12V Antigravity Small Case Lithium Ion Batteries

The Antigravity "Small Case" lithium ion batteries offer the most power and performance in the most compact size. They can be used as ultra-light battery for race vehicles to save space and weight, or for fitting into Custom and Performance motorcycles which require a small battery that keeps the look and at the same time delivers enough power to turn the starter. Can hold a charge up to a year provided there are no permanent drains, i.e. accessories that draw power when the bike is off, such as alarms, ECUs, GPS, clocks etc. Antigravity Small Case batteries can be installed in any orientation, feature unbreakable brass terminals and come in power levels from 120 to 480 cranking amps.

Capacity is indicated as "xAh Pb Eq" (lead equivalent), because the usable capacity of Li-Ion batteries is typically 3 times higher than an equivalent lead-acid accumulator. In other words, the value indicates which size lead acid battery would be required to deliver the same starting work.

Lithium-ion batteries require suitable battery chargers. Automobile or motorcycle chargers for lead/acid batteries can cause damage to Li-Ion batteries because they charge in a different way.

Regulators for Li-Ion Batteries

The upper limit for charging voltage is 14.4V. Antigravity recommend Cycle Electric regulators, who have a reputation for respecting this limit.

For the AG401 and 801 we recommend Cycle Electric's Low Voltage Regulators from our own experience.

Two batteries in parallel connection

Whoever - e.g. for reasons of space - intends to connect two small batteries in parallel, does not do any good to his regulator. Vehicle regulators are designed for charging only one battery. If you are connecting a second one in parallel, there's always one of the two that gets too much charge while the other one is starving to death. So please and in your best interest, provide some space for a single, but adequate battery and ride safely.
