LG Energy Solution. The engine room.
One of the world's largest battery cell makers — behind the RESU home range and lithium-ion cells used right across the storage industry. Premium NMC and LFP cells, built with Lamination & Stacking pouch design. This is the quality that lives inside the batteries we install.

Why the cell
is the engine room.
Lamination & Stacking
LG cells use a flat, laminated pouch design that layers the cell sections rather than rolling them. This supports higher energy density and even heat dissipation across the cell — the foundation of long, stable cycle life.
NMC Energy Density
Nickel-manganese-cobalt cells pack more usable energy into a compact footprint. It's the chemistry behind the RESU home range and millions of EVs — proven across some of the most demanding battery applications on earth.
LFP for Storage
LG now manufactures lithium iron phosphate cells at scale specifically for energy storage. LFP runs cooler, lasts longer and offers excellent thermal stability — well suited to daily home cycling.
Proven at Every Scale
The same cell pedigree spans home storage, electric vehicles and grid-scale projects worldwide. Cells engineered for vehicle reliability bring that same discipline to the battery on your wall.
RESU 10-Year Warranty
LG's RESU home systems are backed by a 10-year warranty with strong capacity-retention terms — Prime models guarantee 70% of capacity after a decade, subject to throughput limits. Confidence that starts at the cell.
High Efficiency
Round-trip efficiency around 94.5–97.5% means very little energy is lost moving power in and out of the cell. More of your solar reaches your home — not wasted as heat in conversion.
Where LG cells
do their work.
Home Storage
The RESU range — including the 10H Prime (9.6kWh) and 16H Prime (16kWh) — uses LG's NMC cells to deliver high-density home storage with 5–7kW continuous power and a 10-year warranty.
Energy Storage
LG's standard LFP pouch cells are now built at scale for energy storage systems — the cool-running, long-cycle chemistry increasingly chosen for home and grid batteries across the industry.
Proven Pedigree
The same cell engineering powers electric vehicles and grid-scale projects worldwide. That automotive-grade discipline is what sits inside the home batteries we recommend.
