PS4 Auto 4 Bank Battery Charger with 2 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. Battery Optimization System - 12V - 2-Bank (PN: BOS12V2) and Dual Pro’s PS4 Auto 15A - 4-Bank Lithium/AGM Battery Charger (PN: PS4AUTO).

B.O.S. Battery Optimization System - 12V - 2-Bank

B.O.S. actively shuttles energy between batteries to keep “the pack” balanced, increasing battery strength and longevity.

Batteries in a pack will become “out of balance” and the pack is only as good as its “weakest link”. In watercraft applications, this is further compounded when the trolling motor battery is used for peripherals and/or to assist the cranking battery.

B.O.S. actively shuttles energy as needed between batteries wired in series to ensure equal voltage before, during, and after charging.

B.O.S. keeps packs balanced, enabling maximum performance, and quadruple run time on the water.

Premature battery failure due to an unbalanced pack has been, unfortunately, accepted as the ‘norm’ for decades. The B.O.S. answers this call 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, as well as increasing run times.

Features:

  • Available in 6V, 8V, and 12V configuration
  • Up to six batteries in a series
  • Battery Selection and Prediction (BSAP-24) algorithm

Just buy them
Color: Black,navy,burgundy,brown, Size: Small
Used to wear sliders all the time, figured i'd switch it up. These are super comfortable, probably the best material underwear I own. Great to just lounge around it or wear everyday. Fit is really good, I got a small and about 29-30" waist. Good bang for your buck too. I've washed them a handful of times and they hold up great, fit great and dont' shrink.

Good underwear. Husband likes them.
Color: Black, Size: Large
Husband wears XL and XL fit well. This is the second pack I got for him. They are decent quality, look and feel nice, not baggy yet not too tight anywhere. They are somewhat thin (but still supportive) and do not make him sweat more so he loves that. No problems washing (they didn’t shrink). Will continue to repurchase these.

Comfortable
Color: Black,navy,burgundy,brown, Size: Medium
I have had a lifetime of different briefs, some name brand, some generic. I am 165 lbs, wear Medium, and these are closest to feeling commando of anything I’ve ever worn. Comfortable, not too tight waist and legs, and yes silky touch yet not slinky. Maybe not for support wear, but casual and cool comfort, the “Cat’s meow”. I just came on to order some more

Great fabric - pouch too small!
Color: Black, Size: X-Large
First, the fabric used is wonderfully soft and comfortable. It;s the first thing noticed when package was opened. Strange, but the elastic waistband is about 1/2", very similar to a woman's style panty. But it's comfortable and easily acceptable. The main problem is that the pouch that holds your "stuff" in place, is oddly and unnaturally small. Small enough where this average man's "stuff" tends to fall out of the pouch on one side or the other. I sleep in my underwear, and every time I did with these, I awoke with the front pouch off to the side and everything down there was hanging outside of the underwear. They also seem to do well through a wash cycle. However, if the main reason for wearing underwear is to keep your stuff in place, these fail from the beginning. I ordered another brand from overseas, and they had the exact same problems as these! I wonder if that's just how they make them outside of the USA. The Bottom Line? Uncle Steve Disapproved!

Premium cotton underwear at a modest price. Highly recommend!
Color: Multicolora6-4 Pack, Size: X-Large
Bought my husband 2 variety packs of these, and they are still great over 2 years in. High quality cotton briefs are breathable, colors are vibrant, and the fit is spot on. A good value at this price point compared to designer brands, and the product overall exceeds expectations in terms of comfort level, durability and appearance.
