Powerwinpower Reviews 

The battery doesn't have a bms port, however is working fine with my PowMR inverter. It was delivery fast, the battery works as expected to live completly off grid. I hope to have it working for at least 10 years.

I had order 2 battery from you last year and just charge them after receiving, but use them. However, over the year they hardly lost any of their charge. Now, I order the third one to power my new 36v trolling motor. So this summer I will find out how they really work. Thanks

The fast and efficient service was great. My communication with Nikki to negotiate a fair price for both of us was very helpful with the budget I was working with. The batteries showed up in just a few days and there lightweight made them easy to move. I'm still waiting for my cool Powerwin stickers for the kids but thats my only gripe!

I have two of the lithium batteries BT – 100 series, I use their 50 amp solar charge controller and I have a 220 W folding solar panel. I've had no issues with any of the equipment! Their equipment is lower cost but maintains high-quality so they get five stars from me. POWERWIN is inexpensive and reliable.

Excellent price and fast shipping. Device arrived without damage and works fine.

Fantastic customer service. Your people are great and your products outstanding. I would love to be able to own some of your higher-end products and my some day. We live on an island that experiences power outages frequently during the winter months and having a power alternative is critical.

Ordering was very easy, and shipping was quick!

I initially ordered my Pps2000 with the 110w Portable solar panels back in December of 2022 as part of a Christmas bonus promotion, my power station came relatively quickly but my portable solar panels didn't.... Fast-forward 6 months, I'll decided to reach out to the company (powerwin) about my missing solar panels, initially there response was that my initial order didn't come with the bonus solar panels, but.... after a few emails back and forth, it was determined that yes, my order should have came with the solar panels, they're honored the original promotion and shipped my solar panels today, I'm excited to try them out! I'm very happy with the customer support, especially April, who was my contact person throughout the whole experience A+ all around, excellent products, good customer service!
