B2 Audio 44AH 12V 5000W LiFePO4 Battery + XS Power Li1208 Charger + SAE Posts

• BATTERY, CHARGER, AND POSTS IN ONE ORDER: You get the B2 Audio 44AH LiFePO4 battery, an XS Power Li1208 lithium charger, and a pair of short SAE brass posts, so you’re covered from install to maintenance.
• USE STANDARD CLAMP TERMINALS: The short SAE posts thread into the battery terminals and convert them to regular automotive top posts, so you can connect with clamp-style terminals instead of ring terminals.
• 44AH OF RESERVE POWER: With 594 watt hours of stored energy, the battery helps keep voltage steadier so your amps stay consistent through heavy bass notes.
• 5,000W CONTINUOUS MUSIC POWER: Rated for 5,000 watts of continuous music power and 10,000 watts max, with up to 4,100 amps of output current for high-powered setups.
• CHARGES FROM A STANDARD OUTLET: The charger runs on 110 to 230 VAC and stops at 14.4V, so you can plug in at home or the shop and keep the battery topped off between uses.

B2 Audio 44AH 12V 5000W LiFePO4 Battery + XS Power Li1208 Charger + SAE Posts

This Listing Includes:

• (1) B2 Audio 44AH 12V Lithium Iron Phosphate (LiFePO4) Battery

The B2 Audio 44AH LiFePO4 battery gives your system the power reserve to keep up with the bass, helping cut down voltage drop when your amps pull the hardest. Since a lithium battery needs a lithium-compatible charger, this combo includes the XS Power Li1208, an 8 amp charger with a 14.4V cutoff, so you can top it off at home or in the shop between car meets or when the car’s been sitting. The short SAE brass posts turn the battery’s terminals into standard automotive top posts, so you can connect with regular clamp-style terminals. It works for daily drivers, competition builds, and demo vehicles alike.

Features:

• For bigger systems, pair the battery with an upgraded charging system so it stays charged while you drive


• Maintenance free, with high shock resistance for daily driving and competition use


• Positive post is slightly larger than the negative (0.75" vs 0.69" diameter), following standard SAE sizing so clamps only fit the correct side


• Brass post adapters with stainless steel screws and split lock washers to help keep the connection tight


• Charger comes with a 5.0' (1.5 m) AWG 16 AC input cable and a 3.9' (1.19 m) AWG 10 DC output cable


• Fuse protected AC input on the charger


• Charger weighs 2.2 lbs (1 kg), easy to keep in the trunk or on a shop shelf


• The Li1208 also charges Yinglong LTO cells and Headway lithium cells


• Battery mounting hardware, power wire, and clamp-style battery terminals are not included
