Get a complete battery setup in one order. This combo pairs the B2 Audio 44AH LiFePO4 battery with short brass SAE top post adapters and a pair of Big Jeff Audio 4 lug-style terminals, so you can run several power and ground connections from one clean top post setup.
The B2 Audio 44AH supports up to 5,000 watts of continuous music power and 10,000 watts of burst power, with 594 watt-hours of reserve energy to help reduce voltage drop when your amps pull hard. It’s lighter than a traditional AGM battery, charges fast, and is maintenance free.
The short brass adapters bolt directly to the battery’s M6 terminals with the included stainless steel screws and give you standard clamp-style SAE posts. From there, the polished aluminum Big Jeff Audio terminals clamp on, each with four lug-style connections and 3/8 inch mounting holes for compatible ring terminals.
Requires a lithium-compatible battery charger. Pair it with a properly upgraded charging system to keep your setup playing strong.
Features:
