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…
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).
The caption is serious, because right in front of your eyes is the most basic — and possibly dangerous — mistake anyone could make while setting up and bench testing a fully integrated lithium-powered marine electric power system. And it’s a mistake I made even though it was truly right in front of my eyes during the many hours I spent trying to figure out why Victron’s brand new and quite amazing Lynx Smart BMS would not power up. So if…
Whether on the water, in an RV, riding the trail, or operating a piece of industrial equipment, a dead battery will ruin anyone’s day. Veratron’s new VL Flex Intelligent Battery Monitor Kit contains everything needed to deliver real-time battery health and status to the smallest dashboard. It combines two pioneering products, Veratron’s award-winning Intelligent Battery Sensor and its revolutionary VL Flex Instrument. All additional components needed for a fast and easy installation are included.
Mercury Marine, a division of Brunswick Corporation (NYSE: BC), today launched SmartCraft Connect, which allows boaters to use Garmin and Raymarine multi‑function displays (MFDs) to access detailed information about the status and operation of their SmartCraft‑compatible marine engines.
Dockmate, manufacturer of wireless remote controls for yachts, announced today its next generation of receivers that are built with advanced hardware and communication features.
There’s probably no good time for a bow thruster to get stuck in ON mode, but it happened to me while backing into our marina slip on a windy day. Moreover, that maneuver included...
In part one of this series, I explained our motivations for upgrading to a lithium house battery bank, my choice of all Mastervolt components, and the pleasing results of early testing. Now let’s talk about what makes lithium different and what you need to consider if you too plan an upgrade. Active battery monitoring and control are critical to protecting other power components, for instance, and there are other important install details. Plus, I’ve got more real-world testing results to share.
There’s a lot of talk about installing lithium batteries in boats, but the enthusiasm often comes to a crashing halt when boat owner hears the cost. I’ve just installed a Mastervolt lithium system in Have Another Day and I’m over the price shock. But as I work to understand the results of my upgrade I’m amazed by the benefits I hadn’t anticipated. Follow along with my math and see if you reach the same conclusions I do about the benefits of upgrading to a lithium house bank.
Volvo Penta today announced the commercial availability of the industry’s first fully integrated Assisted Docking system. The system gives the captain better control when docking a boat by automating his or her intentions, compensating for some dynamic variables, such as wind and current, and helping the vessel stay on its intended course…
