Sunway 25.6V 200Ah LiFePO4 Battery
200Ah / 25.6V · 5,120Wh — real storage for RV, marine, off-grid, and solar backup
>2,000 cycle life — designed to outlast lead-acid by a wide margin
Maintenance-free LiFePO4 — no watering, no acid leakage, no routine voltage checks
IP65 protection — dust-tight and water-resistant for demanding environments
38kg — easier to handle and install than comparable lead-acid capacity
Wide temperature range — reliable operation from -20°C to 60°C
M8 terminals · 522×269×219mm — standard footprint for drop-in replacement
One-liner： Replace the lead-acid treadmill with 5kWh of maintenance-free LiFePO4 storage—lighter, longer-lasting, and IP65 protected for RV, marine, and off-grid use.
