RS4 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 RealPRO Series Battery Charger - 24A - 4-Bank (PN: RS4).

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
  • Less than 1mA sleep mode
  • Transfer rate up to 7.5A
  • Self-powered
  • Any type of battery chemistry

Used in Any Application Where Batteries Are in Series:

  • Marine
  • Golf
  • Industrial
  • Aerial Equipment
  • Solar Power
  • Electrical Vehicles
  • Communications
  • Defense/Military

Works pretty good, it sticks to polo tshirt polyester material better than the inside of fleece hoodies. One roll lasts me for a bunch of clothing pieces. The tape didn’t leave any residue on clothing.

Vibrant Results and Great Value!
Size: 13"*19", Color: 150 sheets
HTVRONT Sublimation Paper 13x19 inches – 150 Sheets Review I recently purchased the HTVRONT Sublimation Paper (13x19 inches, 150 sheets, 120g) and I’m genuinely impressed with the results! As someone who does a lot of sublimation printing for both personal and small business projects, I found this paper to be a fantastic choice. Pros: Excellent Print Quality: The colors transfer beautifully and vibrantly onto my blanks. Images come out crisp and true to the original design. Generous Size: The 13x19 inch sheets are perfect for larger projects like T-shirts, tote bags, and even custom pillowcases. It’s great not having to piece together smaller sheets. Easy to Use: The paper feeds smoothly through my inkjet printer with no jams or smudging. Instructions were clear, making the process straightforward even for beginners. Consistent Results: Every sheet in the pack performed consistently, with no noticeable defects or wasted paper. Value for Money: With 150 sheets in the pack, it’s a great deal for the price, especially for anyone who does frequent sublimation work. Cons: Requires Sublimation Ink: Just a reminder that you’ll need sublimation ink for best results (not regular inkjet ink). Storage: The large size means you’ll need a bit of space to store the pack, but that’s a minor issue. Overall: I highly recommend the HTVRONT Sublimation Paper for anyone looking for reliable, high-quality results. It’s perfect for both hobbyists and small business owners. I’ll definitely be purchasing again!
