12.8V 312Ah LiFePO4 Battery Pack — 12312Y-01 / 12314Y-01 (12.8V) — 12312Y-01 / 12314Y-01 · 12.8V
LiFePO4 Battery Packs

LiFePO4 Battery Pack 12312Y-01 / 12314Y-01 (12.8V)

12312Y-01 / 12314Y-01 · 12.8V

Four kWh that goes where you go.

The 12.8V sibling packs four kilowatt-hours into 30.5kg — light enough to move, big enough to matter. It powers 12V loads directly in RVs, boats, street lighting and base stations, and builds into larger systems through series/parallel combination.

01

Drop-in 12V format

Standard 12V LiFePO4 parameters (14.6V charge, 10.0V cutoff) work with most 12V chargers, inverters and solar controllers.

02

Half the weight, six times the life

At 30.5kg versus ~85kg for comparable lead-acid Ah, and 6,000+ cycles versus 300–500 — the lifetime cost math is not close.

03

100A discharge headroom

Runs inverters up to roughly 1kW continuous, plus motors and DC loads, with 50A standard / 80A fast charging.

04

BMS on board

Over-charge, over-discharge, over-current and short-circuit protection with a SOC display, in an 8S1P configuration.

FAQ

12312Y-01 / 12314Y-01 FAQ.

What can 4kWh run in an RV?

A full weekend of typical use: LED lighting, a 12V fridge, water pump, phone charging and a TV — roughly 3–4 days without sun, and indefinitely with 300–400W of solar through a suitable controller.

Is it a direct replacement for my lead-acid battery?

In most 12V systems yes — check that your charger has a lithium mode or adjustable voltage (14.6V). Our NQ/NS smart chargers have a dedicated lithium profile for exactly this.

Can I combine packs for 24V or 48V?

Yes: two packs in series make 25.6V, four make 51.2V; parallel connection multiplies capacity. Use matched packs and keep series strings balanced.
