🍃【Group 31 Dual Power Upgrade】 The WattCycle 12V 100Ah 110A BMS LiFePO₄ Battery 2-pack is designed as a Group 31–compatible drop-in option for replacing aging lead-acid banks, offering matching dimensions, lighter weight, and increased usable capacity. With a combined 2560Wh capacity and 2816W rated power output, this pair supports extended runtime and steady efficiency for RV house systems, trolling motors, marine setups, off-grid cabins, and solar storage. 🍃【Enhanced Dual 110A Smart BMS】 Each battery includes an upgraded 110A Smart BMS supporting 110A continuous discharge with protection for overcharge, over-discharge, overcurrent, short-circuit, and temperature conditions. The dual-pack configuration is designed to provide dependable and stable power delivery during higher loads or longer operation periods for RV, marine, and off-grid equipment. 🍃【EV-Grade Cells & Long Life Pair】 Built with EV-grade A+ prismatic cells, the 2-pack is rated for 5,000–15,000 cycles and long service life. Together, they offer a 2560Wh energy reserve with stable voltage output and a maintenance-free structure, helping reduce the frequency of replacements and associated long-term operating costs compared with common lead-acid solutions. 🍃【Rugged Dual IP65 Protection】 Both units include reinforced internal metal frames and IP65-rated housings for vibration resistance, salt-spray durability, and long-term structural stability. Low-temperature cutoff helps manage discharge below –4°F and charge below 32°F, restoring normal operation above 41°F for cold-weather use in boats, RVs, and off-grid power systems. 🍃【Smart Expansion & Flexible Charging】 The 2-pack supports 1C charging, solar integration, generator charging, and LFP chargers. It can be configured up to 4S4P for expanded energy storage up to 20.48kWh. Certifications include IEC, RoHS, CE, FCC, UN38.3, and Class 9, and it comes with responsive delivery options, a 5+2-year warranty, Bluetooth monitoring, meters, and technical support. The WattCycle 12V 100Ah 110A BMS LiFePO₄ 2-Pack delivers 2560Wh total energy with upgraded 110A protection for safe, high-load performance. Built with EV-grade A+ cells, both batteries provide 5,000–15,000 cycles and 10+ years of life—offering 2× usable energy and 10× lifespan over lead-acid. The IP65 metal-reinforced design withstands vibration, moisture, and harsh climates, with low-temperature cutoff for winter safety. Supports 1C fast charging, solar/generator input, and 4S4P expansion for RVs, marine, off-grid, and home energy systems.
