You mean I might not get the claimed performance?

He is selling some DIY experiment kits to make your own carbon battery that has a energy density comparable to lithium. <br /><br /><br />adminhttps://www.blogger.com/profile/17605162122677823581noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-29723994304450782932018-10-16T12:06:21.644-04:002018-10-16T12:06:21.644-04:00I bought mine in person at the Orlando hamfest las...I bought mine in person at the Orlando hamfest last year, and they were good as gold. Always possible they hired someone less good, but that's the same as anywhere else. <br /><br />I was thinking of doing a piece on those smart chargers, and the only thing I have against the CBA is that it's just a calibrated discharge. I'd need to do some research into what's out there now vs. what I have. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-70259070617001642202018-10-16T11:03:40.527-04:002018-10-16T11:03:40.527-04:00I need to buy one of those testers.

Amazon doesn't sell that model, but they have a bigger one for a hundred bucks more. <br /><br />Is this "West Mountain Radio" going to play nice with my credit card, I wonder?Malatropenoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-84861151312088854632018-10-15T23:10:30.337-04:002018-10-15T23:10:30.337-04:00Yep, absolute garbage.

I've seen brand-new connectors that were junk, while the used, dirty ones from the next table were milspec connectors for half the price.<br /><br />Once you find a good vendor, stick with them.<br /><br />We had an exceptionally good rechargeable battery vendor at the TRW swap I used to go to. NiCad Lady has been around forever, and only sold premium cells and packs that were 100% tested to the cell level.<br /><br />Never had a cell or pack from her that didn't exceed specs, and I was testing them carefully.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.com
