Product Advantages & Applications
a.-40°C Extreme Cold Start Discharges reliably down to -40°C. Built-in electrical heating ensures instant ignition in Arctic winters where lead-acid batteries simply fail.
b. 1020A CCA — Massive Cranking Power 1020A Cold Cranking Amps (tested at -18°C) delivers explosive starting current for heavy-duty diesel engines, generators, and construction machinery.
c. 40,000 Start Cycles — 10× Longer Life Rated for 40,000 starting cycles vs. 3,000–5,000 for lead-acid. Drastically reduces replacement cost for fleet operators.
d. IP67 Waterproof — Passed vibration, mechanical shock, crush, salt spray, thermal shock & immersion tests. No fire. No explosion. No leakage.
e. Only 22 kg —60% Lighter Than Lead-Acid Compact L480×W215×H220mm footprint with equivalent or superior power output.
f. Smart BMS + Bluetooth/4G Monitoring Real-time remote monitoring of voltage, temperature & SOC via Bluetooth or 4G. Prevents over-charge, over-discharge & short-circuit automatically.
