Ionic Lithium 36V 75Ah | LiFePO4 Deep Cycle Battery Bluetooth

Product Description Ionic 36V Lithium Battery: Deep Cycle Lithium Battery IC-36V75-EP 36V Lithium Battery Management System: World-Class Safety Features The Ionic Deep Cycle IC-36V75-EP delivers 36 volts and a 75Ah capacity — 50% more usable power than the 50Ah — making it the strongest single-battery choice for 36V trolling motors, marine applications, and other demanding deep cycle systems. With 2,880Wh of total energy, you can run longer and harder without worrying about running out of juice. This Ionic lithium iron phosphate battery (LiFePO4 — not a lithium ion battery) features an internal microprocessor-controlled advanced BMS that continuously monitors voltage, current, and temperature during charging and discharging. It protects your battery, maximizes its life, and automatically prevents charging if conditions are unsafe. Run Ionic batteries in parallel for unlimited range. Built to Last Longer, With Twice the Power The Ionic 36V 75Ah has a cycle life of 3,000 cycles — roughly ten years of real-world use — and a usable capacity of 99% compared to 50–60% for traditional lead-acid batteries. The ABS enclosure carries an IP65 rating, meaning it’s built to handle water exposure on the water. Operating temperature range: -4°F to 140°F (-20°C to 60°C) for discharge, and 32°F to 113°F (0°C to 45°C) for charging. The battery automatically detects if it’s too cold to accept a charge and will not charge until conditions are safe. World-Class Battery Management System Protects Against: Overcharging (BMS charge voltage cut-off: 45.6V) Over-discharge (BMS discharge voltage cut-off: 30V) Extreme temperatures (high temperature cut-off: 149°F / 65°C) Short circuits (protection response: 200–600 µs) Excessive discharge current (BMS discharge current cut-off: 650A at 30ms) Mobile Bluetooth Monitoring — Check Your Battery Status With a Tap: Power Temperature Voltage Battery health status Remaining charge time Current draw Outperforms Traditional Lead-Acid Batteries: Half the weight Lasts 2–4x longer Zero maintenance 200% power 500% faster charging 11-Year Warranty IP65 water protection 99% Depth of Discharge Less than 3% monthly self-discharge (vs. ~30% for lead-acid) Fast and free shipping in the U.S. Eco-friendly design Consistent power delivery Best Weight-to-Power Ratio on the Market At 45.2 lbs (20.5 kg) and 13.2 × 6.9 × 9.6 inches (334 × 176 × 245 mm), the 36V 75Ah packs 2,880Wh into a ABS enclosure that installs in any direction thanks to the 3/8-UNC terminals. That flexibility is something fixed lead-acid batteries simply can’t offer. Real-Time Battery Monitor Download the Ionic Blue Batteries app on iPhone or Android to monitor power, voltage, temperature, remaining charge time, and battery health status in real time — right from your phone while you’re on the water.
