XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery with M6 Terminal Bolt

Works well so far; this high-quality AGM battery effectively powers my stereo system and provides reliable starting performance. The vehicle requires significantly more cranking amps than what I need for daily use, and the battery handles this with ease, maintaining excellent condition and durability.

I've got this powering my X15v3 on a Taramps MD3000.1 and I've had no issues thus far. When I purchased it though, I wish I'd have realized that it didn't come with battery terminals lol Had to wait another day or 2 for those to come but otherwise, this thing has done exactly what I've wanted it to and had no issues. Would absolutely recommend and when I inevitably upgrade my stereo again I will be buying a few more XSPower batteries.

This battery batteries so damn hard. Don't forget your accessory kits though, posts and side terminals are not included. Worth the cost!

Using a smart bass 3 and two AB xfl 12s. I read so much about how anything over 2k needed alternator upgrade, etc. But I gotta tell you.. I turn the volume up to clip, which on these subs is dang loud. And my voltage stays at 14.7. I thought my volt meter was broken. Then finally it began to dip super hard. To 14.4 lol. So I'm like wow, I think I can run all 4k of my power on stock electrical with just this one battery. Maybe if you run your system nonstop while driving, you will eventually run out of juice. But for me, I only play the music loud maybe a half hour at a time and the rest is probably pulling maybe 500w tops. Just at everyday listening volume. So for me, it's been awesome. It gives me the power when i feel the need for it, voltage stays strong and no dimming unless I really go crazy and even then it is only the trunk lights and dome lights, the headlights aren't really noticeable. This is on stock electrical so I'm even surprised that it does this well. Before this battery, no chance I was doing more. I was on 1200w and it was dimming like crazy. So not only am I on triple that power now, but the dimming is barely there. And the voltage appears to be extremely strong. This battery is really powerful. To hear the power from this setup and know most of it is coming directly from this battery is extremely impressive.

Battery holds up nice to my 400a mechman alternator in my 2012 Tahoe thinking about getting another

Way over priced does not stay charged at all!!!! Tryed to get amazon to help get it warranties they would not do a thing. So i contacted xs power them selfs they told me i had to send it back at my own cost and they would see if it is bad and if it is they would then send me a new one witch would in effect leve me with car for a lest 1 full month total crap have had issues with it from bay one will stay charged for more than 1-2 days and i have nothing in my car after market at all just a worrible battery with horrible customer servacez DO NOT BUY ANY THING XS POWER EVER TRASH

All these people on here saying it only lasted xx long is because they most likely let it die and just threw a battery charger on it or jump started it and not realizing or reading the paperwork that came with the battery it clearly states proper charging is crucial #1 you need an AGM battery charger these are special in that it puts out a MAX of 2.4 volts per cell 2nd temperature is huge AGM batteries operate with less electrolyte possible on a slight air pressure. This air pressure allows the water produced under discharge to condensate therefore recycle inside the battery under proper charging (voltage and temperature) almost no gasses escape but overcharging will cause small amounts of electrolytes to be "gassed" out of the safety valves and once the oxygen is vented it cannot be restored results will be reduced capacity not accept charge etc.. these are permanent and void warranty

Holds charge well, came in good condition and weight is accurate as well.

Delivery was fast.I have 2 of them for my Sundown setup.They look and perform great.

Very Heavy and expensive customer service is basically non existant

Overpriced and fails just after warranty.
