Description
Motorcycle Battery Eliminator / Charging Capacitor. Allows the engine to be kick started even with no battery.
This battery eliminator (charging capacitor) allows compatible motorcycles to run without a battery, using the generator alone. It’s a popular upgrade for track, MX and enduro bikes, where simplicity, reliability and weight saving matter more than creature comforts.
Built around a rugged, long-life capacitor, this unit is designed to handle the high ripple currents and voltage surges found in motorcycle charging systems. With more capacity than many similar-sized units, Rex’s battery eliminator allows kick-starting on suitable systems.
Supplied complete with mounting clip, cable tie and connectors for a clean install.
What it does (and what it doesn’t)
Allows battery-less operation on suitable generator/ignition systems
Saves weight, even compared to lithium batteries
Zero maintenance
Can be left unused for long periods with no damage
Ideal for track, MX and enduro bikes, with or without power valves
Important limitations
Electric starters will NOT work, no battery = no stored power
Not suitable for ABS or fuel-injected motorcycles
Lights will pulse at idle and improve with engine speed
- Indicators will often be a problem where no battery is fitted
Not recommended for road bikes, if the engine stalls at night you are left without lights.
This unit does not generate power. All power comes directly from the motorcycle’s generator, so at idle you’ll see natural voltage pulses, this is the engine slowing down on compression and speeding up as it fires. As revs rise you stop noticing this effect, lighting and power valves behave normally. When you remove the battery you also remove the bike’s reserve power source, NO battery eliminator can fill in for the charge held in a battery, despite what others may claim.
