We've got stock on the 12.8V and 48V models right now, the 51.2V usually takes about 20 days or so to ship out after order — lead time depends on your capacity choice, obviously, but our company can push it if you're in a bind.
What really makes these worth buying is the cycle life, we're seeing well over 4000 cycles at 80% depth of discharge, and that's not just a spec sheet number; we've tested a few batches ourselves and they hold up better than most LFP packs we've handled, especially in solar setups where you're cycling daily.
The built-in BMS covers overcharge, overdischarge, and short circuit, and you can get RS485 or CAN communication on the 48V and 51.2V units — basically plug-and-play for most inverter brands we've seen, though we don't have a full compatiblity list for every model.
For the 12.8V series, max continuous discharge is 100A with a 200A peak for 5 seconds, which is fine for most residential loads, but if you're running heavy inverters (like 5kW or more), we'd suggest stepping up to the 48V or 51.2V for better headroom.
One thing to watch — these aren't great for high-temperture environments beyond 60°C discharge, so if your site hits that regularly, you'll want active cooling or a different chemistry; we usually keep them in ABS+PC fireproof cases, but that doesn't solve ambient heat.
Also, terminal is M8 bolt, so make sure your cables are pre-crimped with the right lugs — we can include them if you let us know, but we don't always have them in every kit, and cold chain shippng isn't needed since they're dry cells, just standdard freight with proper packaging.
You can choose 12.8V, 48V, or 51.2V nominal voltage, and capacity from 50Ah up to 300Ah—fully customizable based on your needs.
MOQ typically starts at 50 units per model, but we can discuss smaller trial orders for new partnerships. Just reach out with your specific requirements.
Lead time is usually 15-25 working days after order confirmation and deposit, depending on current production load. Custom capacities might take a bit longer.
Yes, all models are certified with CE, RoHS, ISO9001, and UN38.3. We can provide the certificates upon request for your compliance needs.
Absolutely. The built-in BMS supports optional RS485 or CAN communication, so you can choose the protocol that works with your inverter or monitoring system.
