Upgraded 200A intelligent BMSOur 12V 300Ah LiFePO4 battery with integrated 200A Smart BMS delivers rock-solid power. Features bulletproof protection against overcharge, over-discharge, overcurrent, and short circuits. Its precision 0°C (32°F) low-temperature cutoff prevents damaging lithium plating in freezing conditions. With massive 300Ah capacity and intelligent safeguards, enjoy every appliance worry-free and unleash your adventure.
4S4P Flexible ExpansionCompact and powerful, this LiFePO4 battery weighs just a mere 1/3 of comparable lead-acid batteries! Each 12V 300Ah lithium battery adopts a standardized design, supporting a 4S4P parallel connection expansion method. This means you can start with a single battery and gradually add more according to your actual needs, effortlessly building up to a 48V / 1200Ah large-capacity energy storage system. This solution is exceptionally well-suited for solar farms / industrial mobile power stations, enabling your RV, marine vessel, camper, or off-grid cabin to scale seamlessly alongside growing energy demands.
All-Weather Safety Protection Built-in intelligent low-temperature protection automatically pauses discharge below -4°F and resumes charging above 32°F, ensuring reliable startups on icy mornings or hot summer afternoons.
Seven layers of intelligent safeguards: BMS rigorously defends against overcharging, over-discharging, overcurrent, short circuits, and high temperatures.
