    How do you pass-through cables on a vehicle system that's not permanent?

    I have a van that's a daily driver but also our tow vehicle when we go on long trips with our squaredrop camper. Right now, the whole power system and solar array for it are mounted in/on the camper. I have a cable inlet in the side of the camper that allows me to bring the solar panel cables...

    Did I get scammed with counterfeit Victron equipment?

    I ordered a bunch of Victron parts from Amazon and the first of it showed up today. The SmartShunt and GX Touch 50 showed up in generic white cardboard boxes, no branding at all with less internal organization than I expected. I've never seen Victron stuff in anything other than Victron-blue...

    How can you ship LFP Returns since they're HAZMAT

    I need to ship 4 208Ah cells back to the US vendor since they want to exchange them to resolve a problem I'm having. However, LFP cells are HAZMAT, right? How can I, as just a normal end user with no HAZMAT cert, ship the cells back? I figure at least some of you have had to do this before and...

    I just purchased 4 280Ah LiFePO4 cells. I'm trying to top balance them by the method favored by this forum. I have a Volteq HY3030EX power supply that I'm using to charge/balance the batteries. A year or two ago, I lent the power supply to someone who ignored my warnings about what not to do...

    Thoughts on Hyundai HiD-S300RG(BK) Panels?

    There's a place near me liquidating new-old-stock Hyundai HiD-S300RG(BK) panels at $183 plus tax. Since I can just go pick them up without any freight cost, that make their cost per watt better than the SanTan used panels Will did a video on. If I get them, I'd be using them to add an additional...

    Is it reasonable to buy Lishen cells off AliExpress right now?

    I'd like to make a 280Ah 12V-nominal battery for my camper based off Will's video about the Lishen cells but with an Overkill BMS instead of the Daly. However, I see some chatter on here about a particular Lishen buy taking half a year for delivery. If I use the link that Will put in the video...
