WattCycle 12V 100Ah LiFePO4 Lithium Battery with Bluetooth, BCI Group 24, 100A Smart BMS, 15000 Cycles, 10-Year Life, Perfect for Marine Trolling Motor RV (2 Packs)

• 🍃-Small Size, Large Capacity: The mini WattCycle 12V 100Ah LiFePO4 Lithium Battery cuts weight by 11% and volume by 39% compared to the previous generation, with an energy density of 63wh/lbs. This means it delivers full 100Ah power without taking up excess space—perfect for portable setups like marine dinghies or RV backup power.
• 🍃-More Compact: Weighing only 20.94lbs and measuring 9*5.4*8.2 inches, this means it's easier to carry. With the same battery storage space, you can accommodate more batteries, providing you with more power for your outings.
• 🍃-Bluetooth-Enabled Battery Monitoring: After installing the WattCycle App, you can name your battery (ideal for 4S4P setups) and check real-time status: voltage, current, temperature, and alarms. This lets you track power levels remotely—no need to open RV storage or climb into boat battery compartments to check on your battery.
• 🍃-Long-Lasting EV Grade A+ Cells: With EV Grade A+ cells, this battery offers a 10-year lifespan and up to 15,000 deep cycles—enough to power your marine or RV needs for over a decade. It also supports 4S4P expansion, reaching 20.48kWh total capacity to run large appliances like RV fridges or marine trolling motors for hours.
• 🍃-Cold-Resistant Operation: It functions from -4℉ to 158℉ (-20℃ to 70℃) and auto-stops charging below 32℉ (0℃) to prevent cell damage. When temps rise above 41℉ (5℃), it resumes charging automatically—so you get consistent power for fall camping or early-morning boat trips.
• 🍃-100A BMS for Safe Expansion: The built-in 100A BMS protects against overcharge, deep discharge, overload, and short circuits—critical for 4S4P setups. It also balances cells to ensure even performance across all batteries, avoiding uneven wear that can reduce the entire system’s lifespan.
• 🍃-Reliable Warranty & Support: This battery comes with a 5-year warranty. For help with 4S4P setup, App connectivity, or troubleshooting, contact our team via Amazon (24-hour response) or official email. Our experts can guide you through expanding your power system or fixing issues quickly.
