We'd been through three different lead-acid supliers in two years before we finally switched, and honestly, the maintenance alone was killing us—this 48V 100Ah-300Ah LiFePO4 setup basically solved that overnight, though we had to confirm teh lead time was 30 days or so for the custom terminal configuration we needed.
Cycle life hits ≥2000 cycles at 80% DoD, which is better than most AGM we've tested, and the built-in BMS handles the usual overcharge and thermal stuff without any fuss; we've got them in a solar array that sees -20°C discharge temps in winter, and they've held up fine, though we usually keep them above 0°C for charging (check the spec sheet).
Energy efficieny is ≥95%, so you're not losing much to heat, and the self-discharge rate of <3% per month means our company can leave them sitting for weeks during low sun months without a top-up—most buyers go with the 200Ah for residential systems, but we've seen telecom guys grab the 50Ah for backup.
What you get when ordering is a unit that weighs about 12kg per 100Ah at 12.8V, but the 48V version scales differently—roughly 35kg for the 100Ah—and the M8 bolts are standdard, though we had to request a custom terminal for a tight enclosure once, and they handled it without a markup.
Anyway, it's not suited for high-rate discharge like EV acceleration, but for solar storage or UPS duty, it's pretty much a set-and-forget solution; the 10-year defects, but we've only had one claim in three years, and that was a BMS firmware issue on an early batch.
For high-capacity units like the 300Ah, we typically require a MOQ of 10 units for factory-direct pricing. Smaller quantities can be arranged but at a slightly higher per-unit cost.
Standard lead time for custom orders is about 15-20 working days after order confirmation. If you need it faster, we can rush production for bulk orders.
Yes, we include UN38.3 test reports and MSDS with every shipment. We also handle all necessary documentation for air or sea freight.
Sure, we can customize the terminals to match your system. Just let us know what type you need when placing a bulk order.
Store it in a cool, dry place between -10°C and 35°C. The self-discharge rate is under 3% per month, so it can sit for up to 6 months without charging, but we recommend a top-up every 3 months.
