Victron’s Venus OS on a Raspberry Pi, install and configuration

The Victron Remote Management (VRM) portal and their Venus OS monitoring software deliver best-in-class access to information about your boat (, RV, or fixed solar) electrical sytem. But, running one of these systems has typically required Victron hardware which starts around $300. Victron has a long history of embracing the open-source community and they’ve continued that effort by supporting Venus OS on a Raspberry Pi. But, many people hear Raspberry Pi and either think dessert or that it’s over their heads and too complex. This guide walks you through the steps required to get Venus OS up and running on a Pi and sending data about your electrical system to VRM.

Discover Battery’s Lithium Blue LiFePO4, a premium drop-in

Discover Battery has been in the battery business since 1949, so they’re not new to the challenges of building batteries. They’ve recently begun distributing their Lithium Blue LiFePO4 battery in the U.S. and I’d say their experience shows in the quality of the product they’re delivering. Let’s take a look at what these batteries offer and how they’re different from what’s already available.

Victron RV upgrade, MultiPlus inverter especially

My family and I are getting ready to escape the Florida summer heat and visit friends and family we haven’t seen in much too long. Our trip’s mix of stops means sporadic availability of shore power, and that makes for great testing opportunities. I’ve been planning to install my DIY LiFePO4 battery to get some real-world testing in. But, to test any LiFePO4 battery, I needed to ensure the inverter and charger systems would coexist nicely with lithium chemistries.

DIY LiFePO4, build completed and testing underway

My first installment of this series introduced my build of a 280 amp hour LiFePO4 battery using cells purchased from China and a 120-amp battery management system (BMS) from a reputable U.S. supplier — though the BMS is still made in China. I left off in the very early stages of the build while I was giving the cells an initial charge to get them ready to join into a 12-volt battery. Although the process took longer than expected, it’s done and I’ve made a 12-volt battery. But what about the big question of capacity and performance of this homemade battery? I’ve got some early answers…

DIY LiFePO4, the build begins

In the last couple of months I’ve installed two of the three main types of lithium iron phosphate (LiFePO4) batteries. In March I installed Mastervolt’s system integrated MLi batteries on Have Another Day and just last week I finished up the installation of Battle Born’s 8D drop-in batteries on another boat. With two out of three types covered I figured it was time to get my hands dirty with the third type, a do-it-yourself build of a 12-volt battery from four cells and a battery management system (BMS).
