It’s a quality product. IMO their batteries have become overpriced. I had two BB 100ah. User error damaged the BMS on one of them. I replaced it with a Li Time TM for 1/3 of the price.
I haven’t decided on a BMS yet. I didn’t know that Walmart had cases. I found some on eBay for under $50. Any recommendations for a BMS? I’ve been looking at JBS
