Charging LiFePO4, what’s the impact of lower voltages?

What voltage should I charge my LiFePO4 batteries? That seems like a simple question likely to have a single, direct answer. But, the actual answers are often unclear. Many LiFePO4 battery manufacturers recommend 14.6 volt absorption. But, that singular recommendation doesn’t account for numerous factors like managing a larger system, battery longevity, and more. Increasingly, we are seeing good reasons to lower charge voltages to 14 volts or below. But, what impact does that lower charge voltage have on capacity and charge time? Let’s take a look.

Update: Epoch’s 460ah battery, what we’ve learned

In January of this year, I published my review of the Epoch 460 amp-hour, 12 volt battery. My review was quite positive and reflected how the battery performed in my testing. But, once the battery was in the wild, reports began trickling in of troubles with some installations of the 460s. That lead to weeks of investigating the issues. At this point, I believe I have a solid command of what’s happening with these batteries and some of their limitations. While this better understanding of the batteries does serve to take a little shine off them, I still believe these are very solid batteries and capable of delivering excellent service. But, for best service, some tuning is required.


Seakeeper 1: installed, on the water, and stable

In the last year, Panbo(at) has had both Seakeeper Ride and now a Seakeeper 1 gyro installed. I know it may seem like it, but Panbo(at) didn’t have a stability problem before both products were installed. In fact, the boat’s ride impressed me even without any aids. But, now that it has these two systems keeping the boat’s movements in check, I can’t help but marvel at how much better the boat rides. Seakeeper’s systems have taken a boat with good manners and made it dramatically better. That’s quite the accomplishment.


MIBS 2024: Dockmate DPS

Dynamic positioning systems (DPS) have been around for over a decade. But, until now, DPS has been a feature of joystick control systems tightly coupled with propulsion packages. So, a boater interested in adding DPS to their boat couldn’t unless their existing engine and control package offered it. Typically, that means pods or recent outboards. That propulsion integration means if you own a boat with traditional inboards, shafts, and props, there very likely isn’t a viable DPS option. Until now! Dockmate now offers DPS as an add-on to any twin-engine boat fitted with their remote control.
