Five star review all the way. Awesome quality and price. Very powerful system and does everything I need from it. I have it mounted in my campervan and a solar panel on it for charging. Easily keeps up with all my requirements with charge to spare. The ability to monitor from my phone with the app is just the icing on the cake. Great product guys. Higher recommended.

Absolutely awesome battery, powered my Bushman's fridge and travel buddy oven with heaps of power to spare. Love the bluetooth monitor, it makes it so easy to keep check on what is happening with the battery

The lithium battery that is maintained with that same capacity v13.25.35 Hms I was using it for 9 hours charging 5 things at the same time from chargers I only go one line I am in the brand's representative HardkoRR.

Purchased 2 of these, upon charging them back to 100% so they could be wired in parallel, straight out of the box one of the bluetooth dropped out completely. I tried resetting BMS, re-installing app tried another phone then called supplier where I purchased from and was advised this has been happening with a few straight out of box? the fix apparently is to completely drain the battery and let sit for 24hrs then use the BMS reset cable to wake the battery back up. If it works I will repost with results. If this didn't happen I would of given it a rating of 5 stars as the other one is perfect :)

Fantastic product, value for money, worth every dollar. Overall a very High quality product.

Battery is light and has good discharge current limits. running 2 in parallel feeding a 2000w inverter and runs out van ac unit drawing 65amps. App Works Well to monitor battery state and charge level.

Outstanding product

Awesome product. Can't fault it. Heaps of capacity. Ran a 45L fridge (all day) with camp lights (during the night) over a 5 day camping trip and it dropped only 27% without being charged 🤙🏼🤙🏼
