Hello
https://www.ebay.com/itm/High-Volta...ar=472050016599&_trksid=p2057872.m2749.l2649
I have the LiGo batteries from Grin and would like it to power the existing dynamo light on my bike as they seem to work fine, a Busch and Muller 6V light. I have bought some USB DC converters that ran 5, 9 and 12 V from a powerbank into the light. 9 and 12 V both produced the same level of brightness. The one from ebay i listed I got a 6V, and it's not as bright as 9/12V. I plan on gettiing the 9V version of the listed DC ebay buck converter
My question is, how do you waterproof something like the ebay converter? With the USB ones, it's all contained within the molded shell and I can cover it with electrical tape or perhaps silicone grease or silicone tape, but with the buck converter from ebay it's all exposed, and I'd like to cover it up in something like how the phase runners from grin are, or something similar.
Additionally I'd rather not use the USB ones, as it means it'll need a 5V battery source (or run the Grin 72V buck converter from the LiGos), but it's definitely something I could do
I couldn't find a buck converter that goes straight from 72 nominal battery (or 84+ for fully charged) down to the 6-9 volt range; that is also molded or covered. There are a bunch at 12 V though, but after experimenting with the USB DC DC converters, I found that there was no difference between 9 and 12 V, and I suspect there is an internal circuit in the light that prevents excessive current flow and indeed, I somehow shorted the light with a multimeter and it would not function until the capacitors running the standlight fully discharged overnight
