Battery Optimization System (B.O.S.) - 12V - 4-Bank

The Pro Charging Systems Battery Optimization System keeps batteries balanced enabling maximum performance. The system can quadruple run time on the water for boaters and other users.

Premature battery failure due to an unbalanced pack has unfortunately been accepted as the norm for decades. The B.O.S. breaks through those accepted norms and solves the problem with a BSAP-24 algorithm that can accurately predict and select the battery that needs additional energy to match the other batteries within the pack. This simultaneously and successfully extends the life of each battery in the pack. The net result is substantially increased run times and extended battery life.

The Battery Optimization System is the perfect companion device to utilize with Pro Charging Systems advanced battery chargers.

B.O.S. is compatible with PROView Link battery monitoring software that enables you to monitor your battery status via your smart phone or tablet. The PROView Link App is available to download for free at the Apple and Google Play stores. Learn more about the capabilities of PROView Link at the Energy Management page.

Fun Dog Fetch Balls
Color: 3 Colors
Ordered these for my dog for Christmas and he loves them. He has a blast running up and down the hallway with them. Easy to play with, cute and fun. Not very noisy, I actually didn't know they squeaked until I stepped on one. Very quality and sturdy. Good value for the money. Package arrived timely and as described. Would definitely order again.

Tough ball. Perfect for large chewing breeds.
Color: 3 Colors
My German Shepherd Dog is a year and half old, and she loves these. They truly are pretty indestructible. It took her a little bit to figure out how to squeak it bc they are tough, but now it’s easy for her. They bounce well too. They are larger than a normal tennis ball but a good size for a large dog. Luna is 85 lbs. I would purchase they again, but I probably won’t need to for awhile.

Enjoyable For Our Dogs
Color: 3 Colors
Very durable material. They have a little squish too them for easy pick up for our 50 pound dogs. Our dogs love all balls. They have a little weight to them, but not excessive for a medium to large size dog. We have an English Springer Spaniel and a Goldendoodle. Fun for playtime, but you probably won’t want to throw them around the house.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.
