WattCycle 12V 100Ah LiFePO4 Lithium Battery, 12V Battery with 110A Smart BMS, Group 31 Size, 15000+ Cycle Life, Low-Temperature Protection, for RV, Marine, Solar, Home Backup

Features

• Group 31 Size, Higher Usable EnergyDesigned as a Group 31 form-factor lithium battery, this 12V 100Ah LiFePO unit delivers 1280Wh of usable energy with reduced weight and stable voltage output. Compared with traditional lead-acid batteries, it supports longer runtimes and more efficient energy use for RVs, marine electronics, trolling motors, and off-grid systems.
• 110A Smart BMS for Stable Power OutputEquipped with an upgraded 110A intelligent Battery Management System, supporting up to 110A continuous discharge. The BMS helps manage overcharge, over-discharge, overcurrent, short circuit, and temperature-related conditions, ensuring reliable operation under both steady and high-demand loads.
• EV-Grade A+ Cells & Long Service LifeConstructed with EV-grade A+ prismatic lithium cells, engineered for extended cycle performance of approximately 5,000 to 15,000 cycles under recommended usage. Provides consistent 1280Wh energy delivery with low maintenance requirements and reduced replacement frequency over time.
• Durable Housing with Temperature ProtectionFeatures an internal metal reinforcement and an IP65-rated enclosure to enhance resistance against vibration, dust, and moisture. Integrated low-temperature protection temporarily limits charging below 32F and discharging below 4F to help protect battery performance in cold environments.
• Expandable System & Charging CompatibilitySupports up to 1C charging and is compatible with LiFePO chargers, solar controllers, and generators. Allows system expansion up to 4S4P for increased capacity. Certified to IEC, CE, FCC, RoHS, UN38.3, and Class 9 standards, and backed by responsive after-sales support with a 5+2-year warranty.
