Ultimatron lithium batteries - represent reliable and modern technology, and the batteries are excellently suited as a bow-mount trolling motor battery or a boat electronics battery. Ultimatron batteries represent LiFePO4 battery chemistry, whose advantages are efficiency, quality, high operational safety and long lifespan. The batteries have an integrated BMS system, which protects the battery cells from, among other things, over- and undervoltage. In practice, the BMS ensures that the battery's lifespan is as long as possible. The battery's charge level and momentary current consumption can be conveniently monitored with an iPhone or Android app. Thanks to remote readability, there are no restrictions on the battery installation location - it is enough that the battery is within Bluetooth range.
Amazingly light lithium and powerful! - The Ultimatron 12V 100Ah Lithium weighs only 11.5kg. That really is little, as a corresponding conventional lead-acid or AGM battery weighs approx. 30kg. When you also relate the lithium battery to its power class, you would already need a 200Ah lead-acid battery, which weighs over 45kg! You certainly don't want to carry this extra weight in your boat for nothing.
Ultimatron lithium batteries are manufactured in China, but a lot of time and resources are spent on their production and quality control, ensuring that all batteries are of high quality. The battery is manufactured to a high standard, and all parts inside the battery represent quality and fine finishing. This is also why Ultimatron batteries come with a five-year manufacturer's warranty.
The Ultimatron 12V 100Ah is an excellent battery for 55lb bow-mount trolling motors as well as for electronics. This battery provides power for even several days.
Charging the battery: Please note that lithium batteries should always be charged with the recommended charger. We recommend charging this battery with the Victron 12V 17A or 12V 25A IP67 charger, which is an excellent charger for charging and maintenance.
Bluetooth connection to your phone - You can download the Ultimatron application to your phone, and with it you can check, among other things, the voltage, the remaining charge as a percentage, the battery temperature, the general condition of the battery or even the number of cycles used, as the battery has built-in Bluetooth. A convenient additional feature that lets you make sure how much power is available for your fishing day or what the power consumption of your electrical devices is.
The Bluetooth connection works with the Ultimatron App on your smartphone
