Lithium Ion battery for cars vs the usual wet cell battery

The use of Lithium batteries in cars, motorcycles, heavy vehicles and off-road equipment is increasing rapidly. For the same energy content, Lithium-ion weighs about 4-times lighter than lead-acid batteries, but will cost about 6-7 times more.

Within these industries different types of batteries are used. The main categories are: 12V starter batteries, 48V batteries (new board net standard) and EV batteries. Super B is specialized in the 12V and 48V solutions.


Lithium batteries vs conventional batteries: Some numbers

  • Up to 80% weight saving
  • Charge and discharge at high currents: Charging times of 5 minutes can be reached.
  • A lithium battery offers phenomenal starting power and massive deep cycle reserve power. They are capable of providing engine cranking pulses of 2250 amps for 5 seconds.
  • Longer lifespan with a minimum of 5 years’ service life, up to 10 years depending on use
  • Motorsport has long served as a proving ground for developing and improving vehicle technology. A lot of racing series provides an ideal research and development platform for pushing the boundaries of mainstream vehicle technology. At present, research into rechargeable Lithium Iron automotive batteries is being driven mainly by the requirement in the automotive industry for long service life and charge lifetimes, high discharge currents, the need for rapid charging, and, additionally, cost targets.
