A 51.2V 20Ah sealed LiFePO4 pack for outdoor and unmanned equipment, designed around ingress protection and mechanical robustness. It carries 1.02 kWh of usable energy and delivers 20A (40A, 10s) continuous — a full 1C draw, with headroom for the surge loads motive duty demands.
Charging at 4A brings it to full in roughly 5.5 hours. The operating window is -20~60°C on discharge and 0~45°C on charge. The pack measures 380 x 145 x 80 mm and weighs 8.5 kg.
Within our 48V range this sits between the 10.5Ah and 30Ah builds. If your runtime target is tighter than expected once we model the duty cycle, the 30Ah configuration is the usual next step; if weight or envelope is the binding constraint, the 10.5Ah build is lighter.
Ingress rating, enclosure material, connector sealing and cable gland type are specified per deployment, alongside capacity and terminal layout. Bluetooth covers on-site checks; WiFi or 4G remote monitoring is available as a custom option for unattended equipment.
What ingress rating can you achieve?
Specified per project. Tell us the exposure — spray, immersion, dust, vibration — and we design enclosure and sealing to match.
How does it handle temperature swings outdoors?
The window above covers most deployments. Beyond it we add heating or insulation at design stage.
Grade A prismatic LFP cells, generally specified with UL recognition at cell level. Every pack ships with a UN38.3 test summary and MSDS prepared for air, sea and road transport. Assembly and testing take around 7 working days. Cell supply is what sets the overall schedule: when the cells your design needs are in stock, samples ship in 12–15 working days; when they have to be sourced, allow 20–25. Tell us your target date early and we will confirm cell availability before you commit to it. Production runs 30–35 working days. There is no minimum order quantity — this is a custom design business and we quote single units, with pricing improving noticeably from 100 packs upward. LiFePO4 warranty typically runs 3–5 years, set against the discharge duty of the application; high-rate cycling shortens it.
