BigVell Lithium 40Ah LTO Lithium 12v battery. Its called The Beast 40 for a reason. Conservative Over 400a and over 4000 watts stand alone (No Alternator). When we say the word Over we really mean OVER. No funny stuff going on here. Nothing but good American built batteries using high grade copper internals with top grade 7 spot customs terminals made by Toolmaker. That 4000 watts is not a burp or burst... Its nothing but pure amperage pulled from the battery for 15 seconds. Peak Power your looking at over 8000 watts!! Nominal voltage is 13.8 max voltage 15.9 Minimum 11.5 volts. -15 degrees minimum operating temperature 150 degrees  maximum operating temperature.

We ran this battery in our demo car for almost an entire season on a stock alternator. Just 2 40Ah batteries on a system 16,000 watts capable. Tons of hard hitting demos with power to spare.

Equal to 4 100Ah AGM batteries. Height 9'' Width 8.75'' Depth 6'' Height with terminals 10 1/16'' (inches)
