Dual Pro Battery Optimization System 12v 4 Battery in Series 48v System

Model: BOS12V4
  • Approved for use with Wet Cell, AGM and Lithium Ion batteries
  • Designed for 12V batteries
  • Designed for use in fresh and saltwater
  • BSAP-24 Battery Selection and Prediction Algorithm on board
  • Less than 1mA sleep mode
  • Self-powered

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.

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.

The Battery Optimization System is compatible with most Lithium* batteries.

*Always verify with PCS before using with Lithium batteries.

*Use PROVIew™ Link to configure B.O.S. for use with approved lithium batteries.

Great Value...Great Fit....Works Great!
For the money, this is a great value, and if used properly, should last as long as your N55 engine....the construction material may cause it to distort, and may be difficult to separate from the filter assembly, but if this occurs, the cap was installed too tight or it's being installed too tightly...cranking on the plastic oil filter canister lid without disregard to propr torque value will result in needing a new filter canister lid and/or tool.....I'd buy this product and same mfg products....

Not a bad oil filter wrench, actually!
Lots of hit or miss reviews here, but for me, it fits like a glove and easily allows me to apply the 25-26 Nm of torque needed to open or close my BMW oil filter cover (2020 M4 but most BMWs use the same type of filter cover). It does get on there pretty tight and might be hard to remove. Solutions: - wait for the engine to cool down a bit, and it will come right off - use a pick tool to loosen it

Great value and Perfect Fit
This little oil filter wrench fit my BMW M340i perfectly and made the job a breeze. It locked onto the cap snugly, with no slipping or wobbling, and let me remove and reinstall with confidence. The material feels sturdy for the price and if you use the proper torque instead of cranking down on the housing, it should last a long time. Highly recommend for DIY oil changes.
