BLS-48A 48v Battery System Desulfator Rejuvenator

I had heard that these things did not really work but the system works wonders!! I have 32 golf cart batteries for my off-grid home and after having them for 2 years I saw that they where loosing strength but with the BLS wow they are back like new. I can do a lot more loads and they are taking the beating like if I had just bought them. Highly recommended. I was planning on getting lithium batteries but not anymore, these lead batteries will last longer with the BLS. once you install it you have to wait around 2 months to see the difference and you will for sure.

Easy to install, seems to be working well but only time will tell.

Well, I had my doubts, I decided that, $ 130 vs. 4 new golf cart batteries that could be in the range of $ 700 could be worth it;. It took longer than they projected, but it really works. My cart went from being very slow, even after an over night charge, to one that jumps when I press the accelerator.Well worth the investment. I batteries are approx. 5 years old.

Working on third 48v pack. Seems to do the desulfation trick in arround 3 to 4 weeks.

Installed this devise after noticing that my fully charged battery could barely make it back to the cart storage barn after an 18 holes round. Had it in for three weeks and didn't notice any improvement on the battery performance. If anything the batteries got weaker after a round of golf that the cart had to be pushed to the cart barn. I gave it 3 star as a benefit of a doubt since the batteries on my cart are 5.5 years old and I use the cart at least 5 days a week.I installed new batteries on my cart recently but not sure if I should reconnect the BLS since it consume power too and can't really tell if it does what it supposed to do without immediate obvious indicator.

very good indeed

This product as raise the batteries efficiency about 5%,it is really doing a great job. It’s
