This is a 48-volt, 314Ah LiFePO4 (Lithium Iron Phosphate) battery built for outdoor wall-mount installation, with internal heating for cold-weather charging protection. It's designed for off-grid and backup power systems where the battery lives outside the conditioned space — garages, exterior walls, sheds.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Battery specification sheets rarely tell you what happens in the field: whether a battery can actually survive a cold garage overnight, or whether its BMS will lock it out mid-charge in freezing weather. This page sticks to what EG4 has published for this SKU and flags anywhere the manufacturer data is incomplete, so you know exactly what you're buying and what still needs confirming with a specialist before you order.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate). This is an outdoor-rated wall-mount unit, distinct from EG4's indoor wall-mount and free-standing/server-rack lines. The manufacturer source data references a related "Indoor WallMount Battery 48V 314Ah 16kWh" model, but this SKU is the outdoor/all-weather variant.
[NEEDS VERIFICATION]: Exact enclosure dimensions, net weight, terminal type, cycle life figure, BMS continuous/peak discharge amperage, and precise cold-weather operating temperature range were not present in the supplied manufacturer data for this specific outdoor SKU.
Wiring & Configuration Limits (Series/Parallel)
[NEEDS VERIFICATION]: The supplied manufacturer data does not state the maximum series or parallel expansion limit for this outdoor wall-mount model. Do not assume series/parallel limits from other EG4 battery lines apply to this unit. Confirm the rated configuration limit with Zonna Energy or EG4 documentation before wiring multiple units together.
This battery is NOT rated for use as a cranking/starter battery. It is NOT to be mixed with lead-acid, AGM, or Gel batteries in the same bank, and it is NOT to be paired with lithium batteries of a different age or state of health without a qualified system design review.
Pro-Installer Tip
Cold-weather installations are where lithium battery banks fail early. Charging any lithium cell below freezing without protection accelerates lithium plating on the anode, which permanently reduces usable capacity and can trigger a BMS lockout that leaves the whole bank unresponsive. This unit includes internal heating intended to address that risk — but heater function still draws on the battery's own charge, so undersized solar arrays or generators in cold climates can leave the heater underpowered on the coldest mornings. Use a shunt-based battery monitor to track real state-of-charge and confirm the heater is cycling before you leave a system unattended through winter. As a professional standard, keep discharge within the 80–100% DoD range typical for LiFePO4 chemistry, and never assume "lithium" alone means "cold-immune" — heated does not mean unlimited.
Key Benefits
- Outdoor-rated wall-mount form factor — frees up interior wall or rack space
- Internal heating for cold-weather charging protection
- LiFePO4 chemistry — generally supports deeper discharge and longer service life than lead-acid alternatives

Compatibility & Fitment
This battery is compatible with 48V off-grid and backup systems designed for lithium battery banks. It is NOT compatible with standard lead-acid battery chargers — use only a charger or inverter/charger rated for LiFePO4 charge profiles. It is NOT intended for indoor-only installation contexts where an all-weather enclosure isn't required, though it can also be installed indoors if local code allows.
[NEEDS VERIFICATION]: Specific inverter/charge controller compatibility list and communication protocol (e.g., CAN/RS485) were not included in the supplied manufacturer data.
FAQ
Is this battery safe to charge in freezing temperatures?
This model includes internal heating intended for cold-weather charging protection. Exact operating temperature thresholds were not included in the manufacturer data supplied for this listing — confirm the rated charge temperature range with Zonna Energy before installing in an unheated outdoor space.
Can I mount this battery outdoors year-round?
Yes, this is the outdoor/all-weather wall-mount variant, distinct from EG4's indoor-only wall-mount battery.
Can I wire multiple units together for a larger bank?
Series/parallel expansion limits for this specific outdoor SKU were not provided in the source data. Confirm the maximum configuration with Zonna Energy before wiring more than one unit together.
Is this a starter/cranking battery?
No. This is a deep-cycle storage battery and is not rated for engine starting or cranking applications.
