Upgrading to lithium batteries & testing an all Mastervolt DC power system

Like many boaters, I treasure the peace of a serene anchorage, but not the sound and smell of a generator. So the high energy density and fast charging abilities of lithium batteries got me interested, and eventually led to an all-Mastervolt system that should also improve my 12-volt DC house power system in many other ways. This is part one of a series detailing the reasons for that decision, the installation, and how well it performs.

Lost Bens? Nope, we’re in the lithium mines, finding gold!

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…

Upgrading our house battery system, part 2; life is better with lithium

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.

Lithium battery math, better than you may think

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.

WeeGo_Jump_Starter_Battery_Pack_Pro_cPanbo.jpg
Most boaters will not experience the benefits of a Lithium Ion main battery bank any time soon, but nearly instant gratification is possible with a portable Li Ion charger pack, some of which can even jump start a small diesel engine. Brands and models are proliferating like fruit flies, but I’m particularly keen on the WeeGo Jump Starter Pro above, which I’ve been testing for a couple of months. It is a veritable Swiss Army knife of an on- or offboard power source…

Volvo Ocean 65, powered by Mastervolt Li Ion

VOR_65_power_overview_courtesy_VOR_Roman_aPanbo.jpgI’m happy as an oyster slow cruising Chesapeake Bay with my favorite first mate, but if I had a teleporter I surely would have jumped on an invitation to check out a Volvo Ocean 65’s systems in Newport yesterday. I doubt I would have encountered a scene as tidy as the photo above — which looks forward in the main cabin of Dongfeng with most of the engine, power, battery, and keel ram covers removed, as well as the pedestal galley — but then again all that technology has now zig-zagged almost around the planet in often demanding conditions. There’s a lot of gear on these one-design racers that has performed impressively, as best I know, but I’m particularly taken with the Mastervolt Lithium Ion battery system…

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).

A guide to understanding boat batteries part 1, lead-acid

Earlier this year, unfortunately, we roasted the 1,855 amp hour battery bank needed to achieve electrical nirvana on our 40-foot trawler Bliss. And that meant a painfully expensive and unbudgeted replacement, plus a period of no lights, no engine, and no electric toilet. So having recently suffered through the battery selection process, I’d like to share in depth what I know about the multitude of deep cycle high-performance battery choices…
