We can dial in the votage and capacity to your exact setup—2V to 12V, 30AH all the way up to 3000AH—so you're not stuck with off-the-shelf sizes that don't fit your rack or your load profile.
Most buyers go with teh 2V 3000Ah for solar farms, but we've also shipped these to telecom sites and marine ops where the deep-cycle recovery is actually better than what you get form flooded cells.
The gel electrolyte means you don't worry about acid spills if ABS case gets cracked, and self-discharge stays under 3% per month (check lead time for custom builds—usually 4-6 weeks).
Cycle life is 2000+ at 25°C, but if you're cycling hard in a UPS with frequent dips, you'll still get solid years before replacement. It's not suited for high-rate discharge application like engine starting, anyway.
Terminals are M8, dimnesions roughly 275x210x827mm for the 3000Ah variant, and we include COA with every batch. Weight is about 106.5kg give or take—so plan your handling accordingly.
MOQ is typically 10 units for custom specs, but our company can flex on that if you're a repeat buyer or bundling with other gear from our catalog.
Our MOQ is 10 units for the 2V OPzV series, but we can be flexible on larger capacity variants if you're stocking for a solar project.
Lead time is typically 15-20 working days after order confirmation and deposit, depending on the total AH capacity ordered.
Yes, we include copies of CE, RoHS, and ISO9001 certificates in the shipping documents. You can also request them in advance for your tender.
The M8 terminal is our default, but we can swap to M6 or M10 if you need it. Just confirm when placing the order.
Keep them in a cool, dry place below 25°C. Since the self-discharge is under 3% per month, you can store them for up to 6 months without charging, but we recommend a refresh charge every 3 months.
