About Litrium
Built by people who hate power cuts as much as you do.
Litrium exists for one reason — to put serious, safe, long-lasting lithium storage into the hands of homes and businesses who deserve reliable power. No fluff. No lock-in. Just batteries that do the work.
— Our story
Born from too many dark nights.
Litrium started where most good ideas start — frustration. Our founders lived through too many grid outages, too many ruined fridges, too many generators coughing diesel fumes through the night.
Solar panels were everywhere. But the batteries? Either ancient lead-acid tanks that died in three years, or rebranded laptop cells marketed as "solar storage." There was nothing in between that felt honest.
So we went straight to the source. We partnered with SunArk — the world's leading LiFePO₄ manufacturer — and built a store around a single promise: sell the battery we'd put in our own homes. Nothing else.
The Litrium Team
Founders · London
Four principles. Zero exceptions.
Everything we sell, service, and stand behind runs through these. If a decision doesn't pass all four, we don't make it.
One chemistry, done right
We only sell LiFePO₄. Not because it's trendy — because it's the longest-lived, safest chemistry for stationary storage. Full stop.
Support after the sale
A battery lasts 15+ years. We're here for that whole time. Real humans, real answers, real replacements under warranty — no ticket black holes.
Cleaner by default
LiFePO₄ is cobalt-free and lasts decades. Every system we ship replaces a generator, a lead-acid bank, or diesel that would otherwise pollute the air.
Numbers that matter.
Every battery we ship replaces something dirtier, noisier, or both. Here's what our customers have built so far.
