From yacht builders to solar installers — Shimu batteries power critical applications worldwide.

★★★★★

We replaced all 12 lead-acid batteries on our yacht with Shimu LiFePO4 units. Weight savings were incredible and BMS integration flawless. Three seasons in, zero issues.

Ordered 200 units for a solar farm. The Shimu team handled all export docs and had them on-site in 18 days. Actual capacity matches stated capacity — rare at this price.

★★★★★

We've tested four Chinese battery brands. Shimu is the only one that consistently meets spec. Quality control is clearly a genuine priority, not just marketing.
