Antigravity Small Case Lithium Battery

Why riders pick this for cramped installs

• Small case actually means smaller. Not just “scaled down” — the footprint and height are cut to avoid trimming panels or modding mounts.
• Lighter in the hand. You notice it when you carry the bike up the trailer ramp or tip the scales.
• Multiple cell options let you match the battery to the application instead of over-spec’ing and adding weight.
• Cleaner routing around the box — fewer clearance headaches with wiring, airboxes, and aftermarket parts.
• Holds up to regular use; once tucked in, it mostly disappears from day-to-day thinking.

Practical fit and install notes

• Check physical dimensions against your tray — small case helps but it’s not a guarantee.
• Polarity and terminal type matter; you may need a short adapter or different terminal on some frames.
• Use a compatible charger and follow lithium storage advice if the bike sits for long stretches.
• If the bike has an older charging system, verify charging voltages — lithium chemistry is less forgiving than lead-acid.
• For race or track bikes where every bit of weight and space counts, this is a common swap. For daily commuters, consider how you store and charge the battery.

Quality and build notes

Available cell configurations

• 4-Cell — ultra-compact and light; ideal for small bikes or minimal electrical setups.
• 8-Cell — lower capacity, lightest option; fits very tight spots.
• 12-Cell — middle ground for balanced starting and run time.
• 16-Cell — higher capacity for bikes with bigger electrical loads or frequent starts.
