This NDS LiFePO4 battery has a capacity of 100 Ah., making it suitable for general use in a motorhome, caravan, boat or other vehicle.

Like other 3Lion batteries, it comes with an internal battery management system as well as an external “3Link” and a touch-screen, full colour display which shows the battery’s state of charge as well as current flow and voltage. It also shows the voltage of the engine’s starter battery.

The 3Link unit removes the necessity to alter the cabling of a vehicle while ensuring maximum charging from the alternator. The 3Link supplied with this battery permits a maximum current draw of 100 Amps. 

If the vehicle is fitted with a "smart alternator", it will be necessary to fit a suitable battery to battery (DC-DC) charger as well.

IMPORTANT!!  Installation of any LiFePO4 lithium battery is not difficult. However, if the battery is to work efficiently and safely for its estimated lifetime, it's essential that it is installed correctly. This means that the charging voltages of the alternator, the mains charger and a solar panel if fitted are appropriate for the battery. If they are not, the battery can be quickly damaged.
