If you're buying in bulk, the pricing really starts to work in your favor — samples run about one and a half times the per-unit cost, mid-tier orders of 50 units or so drop that by roughly 20%, and full container loads give you the best margin, usually around 35% off the sample price.
What it does in practice is sit there for decades without complaining — we've had customers install these in off-grid solar arrays and basically forget about them for 15 years, checking voltge once a quarter and that's it.
The 2V cells come in capacities form 200Ah up to 3000Ah, and that 20-year design life is under floating charge at 25°C — standby voltage should sit between 2.27V and 2.30V, cycle use needs 2.43V to 2.47V, and you'll want to keep the charging ratio at 0.2C for best results.
Most buyers go with teh 1000Ah cell for utility-scale solar farms because of that it's easier to handle than the 3000Ah monsters — those weigh about 180 kilos each, give or take, and you'll need a forklift for insallation.
These aren't suited for high-rate discharge applications like UPS systems that need to dump power in minutes — they're designed for slow, steady discharge over 10 hours or more, which is perfect for solar storage but not for emergency backup.
Lead time is usually 4 to 6 weeks for bulk orders, but we keep the 500Ah and 1000Ah models in stock for mid-tier quantities (check lead time for the 3000Ah — those are made to order).
Our MOQ for bulk wholesale is 50 units, but we can be flexible depending on the specific model and stock availability. Just reach out to us with your required quantity and we'll work out the details.
Lead time is usually 15-20 working days after order confirmation and deposit, depending on the capacity and quantity. For urgent orders, we can sometimes expedite production—just let us know your timeline.
Yes, all our 2V solar batteries are ISO and CE certified, and we provide full test reports including capacity and cycle life data. We can also supply a certificate of origin if needed.
We offer some customization on terminal types—like copper or lead-plated options—but the nominal voltage and design specs are fixed at 2V for this series. Let us know your specific requirement and we'll see what we can do.
Store them in a cool, dry place at 25°C ± 5°C, and keep them at standby voltage (2.27V~2.30V) if not in use. Under proper conditions, they can sit for up to 6 months without needing a recharge.
