James, is there a battery management system built into the Lithium Ion from Ice Force? Meaning, will it completely go dead or is there some type of reserve system to prevent this and allow for overall longevity (cycles) out of this battery?
Sorry. I will readily admit that I’m a bit of a nube when it comes to battery chemistry and design so I don’t have an answer for your particular question.
Most lithium batteries that I tested did NOT do well in the cold resulting in very short run times in much the same way guys ran into issues powering augers with Lithium batteries last winter. Their augers worked well when the battery was warm. When it got cold… not so much. I think it goes without saying that most of us can expect it to be cold when we ice fish so this was a primary concern during testing.
I tested the Ice Force battery at very low temps without any perceivable performance issues. Will the Ebay battery linked above work well? I don’t know. I didn’t test that particular battery brand so I couldn’t say one way or the other.
