Product Description

The Renogy CORE 12V 300Ah Self-Heating Lithium Iron Phosphate Battery 4-Pack builds a 1,200Ah bank — about 15.4kWh of storage — from four matched CORE Series batteries. Each battery carries a built-in 200A battery management system and a self-heating function that activates at 32°F, so the bank keeps accepting a charge in freezing weather. Per Renogy, the CORE Series is rated for 5,000 cycles at 80% depth of discharge.

Who This Is For

Four batteries is whole-system territory: off-grid cabins and homesteads, large RVs and toy haulers running air conditioning through an inverter, boats with substantial house loads, and backup power banks that need to carry a household through an outage. Wired in parallel, this 4-pack reaches Renogy's documented parallel limit for a 12V bank; the same four batteries can instead be wired in series-parallel for 24V or 48V systems. If you are starting smaller, the single CORE 12V 300Ah battery uses the same platform, so you can standardize now and match later.

Key Features

1,200Ah of combined capacity from four 12V 300Ah lithium iron phosphate batteries — about 15.4kWh based on Renogy's system ratings
Self-heating function activates at 32°F using 200W heating elements, per Renogy, with charging rated down to -4°F
5,000 cycle life at 80% depth of discharge, per Renogy
200A maximum charge and discharge current per battery, managed by a built-in 200A BMS with low-temperature charge and discharge cut-off
Flexible bank design: 12V parallel, or series-parallel for 24V and 48V systems, up to 16 batteries total per Renogy
IP65 dust and water protection rating
60.63 lb per battery — 242.5 lb for the full set, far less than lead-acid banks of comparable usable capacity

Why Renogy

Renogy has built solar and battery equipment for the off-grid market for over a decade and publishes full manuals, spec sheets, and warranty terms for its products. The CORE Series carries a 5-year prorated material and workmanship warranty, and because OffGrid Horizon is an authorized Renogy dealer, your coverage is valid from day one. A bank this size pairs well with a substantial solar array such as the Renogy 320W N-type monocrystalline panel 4-pack.

Bank Design: What Four Batteries Give You

Renogy rates a full 16-battery CORE bank at 61.44kWh, which works out to 3.84kWh per battery — about 15.36kWh for this 4-pack. In a 12V parallel bank, that is 1,200Ah with up to 800A of combined continuous discharge capability across the four BMS units. Wired as 2S2P you get a 24V, 600Ah bank; as 4S, a 48V, 300Ah bank for systems built around 48V inverters. Renogy requires all banked batteries to be the same model and generation, which is the practical argument for buying the full set at once.

Warranty & Support

Renogy backs the CORE Series with a 5-year prorated material and workmanship warranty (see Renogy's warranty terms). OffGrid Horizon is a family-owned authorized Renogy dealer — call us at (302) 496-3554 for help with troubleshooting, warranty claims, or system planning.

Shipping

This 4-pack ships within the US by LTL freight on a pallet — the set weighs over 240 lb packed. The carrier will typically call ahead to schedule a curbside delivery. Before signing the delivery receipt, count the packages and inspect for visible damage — note anything you find on the receipt or refuse the damaged piece. This keeps your claim options intact.

Frequently Asked Questions

Can I run this 4-pack as a 24V or 48V bank?

Yes. Per Renogy, the CORE Series supports up to 4 in series and 4 in parallel, so this set can be configured as 12V (4P), 24V (2S2P), or 48V (4S). Follow the user manual's wiring and balancing procedures.

Can these batteries charge below freezing?

Yes. Per Renogy, the self-heating function activates at 32°F and the rated charge temperature range extends down to -4°F, with BMS low-temperature cut-offs protecting the cells.

How much energy does this 4-pack store?

About 15.36kWh, based on Renogy's 61.44kWh rating for a full 16-battery bank (3.84kWh per battery).

Do they have Bluetooth monitoring?

No. Per Renogy, this model is not compatible with the Bluetooth module; Renogy recommends a 500A shunt-based battery monitor (sold separately) for state-of-charge readings.

Can I add more batteries later?

Up to 16 total per Renogy, but all must be the same model and generation. Renogy's guidance favors buying a bank together so cells age evenly.

What charger settings should I use?

Use a lithium (LI) charge profile with a 14.4V charge voltage, per Renogy. Each battery accepts up to 200A of charge current, so a parallel bank can absorb high charge rates from large arrays or inverter chargers.

How heavy is each battery to handle?

60.63 lb each, in a 20.55 x 9.45 x 8.62 in case — a two-person lift is sensible, but each unit is roughly half the weight of a lead-acid battery in a similar case size.
