Enjoybot 12V 100Ah LiFePO4 Battery Review

This is my hands-on review of the Enjoybot 12V 100Ah LiFePO4 battery.

Enjoybot reached out to me and asked me if I wanted to try out this battery. I agreed and one arrived at my door a few weeks ago.

I put it through a handful of charge and discharge cycles, tested its capacity, and used it in a solar power system.

After all that, I think it’s a great budget LiFePO4 battery. I tested it mainly as a solar battery, but it’d also work fine for all the other uses of 12V lithium batteries — like camping, RVing, and boating.

The model I tested doesn’t have low-temperature charging protection. But, good news, that feature is available on an upgraded model. It’ll cost you about $100 extra.

A great budget LiFePO4 battery

After a few weeks of testing, I think this battery offers good bang for your buck. It’s a great upgrade from 12V lead acid batteries.

Enjoybot Battery Review

Unboxing & First Impressions

Upon receiving the battery, I pulled it out of its box and did an initial inspection. It was well packaged and arrived in good condition.

Here’s what came in the box:

• Enjoybot 12V 100Ah LiFePO4 Battery
• Bolts with washers
• Plastic terminal caps
• Product manual

The battery has a hard plastic case with a carrying strap that makes it easy to pick up and carry. The case is similar to other cheap LiFePO4 batteries I’ve seen, such as that of my Ampere Time 12V 100Ah LiFePO4 Battery.

If you’re upgrading from lead acid batteries, the first thing you’ll notice is how much lighter lithium batteries are. It makes them much easier to transport. The Enjoybot is listed at just under 23.8 pounds (10.8 kg). For comparison, 100Ah lead acid batteries can weigh over 60 pounds (27.2 kg).

I like the little red and black terminal caps the Enjoybot comes with. They’re just little pieces of plastic, but you can use them to cap the terminals for a little added safety – as well as an extra visual aid to help you quickly identify the positive and negative terminals.

Before using the battery, I checked its resting voltage. I got 13.27 volts. Compared to a generic LiFePO4 voltage curve, this correlates with a roughly 80% state of charge.

Charging

I pulled out my Victron battery charger to charge the Enjoybot up to full capacity at a 0.3C rate (i.e. 30 amps).

Note: You can estimate how long it’ll take your battery charger to charge this battery with our battery charge time calculator.

I also did a complete charge cycle at 0.15C after my capacity test, which I discuss below. At that rate, the bulk charge stage lasted just under 7 hours.

I haven’t had any issues with charging the battery. It’s worked as expected every time.

Capacity Test

After topping off the battery, I connected it to the Victron BMV-712 Battery Monitor and a 2000 watt inverter.

I plugged some incandescent light bulbs into the inverter, enough to discharge it at a roughly 0.2C rate (i.e. 20 amps). This is the C-rate at which lithium iron phosphate batteries are capacity rated.

After about 5 hours, the battery was fully drained and had entered sleep mode. It read about 1 volt with a multimeter.

I checked my Victron app to see the total discharged capacity — 98 amp hours. Exactly as expected.

After disconnecting all loads from the battery (the battery monitor and inverter), the voltage jumped back up to around 10 volts. That was high enough to charge it up again with my battery charger.

I like this self-recovery feature a lot. It saves you from the hassle of waking the battery up from sleep mode.

Installation

I then took the Enjoybot down to my basement to install it in a test solar power system.

The battery worked exactly as expected when connected to a small inverter and 200 watt solar array. I used it to power some lights, DC chargers, and a 12V fridge.

Tutorial: How to Charge LiFePO4 Batteries with Solar Panels

LiFePO4 batteries are my favorite solar batteries. They’re much lighter than comparable lead acid batteries. You can actually use their full capacity, they have a BMS that protects the cells from over discharge, and they have higher charge and discharge rates — not to mention a much longer lifespan.

Key Specs

Note: These specs are for the specific battery I tested. Enjoybot has a whole product lineup of batteries with different voltages and capacities.

• Nominal voltage: 12V
• Rated capacity: 100Ah, 1280Wh
• Price per watt hour (at the time of publishing): $0.30/Wh
• Maximum continuous charge current: 50A
• Maximum continuous discharge current: 100A
• Cycle life: >2000 @ 100% depth of discharge, ≤5000 @ 80% depth of discharge
• Low-temperature charging protection: Available as upgrade
• Waterproof rating: IP65
• Maximum series voltage: 48V
• Weight: 23.8 lbs (10.8 kg)
• Dimensions: 12.95″ x 6.77″ x 8.42″ (329mm x 172mm x 214mm)

What I Like

• It’s a great bang for your buck. This is a good budget LiFePO4 battery. As of this writing, it costs about $0.30 per watt hour. That’s among the lowest rates I’ve seen for this type of battery.
• It has a self-recovery wake up feature. LFP batteries enter sleep mode to protect the cells from overdischarge. Many of them need to be jumped with another 12V battery to be woken up. But the Enjoybot has a self-recovery feature — it wakes itself up once all loads and chargers have been disconnected.
• Low-temperature charging protection is available as an upgrade. For about $100 more, you can upgrade to a model of this battery with low-temp charging protection. If you expect your batteries will be exposed to freezing temperatures, this is a worthwhile upgrade.

What I Don’t Like

• The product manual isn’t very detailed. I’d like to see a chart showing the battery’s state of charge based on open circuit voltage and some info on waking up the battery from sleep mode in case its self-recovery feature were to fail.

Who This Battery Is for

1. You want a good budget LiFePO4 battery. Whatever you’re using it for — solar, RVing, camping — this is an affordable and well-made LiFePO4 for a great price.
2. You want to switch from lead acid to lithium. Lithium batteries are a great drop-in replacement for lead acid batteries with the same nominal voltage. They’re lighter, have more usable capacity, and last a whole lot longer.
3. You need a solar battery. I specifically tested this battery in a solar power system. It works great for that purpose.

The Bottom Line

After a few weeks of testing, I think the Enjoybot 12V 100Ah LiFePO4 Battery is a good, cheap lithium iron phosphate battery. It’s well-suited for use in an RV, boat, campervan, or solar setup.

It charged just fine with my battery charger and in my solar power system. When I discharged it for a capacity test, I measured a total capacity of 98 amp hours. That’s in line with expectations for a 100Ah lithium battery.

It’s got plenty of useful features, too. It can wake itself up from sleep mode. It can be wired in series up to 48 volts. Enjoybot also makes a model with low-temperature charging protection, if you need that feature.

Overall, I think it’s a great battery. If it’s in your price range, it’s definitely worth a close look.
