We exist so your product never waits on its battery.
A team of power-systems engineers turning ambitious products into reliable, certified, production-ready reality.
It started with one frustrating battery.
Our founders shipped a brilliant product crippled by an off-the-shelf battery that overheated, under-delivered and failed certification twice. No manufacturer treated the battery as a serious engineering problem.
So they built one. Today JRH engineers hundreds of programs across mobility, medical, robotics and energy — and still treats every project like that first one.
The standards behind every cell.
Safety First
Uncompromising safety engineering on every chemistry, cell and connection.
Engineering Rigor
Decisions driven by simulation and measured data, never guesswork.
Radical Transparency
Open test data, BOMs and traceability so you know what powers your product.
True Partnership
One accountable team from first prototype through global volume.
Relentless Quality
A 99% QC pass rate held through inline inspection at every stage.
Sustainable Design
Second-life planning and responsible sourcing built into every program.
