Notice
Charge the battery only with a recommended LiFePo4 battery charger that uses a CC/CV charging profile and provides a maximum voltage of 14.6V and 50A. To ensure safety and reliability, always use battery cables of sufficient thickness with M8 tongue connectors or ANEN plug connectors to connect your trolling motor, and make sure to use a suitable fuse between the battery and motor. Do not use crocodile clamps to connect to the battery, as these can lead to heat development and damage to your trolling engine and battery. Please note that damage caused by unsuitable connectors or cabling is not covered under our warranty terms.
Please be aware that this battery is not suitable for use with caravan movers, as high peak currents can cause irreversible damage to the battery. For increased capacity, batteries can be connected in parallel, but always make sure that batteries are of the same type, age, and charge status before connecting them. Also, use cables of sufficient thickness.
Our batteries are rated splash-water proof according to the IP54 standard. While they can handle light rain and splashing water, they cannot be fully immersed in water or exposed to heavy rains. To prevent any problems, use a waterproof battery container or battery bag and position the battery upright on a slightly elevated level to avoid continuous contact with water. Please note that water damage is not covered under our warranty terms.
