Hey guys .with these diodes where do you connect your lvd is it before or after the diodes .If it is before the diodes you would require 2 lvd's .one for each battery.If after then you would need a adjustable lvd to set the cutout voltage? .I gather with the 2 batteries connected this way that the batteries drain evenly as if they were hooked together but don't have the problems .

I have standardized on one part, the 122NQ030R made by International Rectifier / Vishay. The datasheet is here: <www.vishay.com/docs/93210/93210122.pdf> This Schottky diode has an extremely low forward voltage drop, and it can handle 120 amperes. I generally use the "R" suffix version, where the mounting foot is the anode and the 1/4-20 screw is the cathode. I mount the diode on a short piece of copper bar, which is then bolted to the positive terminal of the power supply. This allows me to float the battery on an Astron power supply, but prevents backfeed if the AC power fails. Digi-Key sells this item for about $24 apiece. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Mike Dietrich Sent: Saturday, August 02, 2008 3:18 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: Dual battery system any idea of a part number for this type schotky diode for this purpose? mike
