I have a Vistalite NSP Hyp 15 light that has two of those long, heavy, battery sticks. The light is a few years old and will need battery replacement at some point. I really don't like the batteries that Vistalite supplies. I have seen battery packs unsed for a lot of other appliacations. What I am wondering is, can you make up a battery pack out of C or D cell NiMH batteries and come up with the voltage or amperage that is needed to run this 15 watt light for a couple of hours. I don't know how to calculate what would be needed to do this.
Let me know if this is doable and if so how to do it.
Thanks for any help.
