Our new batteries/rechargeable batteries feature the latest generation of lithium cells as well as a state-of-the-art printed circuit board with advanced protecSAFE-Mosfet technology, which no other battery offers. This makes them not only the safest and most reliable, but also the strongest. They are equipped with the most advanced monitoring system that prevents total discharge, overcharge, overvoltage and thermal overload.
In addition, a 70A fuse against short circuit protection was installed and can be replaced, which only uses Ultrabatt. The Ultrabatt multiMIGHTY battery/accumulator weighs only 456 grams and is as powerful as a conventional 16 Ah lead battery.

We use a lithium-ion battery with a capacity of 4Ah in all our conversions with consistently very good experience. The lithium-ion batteries are able to use almost 100% of their capacity, while the lead-acid batteries, due to the specific characteristics, only 30%. Consequently, the Ah value cannot be compared 1 to 1.
For vehicles with higher compression, extensive electrical equipment or vehicles that are often used in the cold season, we recommend the use of 5 Ah or 6 Ah LI batteries. The cold is also still a condition in which the lithium-ion batteries lose power. If a bike is standing in a cold garage during the winter, you will feel loss of power during starter operation. If a motorcycle stands in the warm, even with long breaks in operation, the engines start as if the battery had been charged shortly before. In general, battery fresheners or chargers with low charging currents are still a good measure during longer breaks.
We install the lithium-ion batteries, without any further modifications, in the old bikes, i.e. also in all our BMW Boxer 2-valve models. The prerequisite is, of course, that the charging system is in order. What the LI batteries do not tolerate at all are too high charging currents above 14.5 volts. Such high voltages can occur with a defect of the charge controller or by charging with unsuitable chargers that work with fast charging or pulse currents.
