   As part of our ongoing development of jcx, we are trying to settle on some options for rechargeable batteries. At Toys R Us there are standard 9.6V NiCd battery packs such as Nikko #1299 with a standard size and connector. The size is about 100 x 55 (...) (23 years ago, 30-Jul-01, to lugnet.robotics)
   
        Re: rechargeable 9V battery packs for RCX/JCX and Legos motors —Brian Alano
     I use mostly use Rechargeable alkalines in my RCX. Sometimes NiMH. Never NiCd. A lab might get the best mileage out of NiMH since they seem to care least of the rechargeables about whether they get discharged to much (alkalines) or too little (...)

     (...) I would like to follow up on this. The school I volunteer at to teach LEGO Robotics now has 4 RIS 1.5 and 4 RIS 2.0 and batteries are a real problem. Disassembling kids robots to change batteries is a pain! I have been using 1800MAh NiMh AA (...) (23 years ago, 10-Sep-01, to lugnet.robotics)

      (...) You might want to consider the connector used for R/C battery packs. If memory serves, they are fairly immune to shorting, can only be connected the right way, and the connectors lock together. My digi-key catalog shows Molex as one possible (...)

        Re: rechargeable 9V battery packs for RCX/JCX and Legos motors —Robin Malton
   Didn't someone recommend a rechargable power pack designed for radio controlled model cars once - I saw a web page with this on, but can't remember where. Great if you have a RCX 1.0 - still available from education suppliers Robin "Bruce Boyes" (...) (23 years ago, 31-Jul-01, to lugnet.robotics)

   While we're on the subject, I just got an RIS 1.0 on e-bay, and I'm wondering what is the best power supply for the RCX? The one listed on Lego-Dacta says, "Not Available." -- Russ -----Original Message----- From: news-gateway@lugnet.com (...) (23 years ago, 31-Jul-01, to lugnet.robotics)
