If you're setting up a weekend cabin or a small off-grid workshop, this 28kg battery is actually manageable to carry down a narrow staircase—it's not one of those 50kg monsters you dread moving. We've had buyers use it for solar backup in remote telecom stations too, and the 2.5kWh capasity handles a few hours of lights and a fridge without breaking a sweat.
It runs on LiFePO4 chemistry with 6000 cycles, so you're looking at roughly 10 years before it starts to fade, give or take how deep you drain it each time. The voltge range sits between 22.4V and 29.2V, and it's a standerd 0.5C discharge—1C if you push it, but that'll shorten its life a bit. Dimensions are 689 by 495 by 162mm, and it come with RS485 and CAN ports for talking to your inverter.
What it's not great for is high-current stuff like starting a big water pump—the BMS will trip on overcurrent if you exceed 1C for more than a few seconds. But for steady solar storage, it's better than lead-acid in cold weather, working down to -30°C (though performnce drops noticeably below freezing). Most people keep it in a ventilated garage or basement; IP20 rating means dust can get in, so don't mount it where sawdust flies around.
Anyway, we usually have these in stock, but confirm lead time if you need a custom terminal orientation or a specific firmware flash—that adds 20 days or so. MOQ is one unit, and we'll send teh COA and UN38.3 paperwork with the shipment.
MOQ for standard units is 10 pieces, but we can discuss lower quantities for samples. Yes, we offer custom color and label branding — just send us your design specs and we'll adjust the quote accordingly.
Typical lead time is 20–25 working days for a run of 50 units after order confirmation and deposit. If you need faster delivery, let us know and we can check our current stock.
Absolutely — we can share the CE certificate and UN38.3 test report right away. Just reach out to our sales team and they'll email you the documents.
Yes, the max continuous discharge is 100A (1C), but keep in mind standard discharge is 50A (0.5C) for optimal cycle life. Running at 1C will work, but it'll generate more heat and reduce lifespan.
We include both RS485 and CAN ports on the BMS, but cables are not bundled by default — you can add them as an accessory. The RS485 uses Modbus RTU protocol, and CAN uses CANopen. We'll provide the protocol docs upon request.
