I have not had any issues thus far. I purchased this battery for 2024 Subaru. Mostly to save weight around 25-30 lbs. May not seem like much but I feel slightly better braking and acceleration. I think this is due to the location of the battery as it seems work perfect to help balance weight under the hood.

This battery is super light and has tons of power. My car starts faster and feels like it has more power while running now. I'll only use lifepo4 batteries from now on.

My car starts quickly every time with this battery. It’s lightweight and very efficient. Highly recommend Powertex!

I replaced my old lead-acid battery with a Powertex lithium, and the difference is night and day. My car feels lighter, and the battery is much more reliable. I’ve noticed quicker starts and smoother performance overall. Highly recommended

I’ve had my Powertex lithium battery for over six months now, and it’s still going strong. I appreciate the reliability, especially during longer drives. It holds a charge much better than my old battery, and I haven’t had to worry about jump-starting since switching. Great investment

The Powertex H8 lithium battery has been a reliable power source. It’s lightweight, long-lasting, and starts up quickly every time.

I’ve noticed a significant improvement in performance with the Powertex 48 lithium battery, especially in extreme temperatures. It’s the best upgrade I’ve made.

Switched to a Powertex H8 lithium car battery in my 2018 BMW 5 Series, and I’m amazed by the performance! My car starts instantly, and the battery is much lighter than my old one.

The efficiency of the Powertex Q85 lithium battery is remarkable. It lasts longer, charges faster, and is a perfect fit for my needs.

The Bluetooth connectivity on the Powertex H6 lithium battery is super convenient. I installed it in my 2020 Mercedes-Benz C-Class and can check the battery status right from my phone. Powertex did an excellent job with this one!

I was skeptical at first, but the Powertex 35 lithium battery exceeded my expectations. It’s lightweight, powerful, and lasts much longer in my 2015 Toyota Camry than traditional batteries.

I upgraded to a Powertex lithium battery for my off-road vehicle, and it’s been fantastic. The battery handles the rugged conditions perfectly, and I’ve noticed a significant improvement in power delivery. Plus, the weight savings are a big plus for off-roading. Highly recommended

The installation was easy, and the performance of the Powertex Q85 lithium battery in my 2018 Nissan Leaf is outstanding. I haven’t had a single issue since I switched to this lithium battery. Five stars!

This is the second LifePo4 battery I’ve bought from Power Tex. Can’t beat them for weight reduction, power and voltage retention. First one is still rocking strong two years later. Really like the new just start feature built into the batteries now.

I’ve been using the Powertex H6 lithium battery in my 2017 Audi Q5 for a few months, and it’s been fantastic. The advanced BMS really makes a difference in managing the battery’s health.
