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

Length: 134 mm
Width: 65 mm
Height: 93 mm

Weight 0.96kg

The following advantages speak in favor of 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 they contain no acid
- contains no heavy metals
- balanced discharge/charge of all cells thanks to balancer
- fast charging with high charging current possible
- very low self-discharge (max. 5% per month)
- good performance even at high temperatures up to 60°C
- safe technology and long service life

Due to their specific properties, lead-acid batteries can only use 30% of their capacity, whereas lithium-ion batteries can use almost 100% of their capacity.

For this reason, the lithium versions of the JMT batteries only require 1/3 of the capacity of a comparable lead-acid battery for the same starting power.
A built-in processor ("balancer") also ensures that all cells are evenly charged.
The dimensions of the lithium-ion batteries correspond to the dimensions of the original lead-acid batteries with the help of adapters.
The connections are also identical, which is why the battery can be replaced in just a few minutes without any further adjustments.

Please note that only suitable chargers may be used for charging. We recommend JMP chargers.
Please refer to the technical data below for the maximum recommended charging currents.
The use of a charger with a voltage of more than 14.9 V to charge a deeply discharged battery with less than 9.6 V is not permitted.

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

Technology

JMT lithium-ion batteries use iron phosphate (LiFePO4) as the cathode material and use the lithium polymer process in their manufacture.
This means that they cannot burst into flames or explode during normal operation.
The technology and manufacturing process ensure the highest safety standards for lithium batteries.
