A 12.8V 300Ah LiFePO4 drop-in replacement built to the footprint of the lead-acid battery it replaces, so the installation itself does not change. It carries 3.84 kWh of usable energy and delivers 60A continuous, a 0.2C rating. This is a steady-load design rather than a high-rate traction pack.
Charging at 60A brings it to full in roughly 5.5 hours. The operating window is -20~75°C on discharge and 0~55°C on charge. The pack measures 520 x 238 x 220 mm and weighs 30 kg.
This is the largest 12V build we list as standard. Below it sits the 205Ah configuration; above it we move to a bespoke design rather than a catalogue starting point.
Case footprint, terminal type and position, capacity and BMS behaviour are specified so the replacement drops into the existing installation unchanged. Communication over CAN or RS485 is available where the system expects it, with Bluetooth for local monitoring.
Can we mix these with existing lead-acid batteries?
No. Mixing chemistries in one bank damages both. Replace the whole bank.
Is the weight saving significant?
Substantial, usually more than half. The exact figure depends on the lead-acid battery being replaced.
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.
