In this video, we show you how various popular lithium batteries communicate critical data—like state of charge, voltage, and cell temps—via Bluetooth apps and wired connections to advanced monitoring systems like the Victron Ekrano GX. We walk through real-time demos of six battery brands (Victron, Epoch, SOK, Expion360, Battle Born, and RICH SOLAR), showcasing their app interfaces and how they integrate with Victron's monitoring ecosystem. You'll see how different systems relay info, which are more user-friendly, and what tradeoffs exist between Bluetooth vs hardwired setups. This is lesson 2 in our Battery Monitoring series, so be sure to check out the full playlist. ⚡️ Shop the Gear We Use - Everything you see in this video is available in our store — tested, proven, and ready for your next build at: 🛒 Shop Now: 🧰 Need Help Designing Your System?
