About
We build the packs and hold the stock — that is the whole offer
圣拓(湖南)能源技术有限公司 / Sento (Hunan) Energy Technology Co., Ltd. makes and sells LiFePO4 battery
packs: household storage, small commercial storage and low-speed traction systems. Cells and
packs are assembled to order, tested, and put on the shelf in the EU before the order exists.
What that means in practice
Two businesses in one
A pack builder. We buy grade-A cells by the container, assemble and test 16S packs,
and ship them under our own documentation. Configuration is the customer’s choice: capacity,
case, BMS, connector, inverter pairing.
An EU stock point. We keep the fast-moving models in Germany and Poland. That is what
turns a 45-day import into a 3–7 day delivery, and it is the reason most of our European
customers came to us in the first place.
Quality
How the packs are built
- Cells selected and matchedGrade-A cells, sorted by internal resistance
within the batch before assembly. - Assembly and torquingBusbars torqued and marked; insulation and
spacing checked before the cover goes on. - BMS configurationProtection thresholds, communication protocol and
inverter pairing set for the model, not left at default. - Charge / discharge testEach pack cycled before packing; the record
goes out with the shipment. - Packing for transportUN-certified cartons, wooden crate and pallet for
cabinet models.
Export & support
China HQ, Europe-facing
Export documentation, EU warehouse intake and after-sales all sit with the same team you
write to — no separate department to chase.
Languages
English, Spanish and Chinese. Ukrainian and Polish on request with
our local partners.
Customisation
Case colour, connector type, BMS brand, capacity and label
printing for your own brand.
Warranty
10 years on cells under manufacturer terms. Spares and replacements
are held with the EU stock, so a claim does not wait for a container.
