Lithium-ion batteries from JMT, high-tech for your motorcycle.

Batteries of the latest generation recognizable by the red housing cover.

Spacer (S)

Battery is equipped with one or more spacers, which are glued under the battery with the supplied adhesive strip, so that the battery fits exactly into the battery box.


Waterproof (W)

The battery is completely waterproof and takes no damage when the motorcycle is being cleaned at high pressure.

Indicator (I)

All batteries are equipped with a battery condition indicator.

Just press the test button. If all 3 blue LEDs light up, the battery is fully charged (ful). If only 2 LEDs are lit, it is only half (med) charged. At the latest when only one LED is lit (low), the battery must be charged.


By replacing a standard lead-acid battery with a JMT lithium-ion battery, you can save up to 5 kg of weight without significant effort.


The following advantages speak in favor of JMT lithium-ion batteries:

- About 1/3 of the weight of the comparable lead-acid battery

- Unbeatable cost / weight savings ratio

- Can be installed in any position, as there is no acid

- contains no heavy metals

- balanced discharge / charge of all cells by balancers

- fast charging with high charging current possible (up to 90% in 6 min)

- very low self-discharge (max 5% per month)

- even at high temperatures still good performance up to 60 ° C

- safe technology and long service life

Lead-acid batteries can only use 30% of their capacity due to their specific properties.

while nearly 100% of the capacity is available for lithium-ion batteries.

For this reason, the lithium versions of the JMT batteries require only 1/3 the capacity of a comparable lead-acid battery for the same starting power.

A uniform state of charge of all cells is also ensured by a built-in processor ("balancer").

The dimensions of the lithium-ion batteries match the dimensions of the original lead-acid batteries using adapters.

The connections are identical, so the battery can be replaced in a few minutes without any further adjustments.

Please note that only suitable chargers may be used for charging. We recommend JMP chargers.

For the maximum recommended charging currents, please refer to the technical data below


Under no circumstances should chargers be used which attempt to desulphurate deep-discharged batteries under 10 volts with a voltage of more than 14.9 volts before they begin the actual charge.

The maximum charging voltage of 14.9 volts must never be exceeded.

The manufacturer guarantees a sufficient starting capacity up to -5 degrees Celsius.


JMT lithium-ion batteries use iron phosphate (LiFePO4) as the cathode material and use the lithium-polymer process in their manufacture.

As a result, they can neither go up in flames nor explode in normal operation.

The technology and the manufacturing process guarantee the highest safety standard for lithium batteries.

- 12 V maintenance-free lithium-ion battery

- Charging current recommended 1 A

- maximum charge current for fast charge 8 A
