In this video, I'll show you how to replace Ni-Cd batteries with Li-Ion batteries, which need protecting. Specifically, I'm giving my old drill new life.
<p>Nice! Definitely gonna make it!</p>
<p>Be positive and constructive. OK. Please change the title to &quot;How I physically replaced these round tubes with those round tubes and also added a cool digital display black box thingy.&quot; 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.</p>
I used 5 li ion 2600mah samsung cells on an old battery drill. however now if i pull the trigger quicky or if i subject it to any load it just stops working. Any ideas?
<p>I'm guessing that is because of the over current protection</p>
<p>Can you charge them on the old charger and just monitor the lipo alarm to check how much charge they have?</p>
<p>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.</p>
<p>I need to do this with my work drill!!!! Perfectly good just abysmal battery life.....Could you post the link to your lipo protection circuit on eBay. I can't find anything like it on eBay AU</p>
Just search for &quot;lipo alarm&quot;, and you should have plenty to choose from. :)
