Glowe Voltage – Series 2 | Double the power. Half the cost.

Back in stock!

Voltage issues? Need extra power for your amps? Designing a monster car audio system? If so, you’re in the right place.

Quite possibly the best car audio battery ever made, the GV-S2 is able to support a 12,000 watt amplifier with stock charging. No other LifePo4 battery comes even close to this level of performance at this price. In fact: this battery easily outperforms others that are nearly 3x the cost.

Instead of just making wild claims about how good these batteries are – let us demonstrate. Check out how well the battery performs on stock charging in the video below:

It’s time to stop using battery technology that’s over 10 years old. Ditch your explosive CMAX cells. Get rid of the absurdly large rows of used Headway batteries. Welcome to the future.

Switched from 2 AGM 100ah batts to 1 Glowe, and what a difference!! I do extended jams at car shows with the engine off, and with the AGMs my voltage was down to 11.2 but with the Glowe it stays above 13!! Awesome

I pre-order my Glowe voltage lithium batteries and I was a little skeptical at first but after receiving it I was all but satisfied to the fullest. I ran 2 AGM batteries and wasn’t sure how it was going to work out, but let me tell you I still have one under the hood disconnected, and I have no intentions on connecting it. This thing works. I’m very satisfied.

Glowe Voltage Series 2 is a beast! Picked this battery up to get more performance then my stock battery could offer. On top of not wanting to upgrade my alternator right away. Stock battery delete in 2007 Cadillac Dts, only using the Series 2. Taramps Smart 5 pushing a single American Bass Xmaxx 12. I can full full tilt no problems whatsoever and my Voltage stays above 14v. Car on or off, all this with stock alternator. Once again I can vouch for this thing, absolute beast!
