This lithium battery is in a case that's the same size as the industry standard for 100Ah lead-acid batteries. This makes it ideal when space is restricted, including when the battery needs to be located under one of the front seats. It comes complete with 3Link junction box and a touch-screen display which gives you all the information you need about the condition and performance of your battery.
