    Be positive and constructive. OK. Please change the title to "How I physically replaced these round tubes with those round tubes and also added a cool digital display black box thingy." to better reflect the content. The title is deceptive and makes one think they might learn something about the issues around replacing NiCd with LiIon.

    Can you charge them on the old charger and just monitor the lipo alarm to check how much charge they have?

    this was just what I was looking for. I'm swapping out the old and dead NiCads for Lithium Ions on a Colman Emergency Lantern. If you wouldn't mind would you explain why you bypassed the electronics on the NiCad Charger? My lantern has a 5.3 volt 1amp wall charger, and as an alternative a built in hand crank for end of the world emergency power when no other source of electricity could possible be found other than turning a miniature hand crank like a madman for 2 hours to generate a full charge of about 4 hours. I don't think I can bypass either charger given the construction of each. I could probably insert the tender from eBay though between batteries and electronics. What do you think? Any thoughts would be greatly appreciated.
