Great ideas
I live in the tropics near the coast and it’s around 30 degrees Celsius here most of the year and very humid. Steel rusts very fast and electronics don’t last long here.
I would love to try high capacity Li-ion batteries but I read that they don’t last long in these conditions.
I need something simple, solid, rugged, shockproof, waterproof, dust-proof, under 50 Euros and hope to get 5 years life out of it before it gets consumed by the super aggressive, hot, salty, humid weather here. Maybe I should look for a diving torch even though I don’t dive?…
