True Cousins offers the most powerful and safest lithium batteries on the market—and the best prices when comparing actual values for Ah, Wh, and CCA. We also have the most extensive knowledge and hands-on experience, as we have been selling lithium starter batteries for Danish motorcycles and cars since 2014 and are also deeply involved in building hyper-performance lithium batteries for drag racing at the highest level with our lithium-battery-powered dragsters.

Jigawatt LBB-S Series, lithium-ion starter batteries for motorcycles

The most powerful motorcycle battery on the market, lowest price per Ah, built-in safety features for over- and under-voltage protection, a voltmeter, and smart multi-position terminals with connections on three sides.

Jigawatt LBC-SP Series, lithium-ion starter batteries for cars

Brand-new version of our lithium starter battery for cars, with up to 2500 CCA and 95 Ah. Significant weight savings and 50–150 start attempts. Includes built-in safety features. Can also be used to power applications such as small boat motors, lawn mowers, or as a booster.

Special batteries: 16, 24, and 48 volts

True Cousins offers some of the best and most powerful custom-built lithium batteries in the world.
We offer 16-volt batteries in both starting and ignition versions, as well as ignition-only versions. However, we can build batteries of ANY size or type, and in the past we have produced small batches of 24- and 48-volt batteries—some of which were used for tractor pulling.
