Lithium / SLIP40AH

Todays amplification power has grown to the extreme. With 5.000 watts being common for the substage, the total power of systems can easily peak at 10.000 watts.
Our M-series amplifiers can even provide you with 14.000 watts at ordinary alternator voltage. It takes power to make power, premium wire cable hooked up to a large & heavy battery bank is a must. 100 kgs of added weight in batteries has become the standard.

Not to mention those with several power hungry amplifiers have easily added 300 kgs / 660 lbs to play it safe. In addition comes the weight of the amplifiers, speakers & enclosures.
The SLIP40AH lithium battery will drastically decrease the weight of your batteries, increase the overall performance and even take up less footprint. Each SLIP40AH has the equivalent peak performance to 3 mid-sized premium agm batteries. The average weight saved can easily be 90 kgs / 200 lbs.

Another benefit is the saved cost of alternators. A stock alternator is sufficient for a single lithium battery, but we have made the SLIP40AH capable of peak charges up to 250 A. As long as the operation temperature is not exceeded (-4° ~ 140° F / -20° ~ 60° C), the battery can be used in the engine bay.

During the R&D done in the US, current draws of 800 A from the SLIP40AH provided a better spl score compared to a bank of 3 AGM batteries, in addition the lithium rebounced within 30 seconds to floating voltage, while the agm kept decreasing from each test.

The SLIP40AH uses a casing where no assembly is required, making it faster and easier to replace a stock or upgraded battery bank. Safe charging is handled by a “BMS” Battery Management System & cells are balanced. Shipping is done by a certified hazmat shipper and the SLIP40AH complies with the UN3480 shipping standard.
