Hey all - I didn't see a thread on this but my search has been a bit wonky, so my apologies if this is a known topic. Anyhow, I have two Ion batteries, one is junk and the other was smashed in a pressure ridge crash (holds charge but casing which holds battery to auger was broke). At $200 for a battery replacement, I'm not sure I want to go that route for a 6 year old auger. Are there any after market batteries people are using or mods to make other batteries work with the Ion?
