BigBattery 36V 2X RAPTOR 2 Lithium Battery KIT – 7.68kWh High-Performance LiFePO₄ Power
Maximize your range, power, and performance with the BigBattery 36V 2X RAPTOR 2 Lithium Battery KIT, delivering an impressive 7.68kWh of reliable LiFePO₄ energy. Whether you're powering a golf cart, utility vehicle, industrial machine, or pallet jack, this dual-battery system is the ultimate upgrade from outdated lead-acid setups—providing more energy, faster acceleration, and longer runtimes in a lightweight, compact design.
Each RAPTOR 2 battery is built with Tier 1 lithium iron phosphate (LiFePO₄) cells, the safest and most stable chemistry on the market. Paired with an advanced Battery Management System (BMS) and automatic cell balancing, this system ensures long-lasting performance and full protection from over-voltage, under-voltage, over-current, and temperature extremes. Plus, the IP65-rated casing offers superior resistance to water, dust, and vibration—perfect for work and play in tough environments.
Stay fully informed with the included Battery Capacity Meter (SOC) and RS485 communication protocols, providing real-time monitoring at a glance. This complete kit also includes a 36V 25A lithium charger and parallel busbar, making it a true plug-and-play solution that installs easily in most battery trays without modification.
