I contacted Strike Master and they have discontinued selling the lithium Ice Force battery.
I do have the Electra 12000 and I can only drill about 3 holes with a SLA battery, when very cold, and 30″+ of ice. If the temps are above 20+ degrees and ice is under 24″, then I can drill about 20 holes.
I am wondering if those that have the lithium battery are getting more holes at the colder or warmer temps and at what ice thickness.
