Power Queen LiFePO4 for Christmas

Hello Operators.
By now you’ve noticed the Power Queen LiFePO4 batteries I’ve been using in the Off-Grid Ham Shack project. I thought to go ahead and share their Christmas offers, to help y’all save some money, while supporting the blog/channel.

Remember, the batteries in this post are just a few of those available from Power Queen. Be sure to check out the regional sites, to find a suitable LiFePO4 battery for your project.

Introduction

No More Lead-Acid batteries!

We’ve discussed this on the channel and blog before, but it needs to be stated, then restated. Lead-acid batteries are a terrible investment for an off-grid station!

  • Relatively low cycle life means we’ll be replacing lead-acid batteries far more often.
  • Even with the “lower price” of lead-acid, we would have been through ~8x lead-acid batteries before our first LiFePO4 equivalent even thinks about getting tired.
  • ~50% of stated capacity means we’re only getting about half the storage capacity we expect from a lead-acid battery. 100 amp hours means 2x 100 amp hours lead acid batteries in parallel (food for thought).
  • Peukerts Law shows us the diminishing capacity of a lead-acid battery, as the load increases.
  • LiFePO4 batteries provide nearly 100% depth of discharge without damaging them.
  • LiFePO4 batteries don’t vent toxic fumes into the air. This means they can be located inside the station, without harming the Operator.

There are lots of benefits to LiFePO4 compared to lead-acid. Performance, capacity and cost-savings over the lifetime of the battery are the most important. The only downside to LiFePO4 is below-freezing charging. This is one reason for the diesel heater in my ham shack. Still, lead-acid batteries are great for starting engines. I can’t imagine many other applications where I’d use them over a LiFePO4 battery.
Food for thought. OK, let’s get started.

Battery Storage

In an off-grid solar system, a battery acts as a reservoir, storing the energy produced by our solar panels for later use. This stored energy can power our electrical devices in real-time, when there is no sunlight, or provide additional current when current from the solar panels is insufficient. The battery is like the fuel tank in our cars. It allows us to store the solar energy collected during the day, so we can use it when we need it. The battery in an off-grid system, ensures continuous and uninterrupted power, independent of the grid.

This is the smallest “big” battery on offer from Power Queen. It is a 50 amp-hours, 640 watt-hours with a 50 amp max current load. If you’re on a tight budget, but still wanting to get your station off-grid, this might be the way to go.

Keep in mind, Power Queen batteries go together like Lego blocks. You can start with one, and add additional batteries are your station grows.

For those operators wanting to run inverters in their off-grid cabin, overland vehicles, campers or RV setup, a 24 volt battery might be an attractive option.

If you’re converting your solar power to AC with an inverter, the higher voltage battery will supply energy to the inverters more efficiently. This means dealing with RFI from our inverters in our radio, but this might not be a big problem if your radio gear is used periodically.

This is a 200 amp hour, 12.8 volts LiFePO4 battery. It is the equivilent of having 2x 100 amp hours LiFePO4 batteries from the off-grid ham shack, in parallel.

If you’re getting serious about your off-grid solar storage in the UK, this pack might be worth taking a look at.

Charge controllers

If you’re running a 12 volt system for your ham radio station, I will always suggest the Genasun series of radio-friendly charge controllers, to keep your Power Queen LiFePO4 batteries topped up. A solar charge controller, also known as a solar regulator, is a critical component in a solar power system. Its main function is to regulate the flow of energy from the solar panels to the battery/batteries while preventing overcharging or damage to the solar storage system. Don’t let anyone tell you a charge controller is not required!

The solar charge controller is the first and last defense in protecting our battery. Here’s how:

  1. Current Regulation: When sunlight hits the solar panels, the panel will generate direct current (DC) electricity. The charge controller helps regulate (or limit) the amount of current from the panels to the batteries. It ensures that the batteries receive the appropriate charging current, preventing the battery from being overcharged, or charged at too high current.
  2. Battery Protection: Solar charge controllers monitor the battery voltage. The charge controller will alow charging when the battery voltage is within certain voltage limits. It will also prevent charging of the battery, if the battery is full. These features help protect the battery from excessive discharge, and inadvertently oversharging our battery. Both scenarios can lead to damage or reduced battery life.
  3. Preventing Overcharging: As mentioned above, overcharging can damage the batteries and reduce their lifespan. Solar charge controllers use a technique called pulse width modulation (PWM) or maximum power point tracking (MPPT) to prevent overcharging. PWM controllers (Bad!) regulate the charging voltage by pulsing the current flow to the batteries, while MPPT controllers optimize the solar panel’s output voltage to deliver maximum power and adjust the charging parameters accordingly.

Final thoughts

For nearly half a year at the time this post was published, the Power Queen 100 amp-hour, 100 amp max load LiFePO4 battery has served me well. It has done such a great job that I now have a second one for a total of 200 amp-hours of solar storage in my off-grid ham shack.

It has been an almost impossible task finding a LiFePO4 battery manufacturer who services many of the markets where my content is consumed. Add the requirements of good customer service and product quality and the field gets thinned out pretty quickly. As I’ve mentioned already, so far so good with Power Queen. If that changes, I’ll certainly update you all.
