XS Power 12V Lithium PowerCell – Extreme Audio Performance
This high-performance 12-Volt lithium battery delivers up to 20,000 watts of peak power, ensuring your audio system hits hard with no compromise. With a massive 90Ah capacity and 14.8V max voltage, it provides extended runtime and stable performance under heavy loads. Weighing only 25 lbs., it’s easy to install in-cabin and comes ready with M6 hardware, an active balancer for consistent cell voltage, and a pre-assembled steel/Plexiglass case with four positive/negative terminals for DIY battery bank expansion. Designed for serious audio enthusiasts, it requires a compatible lithium charger (Li1208, Li1215, or Li1225) to maintain peak performance.
Frequently Asked Questions (FAQ)
- • Why doesn't the XMAX 90-DIY have enough connection points for my setup?
Some users have noted that the four included terminals can become limiting in complex high-power systems. If you need additional connections, XS Power offers compatible terminal-block options for expanding the wiring setup.
- • Can the XMAX 90-DIY handle multiple high-powered amplifiers?
Yes, owners have reported using the battery with multiple powerful amplifiers and large subwoofer systems. Proper alternator capacity, cable sizing, grounding, and charging voltage are still essential for maintaining stable performance.
- • What charger should I use with the XMAX 90-DIY?
The XMAX 90-DIY requires a lithium-compatible charger. XS Power specifically recommends its Li1208, Li1215, or Li1225 chargers for the xMax battery series.
- • Why does my XMAX 90-DIY arrive with a lower resting voltage than expected?
A newly delivered battery may not always show the exact voltage a customer expects. One owner reported receiving the battery at 13.1V and charging it with an XS Power lithium charger before installation. Checking the battery voltage and charging it correctly before putting it under heavy load is a sensible first step.
- • Can shipping damage affect my XMAX 90-DIY?
Packaging and transportation have been mentioned in customer feedback. One owner reported a surface dent on the bottom of the battery, while another said the shipping box arrived heavily beaten. Inspect the case carefully when the battery arrives before installing it.
- • Will the XMAX 90-DIY fit my factory battery tray?
The battery is designed for in-cabin installations, but its dimensions and terminal arrangement may differ from a factory battery. Measure your tray, mounting area, cable clearance, and hold-down arrangement before assuming it will be a direct fit.
- • Why does my XMAX 90-DIY need a different charging setup than my old AGM?
The XMAX 90-DIY uses lithium chemistry, so it requires charging equipment appropriate for the battery rather than simply treating it like a conventional AGM battery. Using the recommended lithium charger helps maintain the correct charging profile.
- • Can I separate the XMAX 90-DIY from my starting battery?
Yes, users have reported running the XMAX 90-DIY as a dedicated audio-system battery while separating it from the vehicle's AGM starting battery with an isolator. This can be useful when protecting the starting battery from heavy audio-system loads.
- • Is the XMAX 90-DIY suitable for a large bass system?
The battery is built for demanding in-car audio applications, and owners have reported running substantial subwoofer and amplifier systems with it. One owner reported using it with four 12-inch subwoofers and two high-output amplifiers.
- • Why doesn't my XMAX 90-DIY look exactly like the product photos?
A customer review specifically reported that the plexiglass panel did not have the etched XS Power lettering shown in the product imagery. If appearance matters to your installation, it is worth checking the current product version rather than relying solely on older promotional photos.
