XS Power D3400 – Reliable Main Battery for Moderate Systems
Brand: XS Power
The D3400 is a solid choice if you need a reliable main battery for a system in the 1,500–2,000 watt range without spending a fortune.
The XS Power D3400 is a 12V AGM battery with 3,300 max amps, 65 Ah, and 1,000 cranking amps (CA). It uses Absorbed Glass Mat technology, which means it’s spill-proof, sealed, and vibration-resistant. The ultra-low internal resistance helps deliver power quickly, and you can mount it in almost any position.
For a daily driver with a 1,500–2,000 watt amplifier, this battery handles the load without breaking the bank. The M6 terminal bolts are sturdy and accept common ring terminals. At roughly 40 lbs, it’s manageable to install but still provides enough reserve capacity to keep your system stable during heavy bass lines.
- Strong 65 Ah capacity for daily use
- Spill-proof AGM design for flexible mounting
- Good balance of price and performance
- Not enough for 3,000W+ systems
- Can be heavy for some installations

- 5000A Car Audio Battery
Buyer’s Guide: What to Consider
Choosing the right XS Power battery for car audio means balancing power output, physical size, and your system’s electrical demands. The following factors will help you narrow down which model fits your setup, whether you’re upgrading a daily driver or building a competition vehicle.
- Power Rating (Max Amps and CA): Max amps indicate the instantaneous current the battery can deliver. Cranking Amps (CA) measure starting power. For car audio, higher max amps help prevent voltage sag during bass peaks. Match the battery's max amps to your amplifier's fuse rating — a good rule is 1,000 max amps per 1,000 watts RMS.
- Capacity (Ah and Reserve Capacity): Amp-hours (Ah) tell you how long the battery can sustain power. A higher Ah (e.g., 75 Ah in the D6500) is better for extended listening without the engine running. Reserve Capacity (RC) shows how many minutes it can deliver 25 amps. For daily drivers, aim for at least 50 Ah; competition builds may need more.
- AGM vs Lithium Chemistry: AGM batteries are affordable, spill-proof, and handle deep cycles well. Lithium (LTO) batteries like the PWR-S5 are lighter and last longer but cost more and require specialized charging. Choose AGM for reliability on a budget; choose lithium when weight and burst power are critical.
- Size and Fitment (Group Size): Batteries come in standard group sizes (e.g., Group 48, Group 65, U1R). Measure your existing battery tray or intended mounting location. XS Power offers direct-fit models (D4800 for Group 48, D6500 for Group 65) and universal cells. Always check dimensions before buying.
- Terminal Type and Hardware: Most XS Power batteries use M6 terminal bolts (some use M5). Ensure your ring terminals match. Some models include top-post adapters (like the D3100). For flexible wiring, models with I-Bar integration (PS1200L) offer multiple terminal positions.
- Vibration and Mounting Flexibility: AGM batteries are spill-proof and can be mounted in any orientation, but some are more vibration-resistant than others. If you off-road or drive on rough roads, look for tightly packed AGM designs (like the PS1200L). All XS Power AGM batteries are sealed and valve-regulated for safety.
- Budget and System Size: Prices vary widely: compact supplemental batteries (XP600, XP750) are the most affordable, while large main batteries (D3100, D6500) cost more. Lithium batteries command a premium. Don't overspend on a huge battery if your system is under 2,000 watts — a D3400 or PS1200L will suffice.
Conclusion
XS Power offers a battery for nearly every car audio scenario — from the compact XP600 that sneaks into tight spaces to the massive D3100 that powers 5,000-watt systems. The key is matching the battery’s amp rating and capacity to your amplifier’s draw and your listening habits. For most daily drivers with moderate systems, the D3400 or D6500 are excellent main battery options. If you need a secondary battery, the XP750 or D975 provide solid reserve without breaking the bank.
Ultimately, your choice comes down to space, power needs, and budget. If you’re building a lightweight competition car, the PWR-S5 lithium battery is hard to beat. For everything else, AGM models like the D4800 or PS1200L offer proven reliability. Whichever you pick, upgrading your battery is one of the best investments you can make for clean, consistent car audio performance.
