Markus, Can you help me understand more of your use of NP-style NiCd with the 435? I have been working with Panavision using our Li-Ion ENDURA batteries in series (to obtain the required 24V+) for the 435. When ramping up the 435 to high frame rates we have seen inrushes as high as 14 amps. Can you briefly explain the configuration when powering the 435 with your NiCd NP's? How many batteries must you use? Are they configured in series to handle the 24V? Thank you in advance for your help. I'm still learning about film cameras and appreciate any knowledge you can pass on. Best regards, Barry

Osvaldo, Thank you so much for the kinds words about IDX and our Li-Ion products. I would enjoy speaking to you about your experiences using our products. Please call me sometime. (310) 891-2800 Regards, Barry

Gentlemen, Li-Ion batteries do not get re-celled for the following reasons. 1. The cases are hermetically sealed and breaking or resetting the case will no longer meet safety regulations. 2. Each battery cell inside the pack should be matched and balanced to each other. Then a PCB is attached and programmed appropiately for manging each cell in realtime. So what I'm saying is by the time you replace the case, cells and reprogram of the PCB there would be no cost savings. Additionaly the comment regarding life of Li-Ion is not acurate. Generally NiCd and Li-Ion are rated at 500 life cycles, where NiNH is rated at 250-300 based on the manufacturer. Because Li-Ion has no memory effect and if cared for properly, you will see better than 500 cycles. IDX has manufactuered 14.4V Li-ion battery systems for over 8 years, the longest of anyone. Our pricing is extremely competitive and I'm sure you'll find the best return on your investment using IDX systems. We would ask for your consideration during your next purchase?

Hello Gentlemen, First, please note that I do work for IDX and have allot of experience with the Varicam. The Panasonic Varicam has very high inrush when powered up. Protection circuits inside Li-Ion batteries must be programmed properly. The Varicam generally draws about 38W on its own, but spikes much higher on power up. The Evertz unit I believe draws about 10W. Were you using on-board lights at the same time? All batteries have a high load limit, but Li-Ion is programmed based on length of inrush. Not all Li-Ion batteries are programmed the same from each manufacturer. I am more than happy to discuss this in further detail and I can be reached at barry@idx.tv or 310-891-2800. We have a few Steadicam owner/operators who have converted to our IDX Li-Ion ENDURA System and you will see more activity from both Tiffin and George Paddock Inc regarding the use of our systems. We would ask that you investigate IDX ENDURA System products when you get a chance. IDX has been manufacturing Li-Ion power products for over eight years and have more systems in use worldwide than any other manufacturer. Again, should you like to discuss these issues further, please do not hesitate to contact me directly. Best Regards, Barry Rubin General Manager IDX System Technology, Inc. www.idx.tv
