

LiFePO4 chemistry trades some energy density for stability and cycle life. In practice that means a LiFePO4 pack is larger and heavier than a Li-ion pack of the same capacity, but it tolerates many more charge cycles and holds a flatter voltage through discharge. For a solar home system, a backup supply or a vehicle house battery, that trade is usually the right one: the pack is bought for years of daily cycling, not for the smallest outline. For a handheld device where every gram counts, it is usually the wrong one, and Li-ion or Li-polymer fits better.
The voltage ladder is the practical way to read this family. A 12V-class pack (12V or 12.8V nominal) suits RVs, camping, alarm systems, small solar systems and 12V equipment. A 24V pack suits larger storage and marine systems. A 48V pack suits home storage, larger solar systems and light electric vehicles. Higher-voltage packs — 51.2V, 76.8V and beyond in the wider range — serve industrial storage and traction uses. The detail pages on this site illustrate the bottom of that ladder: a 12V 100Ah pack with a metal shell and a 12V 200Ah pack with a display, both for solar power and energy storage, and a compact 12.8V 10Ah battery for camping, alarm systems and emergency lighting.
Protection is built into the LiFePO4 listings on this site: the solar-pack listings describe a built-in PCM protection board covering over-discharge, over-charge and short circuit, and the compact 12.8V listing describes a built-in smart BMS covering overcharge, over-discharge, overload and short circuit. Those are listing statements for those models, not a family-wide protection claim, and a buyer should confirm the protection of the exact model in writing. Certificate names on the solar-pack listings are CE, RoHS, MSDS and UN38.3; the compact listing states no certificate, and this site does not fill that gap.
Sizing a LiFePO4 pack starts from energy, not from amp-hours alone. Multiply nominal voltage by capacity to get watt-hours, compare that with the load's daily energy need, and allow for the depth of discharge the application actually uses. The solar-storage guide on this site walks through that calculation in general terms; the model listings supply the voltage and capacity figures to put into it.
How to choose in this family
Fix the chemistry first, then the voltage and series count, then the capacity. Check the exact model listing for its own dimensions, protection, certificate set, minimum order and lead time — those values belong to that listing and do not transfer to other models. If no listed size fits your enclosure, the custom route covers custom dimensions and configurations; describe the enclosure and the electrical requirements rather than asking for a general price.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the chemistry. If a page on this site matches, quote its model description and listing details. If nothing matches, say so and describe the chemistry and voltage you need, so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the price basis and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom design, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model description if you have one, and the documents you need. That is the whole inquiry — no separate form, no account, no extra step.
What to send us now
Send one message with your device type, the space the pack must fit, the voltage and capacity you need, the peak current if it matters, and the model description if a page on this site already matches. Add the documents you need — certificates are available upon request — and whether you need a listed model or a custom design. Use the contact page or write to [email protected], or call +86-755-25629920. A specific message like that is what turns a range of hundreds of models into a short, answerable question.
