What does an LTSA with BessRe cover, and what does it not?

An availability engagement covers detection, arrival and repair, and whether the part is on the shelf. Cell degradation stays with the manufacturer; Liability terms are agreed per site, in line with scope and spare-parts commitment, and access to monitoring data is a precondition. An engagement can start with a shorter initial term and extend based on operating data.

Manufacturer warranty covers the box. Someone has to answer for the site.

What an engagement looks like

Operation: availability engagement per signed agreement: certified partners on site, European spare parts, one point of accountability.

Availability and response time only

How fast we detect, arrive and repair, and whether the part is on the shelf. What we cannot control, we do not promise.

Degradation stays with the OEM

Cell chemistry is the manufacturer’s warranty. We write the boundary into the contract so a failure has one owner.

Liability with a defined edge

Liability terms are agreed per site, in line with scope and spare-parts commitment. Access to monitoring data is a precondition.

Why one year first

An engagement can start with a shorter initial term and extend based on operating data. Renewal is earned on the data. Shorter initial terms are our entry point.

What we bring together in one contract

Independent — bound to no manufacturer. When a failure has several possible owners, we say which one — in writing.

Multi-brand — accountable for whole-site availability, not one vendor’s cabinet.

China-connected — manufacturer escalation, parts channels and a Chinese-speaking front office.

Who delivers

Many manufacturers now have service teams in Europe — for their own product. When a site underperforms, the manufacturer points at the integration, the integrator at the EMS, the EMS provider at the battery, and the O&M contractor at all three. Each party covers a piece; rarely does anyone sign for the whole site.

We deliver with technology transferred from China, through certified service partners trained locally.

Partners join our network only after VCA, BA4/BA5 and ADR vetting, product training and a first-job acceptance; those who fail are removed.

The data behind the commitment

Since August 2024, Article 14 of the EU Battery Regulation gives owners access to state-of-health data; from February 2027, every industrial battery above 2 kWh carries a digital passport maintained through use. BessRe reads that data independently — which makes an availability commitment measurable.

How we charge

Standby — a monthly retainer for a committed response time. Work — one hourly rate for time on site; travel at cost. Availability engagement — per site, per year.

Frequently asked questions

What does an availability engagement actually cover?

An availability engagement per signed agreement covers how fast we detect, arrive and repair, and whether the part is on the shelf. What we cannot control, we do not promise. It comes with certified partners on site, European spare parts and one point of accountability.

How is availability measured?

We judge availability and response time on our own data. Since August 2024, Article 14 of the EU Battery Regulation gives owners access to state-of-health data, and BessRe reads that data independently, which makes an availability commitment measurable.

Who is responsible for cell degradation?

Cell chemistry is the manufacturer’s warranty. Degradation stays with the OEM, and we write the boundary into the contract so a failure has one owner.

Is there a cap on your liability?

Liability terms are agreed per site, in line with scope and spare-parts commitment. Access to monitoring data is a precondition.

What is the minimum term?

An engagement can start with a shorter initial term and extend based on operating data. Renewal is earned on the data. Shorter initial terms are our entry point.
