12V Antigravity AG-401/4-Cell Small Case Lithium Ion Batteries
Antigravity "Small Case" lithium ion batteries offer the most power and performance in the most compact size for Harley-Davidson motorcycles. 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 to keep the "reduced" looks and at the same time delivers enough power to feed an ignition system and even to turn a starter.
Antigravity's Small Case batteries can hold a charge up to a year provided there are no permanent drains. Such drains are accessories that draw power when the bike is off: alarms, ECUs, GPS, clocks etc. Antigravity Small Case batteries do not contain liquids and can be installed in any orientation and come in different power levels.
As Li-ion batteries typically deliver three times the power of conventional lead-acid batteries, we specify the actual capacity in Ah and also indicate which lead-acid batteries (in Ah) they replace.
This battery is best used for kickstart only bikes or race track applications where extreme weight loss and ultra compact size are desired. It is also often chosen by custom builders who want the smallest battery to tuck out of the way.

Yuasa AGM 3Ah Batteries
Yuasa AGM 3Ah Batteries
With a base area of 104 x 70 mm and the option of installing them at an angle, these batteries are ideal for installation in a horseshoe oil tank or for space-saving custom projects. The low capacity and CCA below 100 do not allow for electric starts, but that's not part of the job in a classic Harley anyway. For kicking and as a buffer at low speeds (in city traffic, at traffic lights), the power is more than sufficient.
The Yuasa YTX series AGM batteries are delivered “wet-charged”: filled and charged at the factory, the acid is bound in special glass fiber mats. So no fiddling with acid packs and completely leak-proof. Just ready to go.
The 3 Ah YTX4L battery will fit best the bikes with basic electrics: just ignition, horn, lights.

EnerSys Odyssey AGM Batteries
EnerSys Odyssey AGM Batteries
In the Odyssey series by EnerSys pure-lead batteries meet AGM-technology. Here's some advantages:
Longer service life: Using high-purity lead and thinner electrode plates slows down grid corrosion, resulting in a longer lifespan., Higher starting power: Pure lead batteries have a lower internal resistance, providing higher starting power, especially in low temperatures., Lower self-discharge: The self-discharge rate of pure lead batteries is lower than that of conventional lead-acid batteries, allowing for longer storage without recharging., Low maintenance: Pure lead batteries are maintenance-free since they are sealed and do not lose water., High energy density: Thin electrode plates enable higher energy density, meaning more energy can be stored in a more compact design.,
Where room is sparse and small batteries are demanded, EnerSys Odyssey batteries are the choice. Odyssey batteries have to be isolated against vibrations and work best between -40°C and +60°C. The deep cycle discharge rate of 80% requires proper recharging to avoid sulfation, which in turn would destroy the precious battery. Short distance or low-mileage-per-year riders should seriously consider an applicable charger.
Implementing these low maintenance steps for the batteries will reward you with up to four times longer lifetime- compared to standard batteries - and low discharge rate.

Bates BattBoy HM5
Bates BattBoy HM5
Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in their horseshoe oil tanks will highly appreciate this fact. On the other hand, owners of classic bikes do like the looks of their original energy store and the corresponding cover and mounts. With a Bates BattBoy Battery Box you can have the best of both worlds, because what looks like a period type HM5 6V accumulator on the outside can house a safe, modern battery within. Just hook it with two eyelet wires to the terminals on the bottom of the lid and you are all set. Perfect for 6 to 12 volts electrical system conversions, too. When using suitable Antigravity versions you even have some storage room left for a few small spare parts, safety vest, Cuban cigars, etc. Ain't this one heck of a cool solution for an old problem?

Cannonball LION Battery Boxes
Cannonball LION Battery Boxes
Our electric start system just got even more stealthy.
The Cannonball Stealth Starter can give classic Harley Big Twins (with rigid or swingarm frames) the almost invisible option of starting by pushing a button. For reliable operation this system needs a powerful 12V Li-Ion battery, a solenoid, additional wiring and circuit breakers. To avoid an unsightly mess we developed this solution that incorporates everything inside a humble looking Harley HM5 battery case. From the outside it’s as stock looking as the 6V original, but the electrics inside are state of the art. In the two compartments there’s room for a 12 cell Antigravity Li-Ion battery and all necessary electrical components. A stock like lid looks as innocent as the vintage acid lead battery it replaces.

Batteries not necessarily for the original purpose

After performance measures on the engine, with a raised compression of about 2.0, your Harley may need a new starter motor. Most definitely, however, a more powerful battery, i.e. one that can deliver a higher current (cold start current, CCA) for the same size. Not necessarily more capacity, i.e. ampere hours (Ah), capacity is more important if the engine doesn't start at the first push of the starter button.

These two things tend to be confused: capacity is the charge of the battery, that is, how much energy it has stored in total. Current is how much of that charge the battery can deliver at one time. The higher the current, the faster/better the starter motor will work. The higher the capacity, the longer it spins.

Bike rebuild - battery redesign

If the starter motor is eliminated and also the electrical system is rewired, or if a different oil tank is installed, many also immediately think of a new battery, as small and hidden as possible. However, when choosing a battery, it is important to consider the regulator and the alternator: can my regulator handle the small battery? Mechanical regulators can be adjusted, electronic regulators have a certain range and can adjust the charging power within certain limits. If neither works, the regulator or even the alternator must be changed.

How do I find a suitable battery for my conversion?

When you have finished thinking about the conversion, it's time to choose. Our store will help you: with the dimensions of our batteries you can start making a tray or choose a ready-made tray from us. In addition, we list values for voltage, capacity and starting current for each battery, ... so you can decide whether your charging system harmonizes with the new battery.

I would like to have a lithium-ion battery. How can I enjoy it as long as possible?

LiFePo4 batteries used in motorcycles like to live in controlled conditions:

  • few of us ride at freezing temperatures, but the upper temp limit should definitely be considered if the battery is to be installed in the oil tank. No contact with the walls, leave enough space for cooling air to flow through, consider thermally insulating the battery.
  • Temperature limits also apply to plug-in charging. - Absolute maximum for regulator voltage: 14.6 V. Please remember that regulators can raise the voltage to over 15 V at higher speeds. This doesn't have to be the case, but we have seen original regulators that brought it up to 18 V - and at idle everything was ok. So if in doubt, measure it at high rpm as well.
  • If the bike is not used for a long time, check the battery voltage regularly. At 12.4 V or below it should be recharged. Modern speedometers and instruments on Harleys work on 12 V continuous current, as do the flasher modules. If you don't mind resetting the clock, consider pulling the main fuse or unscrewing the negative wire. By the way, Antigravity advises against leaving batteries on the charger all the time, even if it is a trickle charger. Please charge only with a charger that is also suitable for lithium-ion batteries.
  • Regular driving is the best thing you can do to your lithium-ion battery.
