OPzS Series Tubular Flooded
Lowest cost per cycle for large-scale stationary storage
OPzS series uses tubular positive plates in a flooded (vented) design — the classic workhorse for large stationary installations.
With the lowest cost per ampere-hour at high capacity and a 20-year design life, OPzS remains the standard choice for utility-scale solar, wind and substation projects where regular maintenance is available.

FAQ
What is OPzS Series Tubular Flooded used for?
OPzS Series Tubular Flooded is built for Solar & Wind Storage, Telecom & Base Station, UPS & Data Center. If your load profile or cabinet size is unusual, send us the numbers — we will match the model, or quote a custom build.
What service life can I expect?
Design / cycle life: 20 years (float) · 1500+ @60% DOD. Real-world life depends on temperature, depth of discharge and charging quality — we size the bank for your target years, not just the datasheet number.
What is the MOQ?
Standard models start at 50–100 pieces per model, and several models can be mixed in one container. For OEM / ODM with your own labels or colours, the MOQ is agreed per project.
What is the lead time?
Standard models ship in 15–25 days after deposit. Custom OEM orders usually take 30–45 days including label and packaging approval. Sea freight adds 20–35 days depending on destination.
Do you support OEM / ODM?
Yes — custom labels, colours, terminal types, carton printing and manuals. We also develop to your target capacity or dimensions. An NDA can be signed before you share drawings.
What certifications do you have, and can batteries be shipped?
CE and RoHS for the EU market, plus MSDS and UN38.3 with the documentation required for sea and air transport. Test reports can be supplied with the quotation.
