Sanyuan Lithium 3.7V High-Performance Automotive Starting Battery
High-capacity 6.2AH lithium core with 70C discharge rate delivers instant, powerful cranking for heavy-duty vehicles and welding machines. Premium-grade lithium iron phosphate (LiFePO4) ensures ultra-stable voltage output, extended cycle life (2000+ charges), and extreme cold/heat resistance (-20°C to 60°C). Precision laser-welded terminals and reinforced ABS casing prevent corrosion, vibration damage, and short circuits—ideal for trucks, boats, and industrial equipment. 30% lighter than lead-acid batteries, maintenance-free design with built-in BMS for overcharge/overheat protection. Global wholesale pricing—bulk orders available with fast logistics. Direct factory supply guarantees lowest cost.
