For our BWB LiFePO4 Batteries, we only use A-Grade GFB Prismatic cells and DALY BMS. Apart from that, we also use double coated 3M foam tape between every cell for shock absorption, fiberglass tape to keep the cells together, and high-quality epoxy resin boards as the insulation board.
The cells are covered by foam on both sides as well as the bottom to help with vibration and external heat. In this way, the battery is built for performance in a harsh environment related to 4WD and boating.
BWB LiFePO4 Batteries are so Tough and Strong, that they will accompany you and your family to enjoy a relaxing time.

I had bought one before from another seller and it was just crap! Been looking around for good quality lithium batteries for few months until I stumbled into big wei in Google search. I never doubted this product and works just great. Good service too! Keep it up.

Purchased a 200ah lithium battery. Fantastic product. Arrived in a timely manner, fully charged, and a terrific upgrade in my caravan from the previous AGM batteries. I also contacted their customer support via email due to an issue of my making and their response was very timely and solved my issue. Very happy with this product and Big Wei and would certainly purchase from them again based on my experience with them

I have had the battery for a few weeks now and only had a chance to test it once. We went away to Teewah beach for 9 days and it didn’t let us down. We had 4.5 days of over cast weather and while everyone was scrambling for the generators we were all good.
Yet to test with an inverter which will be getting added to the setup soon
