From EV fleets, OEM take-back and e-waste streams: packs retired at 70-80%.
A battery doesn't die.
It gets a second life.
At SLS Energy, we repurpose retired EV and e-waste batteries into modular packs that keep African businesses powered, without the Capital Expenditure, the diesel, or the waste.

Reliable power costs too much — and good batteries get scrapped long before they're spent.
Traditional backup power needs massive upfront investment, and diesel generators burn through profits on fuel and maintenance. Meanwhile most EV and industrial batteries are retired with plenty of usable capacity, then simply scrapped. We give those packs a second life.

One battery. Many lives.
Not a three-step funnel, a loop. Every pack we deploy is built to come home, be re-tested, and go back out again. That's what makes second-life storage circular, not just cheap.
