BankManager™

Both the Gen2 and Gen3 units work for 12V, 24V, 36V, or 48V systems, and can be used for marine, RV, off-grid homes, and other hybrid battery applications. For more about each case style, visit the sales page. For a comparison between the Gen3 and the Gen2 units, visit the features page. 

NOTE:  Our default current sensor  is sized for 200A of charging or discharging.  This is approprate for 90% of our customers.  If your system moves more then 200A, other current sensors are available.  As the current sensor gets larger, its percision decreases, but even the 600A sensor would work in any system (You just might see the 10ths-of -amps display jump past some digits.)

If don't use the 200A sensor, you need to tell your BankManager™ what you have installed. You can do this via the menu when you set up your system.

NEW! BankManager™ Gen3(A) - ALL-IN-ONE

The “All-In-One” unit takes all the hookup wires right to the one unit. If you are upgrading from a Gen1 or Gen2 BankManager this would be the easiest upgrade as the case has the same footprint as the Gen2 and uses the same hookup wire order as the earlier offerings. This case is the least complex, with everything in the one box. This is especially useful for installations that mount the BankManager™ near the batteries, or if the user doesn't mind running several wires to the display unit. 

This unit includes a sensor and is compatible with the Universal and Generation 3 spare/replacement parts listed below. 

Note: Installation requires an appropriate contactor, sold separately. (See below.) 

$550.00 USD

NEW! BankManager™ Gen3(S) - SURFACE MOUNT

The surface-mount unit offers the smallest display unit, and does not require holes to be drilled into your boat. Its ethernet wires come out of the bottom of the display unit. This unit includes a sensor and is compatible with the Universal and Generation 3 spare/replacement parts listed below. 

Note: Installation requires 2 ethernet cables (not includeed) and an appropriate contactor, sold separately. (See below.) 

$560.00 USD

NEW! BankManager™ Gen3(F) - BACK / FLUSH MOUNT 

The back-mount unit allows you to hide the wires going to the BankManager™, as all wires enter the unit through the back. It may optionally be flush mounted, similar to other modern boat instruments, and includes a trim ring that helps achieve a professional-looking installation. This unit includes a sensor and is compatible with the Universal and Generation 3 spare/replacement parts listed below. 

Note: Installation requires 2 ethernet cables (not includeed) and an appropriate contactor, sold separately. (See below.) 

$570.00 USD

BankManager™ Gen2

This unit includes a sensor and is compatible with the Universal and Generation 2 spare/replacement parts listed below.

Note: Installation requires an appropriate contactor, sold separately. (See below.) 

$380.00 USD

BankManager™ Bistable Contactor BEST CHOICE 

A contactor is required to install your BankManager. We offer a high-quality, 300A, continuous-duty bistable contactor specifically made for BankManager™ units.  This device is well manufactured in the United States by a company in North Carolina. We recommend all users add this item to their order. 

If your installation will need to pass more then 300A continuously, you can use two of these contactors in parallel.

If you prefer to supply your own contactor, please contact us about compatibility. Most any normally-open, normally-closed, or bistable contactor with low-side signaling will work, though our installation manual is written to accommodate our custom contactors. 

(Note: 48V/36V versions now available!)

$180.00 USD 

BankManager™ Monostable Contactor  BUDGET-FRIENDLY 

This is a budget-friendly alternative to the bistable contactor. This device should ONLY be used with 12V or 24v systems, and requires you to set our BankManager™ to monostable mode through its menu during setup. See the manual for full details. 

Please note: This contactor is rated by the Chinese manufacturer for 200A. Note that this is a monostable relay—so it constantly uses a nominal amount of power to remain in the “on” state. (It’s not a lot of power, as it has an economizer circuit—just milliamps—but it adds up. So if you want to minimize waste, we recommend the bistable contactor above instead). 

If you prefer to supply your own contactor, please contact us about compatibility. Most any normally-open, normally-closed, or bistable contactor with low-side signaling will work, though our installation manual is written to accommodate our custom contactors. 

$100.00 USD 

SPARE OR REPLACEMENT PARTS

If any part of your BankManager ™ device order arrived damaged, contact us for a return and replacement.

UNIVERSAL PARTS

BankManager™ Universal Current Sensor (Spare/Replacement)

Please choose your charging amperage. 200A is adequate for 90% of applications.  If your system moves more then 200A, other current sensors are available.  As the current sensor gets larger, its percision decreases, but even the 600A sensor would work in any system. (You just might see the 10ths-of-amps display jump past some digits.)

If don't use the 200A sensor, you need to tell your BankManager™ what you have installed. You can do this through the menu during setup.

If you think you need a sensor with higher amperage, please contact us before ordering.
