Premium Members Benjamin Treplin Posted November 30, 2004 Premium Members Report Share Posted November 30, 2004 I have the datasheets on both if you want me to send them to you. Hi Charles, I'd love to have a look at both. Robin, no worries, learned something new. What would be the effect on Ni-Ca on the long run?

Premium Members RobVanGelder Posted November 30, 2004 Premium Members Report Share Posted November 30, 2004 Thanks, Charles, I will do a search for them, though it might be that I already have those Schottky type of Diodes. Quote Link to comment Share on other sites More sharing options...
RobinThwaites Posted December 1, 2004 Report Share Posted December 1, 2004 Hi Benjamin Actually the effect on NiCads can be quite quick and terminal. The great thing about them is the low internal resistance and high current output, unfortunately this means that one pack can try to charge the other at a very high rate causing overheating, cell destruction and potentially fire and expolsions. I have been in the same room as a 7Ah lighting pack when the fast charger faulted and did not switch off. Half of the pack literally flew over my head and landed 6 feet away. I should stress that this is not a common occurance and unlikely under normal use but those diodes are important if you are going to parallel the packs.

Premium Members charlesneufeld Posted December 1, 2004 Premium Members Report Share Posted December 1, 2004 Hey Guys, I figure I will just post the links here instead of filling up your mailboxes with PDF's... :) http://www.onsemi.com/pub/Collateral/MBR2030CTL-D.PDF http://www.irf.com/product-info/datasheets/data/20ctq.pdf On the TO-220 package, pins 1 + 3 (Anode) have to be tied together to get the current rating... pin2 is the Common Catode to both diodes. That shoud get you started, ;) Rob, if you want these and have trouble getting them to your part of the globe, let me know and I can regular-post some your way. If you have any questions, just ask! ~Charles Quote Link to comment Share on other sites More sharing options...
Premium Members Stephen Murphy Posted December 9, 2004 Author Premium Members Report Share Posted December 9, 2004 BTW Stephen do you have a pic of the lok-on 20 NiCad? There is nothing on the PAG website.Best <{POST_SNAPBACK}> hi Benjamin, heres that photo i promised. Quote Link to comment Share on other sites More sharing options...
Premium Members Howard J Smith Posted December 10, 2004 Premium Members Report Share Posted December 10, 2004 Hi Stephen How are you? Just so you know (and also all other MK-V customers - hi) The MK-V D-Box (lower J-Box) has full protection and diodes to allow you to use all different battery types at the same time, flat & fully charged at the same time are no problem as well. Hope this helps All the best Howard :D Quote Link to comment Share on other sites More sharing options...
Premium Members Benjamin Treplin Posted December 10, 2004 Premium Members Report Share Posted December 10, 2004 Hi Stephen, thank you for the photo. Hi Howard, What kind of diodes do you use? How about voltage drop of these diodes. Best Quote Link to comment Share on other sites More sharing options...
Brett Manyluk Posted December 26, 2004 Report Share Posted December 26, 2004 Right, good day, eh? Here in the blustery Great White North Li-ions go down HARD when the temperature drops. Perhaps those of you shooting in moderate climates don't see much change, but the good 'ol nicad outperforms li-ions when the temperature gets below -20 celcius, and very much more dramaticly below -40 celcius. If you're in LA or Australia, this probably will not be an issue untill the next ice age, but if you'e a liittle farther north and you shoot in snow for any length of time, go for the big Anton Bauer nicads. Now, I should specify that the li-ion info is gathered from working with Sony and IPX batteries and not the Pag system or Anton Bauers. I would hope their performance is a little stronger. I run propacs, trimpacs, proformers in all sorts of combinations on my sled and they muscle through the cold weather rather well (especially considering they are all well-cycled batteries). My 2 cents is enjoy the li-ions on warm days or inside, and keep big ni-cads ready for 435 work, and igloo drama. Take off, eh...

Premium Members Justin Painter Posted June 2, 2006 Premium Members Report Share Posted June 2, 2006 I wondering if anyone has used the Anton Bauer Dionics with the arri 435. Will they turn over the 435? If not wich type will turn the 435 over. Thanks justin painter Quote Link to comment Share on other sites More sharing options...
Premium Members Justin Painter Posted June 2, 2006 Premium Members Report Share Posted June 2, 2006 Sorry people! I should of done a search before I posted this question. I think I figured it out thanks justin Quote Link to comment Share on other sites More sharing options...
Premium Members Brad Hruboska Posted June 3, 2006 Premium Members Report Share Posted June 3, 2006 Yeah the dionics just don't like the current draw with the 435 running over 60 FPS. I have had to keep some NICAD cells just for this camera, pity, cuz the dionics are really wonderful in almost every other application. They will shut themselves down to avoid a problem, as they are a SMART battery technology. ;) Quote Link to comment Share on other sites More sharing options...
Premium Members Michael Stumpf Posted June 23, 2006 Premium Members Report Share Posted June 23, 2006 I've used the Dionic 90's for about a year and a half now, but in that time haven't had to use the 435 more than 2 or 3 times. Each time I've never had to go over 48 fps, and it wasn't a problem. Now that I no longer carry any Proformers, I guess I better pick up a few Trimpacs for the time when I do need to use the 435 above 60 fps if that's the case. I wonder if one Trimpac and one Dionic 90 work okay together on the 435 or will it require flying 2 Trimpacs? So is this in fact the case that the Dionic 90's won't turn the 435 faster than 60 FPS?

Chris Banting SOC Posted August 18, 2006 Report Share Posted August 18, 2006 I was running a 435 at 72fps yesterday, and ended up having to hardwire into the belt belt battery just to get the camea up to speed. Luckily, I was hard mounted on a western dolly and camera jeep for most of the shots, giving me more control. I will definitely be needing to purchase some Trimpacs just for the 435 for use on my Pro II sled. Quote Link to comment Share on other sites More sharing options...
Premium Members WillArnot Posted August 21, 2006 Premium Members Report Share Posted August 21, 2006 My standard batt setup on my XCS sled is 2 x Dionic 90 and 1x Proformer. The Dionics have great longevity as we know, but the NiCad is there to handle any large amp spikes like the 435 demands. This has proven to be a winning combination at 120 fps +. It may also be the superb linear power distribution of the XCS battery managment technology. Will Quote Link to comment Share on other sites More sharing options...
Premium Members Edgar Colon Posted August 24, 2006 Premium Members Report Share Posted August 24, 2006 Since I have a good stock of Proformers I just bought 4 Dionics (for a start) Use 1 D for the monitor and 2 P for camera and aks. I have a Pro Sled. That set up works great for me with all cameras including of course the almighty 435. Edgar Quote Link to comment Share on other sites More sharing options...
