JMT HJTZ7S-FP-SWI Lithium Ion Battery | Ref: YTZ7S, YTX7L-BS, TTZ7S


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 will not be damaged when the motorcycle is cleaned with high pressure.

Indicator (I)

All batteries are equipped with a battery condition indicator.

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

Replacing a standard lead-acid battery with a JMT lithium-ion battery can save up to 5 kg in weight without any significant effort.

The following advantages speak for JMT lithium-ion batteries:

- approx. 1/3 of the weight of the comparable lead-acid battery

- unbeatable cost/weight saving ratio

- can be installed in any position, as it contains no acid

- contains no heavy metals

- balanced discharge/charge of all cells by balancer

- fast charge with high charge 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 60C

- safe technology and long service life

Lead-acid batteries can only use 30% of their capacity due to their specific characteristics,

whereas lithium-ion batteries can use almost 100% of their capacity.

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

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

With the help of adapters, the dimensions of the lithium-ion batteries correspond to the dimensions of the original lead-acid batteries.

The connections are also identical, which is why 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 desulphate deeply discharged batteries below 10 volts with a voltage in excess of 14.9 volts before commencing the actual charge.

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

The manufacturer guarantees sufficient starting capacity down 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 cannot burst into flame or explode during normal operation.

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

- 12 V maintenance-free lithium-ion battery

- charging current recommended 1 A

- maximum charging current for fast charging 12 A
