Charging Lithium Ion batteries

Although Lithium Ion batteries are increasingly popular, there can be a lack of clarity when it comes to the charging process. This is not a problem with Mastervolt as the Mastervolt battery chargers communicate directly with the Lithium Ion battery via the integrated MasterBus (or have been adapted to the required charging voltages).

MasterBus compatible

Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local, or remote monitoring, configuration, and control of your system.

Made tough by smart design 

The certified Mass battery chargers are very strong and designed to withstand heavy vibrations and shocks. Their premium quality components meet the highest possible specifications, while the smart and extra robust mounting adds to the professional end result.

Dual Pro RS3 3 Bank Battery Charger w/3 Bank B.O.S. [RS3/BOS12V3]

RS3 3 Bank Battery Charger with 3 Bank B.O.S.

This kit includes Dual Pro’s B.O.S. (Battery Optimization System) - 12V - 3-Bank (PN: BOS12V3) and Dual Pro’s RealPRO Series Battery Charger - 18A - 3-6A-Banks - 12V-36V (PN: RS3).

B.O.S. (Battery Optimization System) - 12V - 3-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

Xantrex Freedom XC 1000 True Sine Wave Inverter/Charger - 12VDC - 120VAC - 1000W/50A [817-1050]

Freedom XC 1000 True Sine Wave Inverter/Charger - 12VDC - 120VAC - 1000W/50A

True sine wave 120 Vac inverter/charger with built-in transfer switch. Designed for recreational and commercial applications.

The Freedom XC inverter/charger offers premium performance in a lightweight compact package. It cranks out full output in invert or charge mode from -4°F - 104°F for operation in all climate temperatures. The extended surge rating of the Freedom XC makes it ideal to start difficult loads including fridge and microwave. The quick connect terminals at AC IN/OUT make installation a breeze.

Inverter Features:

• Extended Surge Rating: Surges to 2X continuous power for 2 seconds for motor loads
• True Sine Wave AC Power: For operation of sensitive and motor loads
• Ignition Control: Feature to turn inverter on/off via a 12 VDC signal and to minimize battery drain by switching the inverter off when the ignition key is turned off
• Wide 10-18 VDC Input Range: Ensures inverter operation on high voltage alternators found on many new vehicle chassis
• Programmable AC Under-Voltage (85-110VAC) Shutdown: Feature ideal to operate under weak shore power or generator input
• Built-in 30A AC Transfer Relay: Senses when outside AC Power is present and transfers the load from the inverter to the source of incoming power (shore or generator). The unit also automatically switches from invert mode to charge mode

Built-In Charger Features:

• Power Factor Corrected Multi-Stage Charging: Utilizes less shorepower when charging batteries. This frees up more usable AC power for running electrical devices and appliances and reduces the likelihood of tripping shorepower breakers
• Programmable: Configurable 3 stage temperature compensated battery charge algorithm for optimal charging of almost any battery type up to 18V
• Battery Equalization: Maximizes flooded battery life
• Dead Battery Charging Down to 0 Vdc
• Power Share: Prioritizes AC loads by reducing the charge current and maintaining the total input current to less than the breaker setting
