Fairly light weight at 80 lbs. Only took about a day to fully charge with solar panels, and it runs my 3000 W inverter with no issues. 400ah is well worth getting instead of 4-100ah batteries connected together due to less wiring and possible loose connections. Highly recommend.

400 Ah Battery

The battery is great. I am having some problems connecting to the Bluetooth. There doesn't appear to be a QR code that came with the battery.

I received the battery in 4 days

I haven't had the chance to use the battery yet but the quality of the case and the weight was much less than the old 6 volt batteries plus the energy storage should be hugely beneficial.

Fantastic easy to charge and hook up!

We received the battery with no issues, right on time. We charged it up over night and hooked it into our invertor the next day. Everything went smoothly and we are very pleased with the power accessible.now even with the rainy days. Yay!!

I’ve been using the battery primarily as an emergency power backup at home — it gives me peace of mind knowing I’ve got reliable energy if the grid goes down.

The lightweight design is a game-changer for someone like me, who spends a lot of time outdoors. I use this battery regularly to power all my electronics during trips, and it has never let me down.

Drop in for our travel trailer Great addition to our travel trailer. Now we can spend endless time at a remote campsite without worrying we will run out of power.
James
Omg awesome! Things are looking great so far. With all the great reviews on the web. I’m feeling pretty good about the two 200 AH batteries I bought. Thank you for a great product

Installed 2 100ah batteries in boat as my house bank with the Litime DC to DC 40amp charger to protect alternator. I have to say very happy with everything.
