LF4050-13 12V 30Ah LiFePO4 Battery Pack
The LF4050-13 is a 12V 30Ah LiFePO4 pack listed for off-grid applications. Nominal voltage is 12.8V, listed energy 384Wh, and cycle life 2000 cycles, in a plastic casing with an M6 terminal and an IP55 rating. At about 3.5kg and 223×95×175×175 mm, it is a mid-size 12V pack: heavier and larger than the 12Ah and 15Ah packs, well below the 280Ah and 300Ah packs.
- LiFePO4 packs in 12V, 24V and 48V
- 7 x 12V models with full spec tables
- Portable stations and hybrid NiMH fitments
- Certificates available upon request
No founding year, headcount, phone or named contact is published on this site: those records conflict between sources and are not settled. Contact goes through the inquiry form.
Cell format is IFR32700 N60 in a 4S5P arrangement. Charging is 15A with a 30A maximum, discharging 15A with a 30A maximum continuous, and the maximum pulse is 60A for under three seconds. Internal resistance is listed at no more than 55mΩ.

Values are recorded exactly as listed for this model. Where a figure is absent, it was not read for this model and is not inferred from another model.
Off-grid use, read carefully
“Off-grid” on this page means only that the listing names off-grid applications for this model. It does not by itself establish a solar charge controller, an inverter pairing or a system size: those are system decisions that depend on the load, the charge source and the protection set, and they belong in the pre-order confirmation with the supplier.
The common 12V listing claims apply here as listing claims: automatic protection against over-charge, over-discharge, over-current and over-temperature, internal cell balancing, maintenance-free operation, about 40% to 50% of the weight of a comparable lead-acid battery, and charging with most standard lead-acid chargers.
Certificates follow the site-wide line: “Certificates available upon request.” No certificate number is published. Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Off-grid sizing, honestly
An off-grid job is sized by daily energy, not by a single pack label. The 30Ah capacity and 384Wh listed energy of this model are the starting figures, and the daily load, the charge source and the number of days of autonomy decide how many packs a system needs. The listing names off-grid applications for this model, but it does not size a system, and this page does not convert a single pack's figures into a system recommendation. The 15A charging and 15A discharging figures (30A maximum charging and 30A maximum continuous), the 60A pulse limit (<3s) and the M6 terminal are the values to carry into the system conversation with the supplier.
Before ordering
Before payment, confirm MOQ, lead time, voltage, warranty and certification scope for your order.
Confirm the specification for the model actually ordered, not for a neighbouring model or a series range.
