Why choose us
There are plenty of Chinese lithium battery suppliers. The difference usually shows up not at the pricing stage but on the second shipment — when someone has to solve a problem rather than close a sale.
A factory, not a middleman
We manufacture in-house: 2 production bases, 10 automated lines, 10,000 m² of dust-free workshops. You buy at factory price with no trader markup and speak directly to our engineers.
100% in-house BMS
Hardware and firmware are developed by our own team. CAN / RS485 support, compatibility with Deye, Growatt, GoodWe, SMA and INVT inverters. Protection algorithms are tuned to your project.
Warehouse in Russia — stock nearby
One of our 9 overseas warehouses is in Russia. Fast-moving SKUs can ship from local stock instead of waiting 40+ days by sea. Seasonal top-ups take days, not months.
Customs paperwork in order
CE, UN38.3, RoHS, UL, IEC 62133, test reports, MSDS and shipping documents are supplied as a package. We help prepare the file for EAEU requirements.
Your brand on our product
Full white-label: logo, enclosure colour, capacity, connectors, packaging, Russian-language manual. MOQ is negotiable — we start with a trial batch.
Support after shipment
A dedicated engineer, 24-hour response, drawings and firmware, spare parts, claim analysis from photos and BMS logs. Battery warranty — 5 years.
Factory vs. middleman
| Who is responsible for defects | GRNOE: We do. Analysis from BMS logs and photos; the outcome is replacement or compensation. A middleman forwards the question to a factory and waits alongside you. |
|---|---|
| Can the design be changed | GRNOE: Yes: capacity, connectors, enclosure, BMS firmware, packaging. Only what the contract factory already has on the shelf. |
| Where the price comes from | GRNOE: Production cost plus our margin. One markup layer. Factory price plus trader markup. Two layers at least. |
| What about batch consistency | GRNOE: One line, one cell-grading method, one test protocol. Batches may come from different factories — you find out after the fact. |
