From a powerful battery to a formidable power station. That is what the GIANTZ Deep Cycle Battery and Battery Box combo can do. On its own, the 135Ah 12V battery features an incredible cycle life of up to 1600 cycles. What you get is a longer, consistent and more drawn out charge all the time. And with its advanced AGM technology, the battery enables better electrolyte absorption, cyclic stability and frequent charging without affecting performance. The bolt down terminals also allows for more reliable experience, and not least, the high oxygen-recombination efficiency results in superior deep discharge recovery. And not to be outdone, the battery box easily fits the GIANTZ deep cycle battery and together, they can power up a host of 12V devices including camping lights and portable fridges with its cigarette lighter socket as well as mobile phones and tablets with the two USB ports. The box itself can be charged using solar panels or any power source with its quick-connect Anderson plugs. Better still, the box comes pre-wired, so all you need to do is to connect to the deep cycle battery terminals and it is good to go. More power to you. That is definitely true with the GIANTZ deep cycle battery and battery box.
