What kind of charger does a lithium ion battery use?
Lithium batteries require a Constant current/Constant voltage (CC/CV) charge type with simple Bulk, Absorption, Float stages. Many lead acid chargers have desulphation and equalisation stages built in, which will pulse high voltages of 15.3-15.8V into the battery.
Does it hurt to turn on a fish finder out of water?
It is not recommended to run a FishFinder and transducer on a boat that is not in the water as you will not get any readings from the transducer.
Can you use 2 fish finders at the same time?
Any time you run two units with the same frequency there is a risk of interference. However, with the modern noise rejection systems built into today’s fish finders, in most conditions when there is a unit on the front and back of the boat with the same frequencies, they will not interfere with each other.
