Battery Box

SBD’s battery box was specifically designed for their drop rail kit, however you can use it in any location you see fit. They offer the Limitless 28AH Lifepo4 battery w/integrated smart battery management system for this. This is the perfect way to add a ridiculous amount of battery storage to your ride.


The Nano-HD is the strongest and safest battery available for Motorcycle and power sports applications.  The Nano-HD is a 28AH Lifepo4 battery with a integrated smart battery management system (BMS). Will replace the stock battery in any Harley Touring model.

The battery is made with “Left Positive” so it’s a easy drop in install that can be done by the most novice user with ease!

Custom Machined Wire adapters are available for easy install and hook up when many aftermarket wires are used in the install.

The main functions of the BMS is to keep the battery safe!  The BMS in the Nano-HD is designed to internally disconnect the battery if the preset parameters are ever met listed below.

Over Voltage / Charge:

The Nano-HD will internally disconnect if the voltage ever gets above 15.3. This is way above all motorcycle and Power sports normal voltage range so if this voltage is reached, more then likely there is a charge system problem and the battery will be safe no matter what the issue is.

Over Discharge / Low Voltage:

The Nano-HD will internally disconnect if the voltage ever falls below 10v. This is way below all motorcycle and Power sports normal voltage range so if this voltage is reach it would indicate a problem like a parasitic draw.  The battery Will disconnect itself to keep from being completely drained to Zero volts. The BMS will remain in the off or unhooked position until voltage from a different source is applied to the battery. At that point the BMS will turn back on to allow the bike or power sports vehicle to be started.

The Nano-HD can also be used with any other Limitless Lifepo4 Battery you may already own, They will all work together
