Hey everyone. Maybe this should be in off-topic, but it's about batteries so I thought it would be ok here.
For half the year I live on an island 18 miles off-shore. I don't have electricity out there and I don't want to set up a solar system or anything like that. I wouldn't need alot of power, but I would like to be able to charge electronics, use a lamp, charge my vape gear, etc. I was thinking that I could rig up a power bank with 18650s that would last me a week. I go to the mainland for a day about once a week and I would like to bring the battery bank with me back and forth. I would charge it on the mainland and bring it back out to use the power. I'm thinking it will be around 30 cells to make the pack, but I haven't put pen to paper to figure out just how much power I will need.
So my question is, what would be the quickest and safest way to charge the pack? I've heard Mooch talk about direct voltage charging or something like that. What is he talking about?
If anyone has any links or could point me in a better direction that would be appreciated. Everything I came up with on google was either for single cell power banks or huge 18650 power walls with a computer hooked up and everything permanently mounted.
