questions on how to power a fish finder.

Many different options and opinions about batteries.

Lead acid SLA Battery: Found anywhere, cheaper, heavy

Lithium Ion Nocqua battery: Compact lightweight, Has been popular lately, More expensive, 500+ charge cycles.

Lithium iron Phosphate battery (Bioenno): 50-70% the weight of SLA battery, More expensive, is capable of 2000+ charge cycles.


I personally use the Bioenno battery and find that it charges fast, lasts long and is very reliable. It's an investment like everything else but you will be pleased years into the future when your battery still works well.
