Not sure
I plugged it into my 48v Titanit 40Ah battery bank voltage did not move it’s been plugged in for about an hour now it was getting warm to the touch when I first connected it so I rested it on top if 1 of my battery chargers that’s not plugged in because it’s got a metal case it’s now about an hour & a half it was about 12 noon and now it’s 1:28 pm I go down and see if it’s gotten smoking hot or not ! It’s slightly warmer to the touch ! Do Know if it’s doing anything or is it just paranoia buy !

Save your money
I have had this for about 5 months now and in my opinion it has not helped at all. My cart batteries were 2 years old when I added this product to my cart and I can see no improvement what so ever

Battery Life Saver
I cannot really rate the product & gave it 3 stars simply because the company was helpful & the product arrived promptly. It was also easy to install. 2 of the bank of 4 12V batteries I hoped to use it on had open cells, so I decided to go ahead & purchase all new batteries. I left the BLS installed in hope that it may be a help in extending the life of the new batteries. My infrequent use of the golf cart has lead to battery problems in the past. It will be a very long time before I would be able to say whether or not the product works as described.

It may have helped!
It may have helped! Have had it installed on my golf cart for about three months and it hasn't been a miracle product but there may have some improvement.
