12V 50Ah LiFePO4 Battery Rechargeable Lithium Batteries, 3000+ Cycles Lithium Iron Phosphate Battery, Perfect for RV, Solar System, Trolling Motor, Camping, Marine

I’m using this 12V 20Ah LiFePO4 battery to run electronics on my fishing kayak. Mainly a Garmin Striker 4 fish finder and TD6E thruster. It holds a charge well for long fishing days, and I haven’t had any issues with power drop or BMS overheating. It’s lightweight, easy to carry, and seems well-built. I like that it has BMS protection, so I don’t have to worry about overcharging or draining it too low, or overheating. It’s a little more expensive than the lead-acid battery it replaced, but the much longer life and better performance are worth it. Bluetooth connectivity would be a nice to have to see capacity from your phone, but has not been an issue for me so far.

Super light and easy to install. A big improvement over my old lead-acid battery. Holds a charge well and lasts a long time. Feels safer and more reliable.

Thanks exactly what needed for my battery bank addiction.

The media could not be loaded. Powers my small UPS units just fine. I love how light, yet more energy dense, than the lead acid batteries. My previous external UPS backup lead acid battery weighed ~22lb with a 10Ah 12V capacity. This new LiFePO4 backup battery is twice the capacity at less than 1/4 the weight. Price-wise, this LiFePO4 battery is slightly cheaper than my previous lead acid battery.The bolt-on terminals are comparably small and should have included washers to help secure any contact connectors. Terminal connection was OK, but I had to supply my own washers to have a more secure connection. The modern built-in BMS made installing this battery easy, in that no additional electronics or modifications were needed to connect to a legacy UPS unit. Hopefully, the BMS will keep the battery lasting a long time.So far the battery is worth its value.

I got this battery for powering my portable projector and charging all our devices when we're camping. It's super compact and light, making it easy to carry. It's powered our setup for whole weekends without issue.The built-in protection is great too, it shut off automatically when I accidentally drained it, and recharged fine. So far, it's been a reliable powerhouse for my outdoor needs. Great buy!

I can't say anything about long term longevity yet but the capacity rating was accurate. It seems to shut off somewhere around 9.5 volts. That seems a little bit low. It should be 10v. Also the low voltage cutoff seem to re-enable the battery after a few minute then cut off again. I haven't experienced this with any other LiFePO4 batteries I have tested. Usually you must charge the battery first. I won't give this battery a perfect rating but it seems to be acceptable quality. I didn't attempt to test the other protections.

I installed this battery in my small boat to power my electronics. It’s compact enough to go unnoticed but powerful enough to run my plotter, lights, radio, and keep my phone charged all weekend. I haven’t needed to charge it during a weekend yet. I keep it in a small waterproof box to protect it from the elements. I accidentally drained it completely once, and the BMS shut it down to prevent damage, which I appreciate. This is a reliable LiFePO4 battery that performs well for a reasonable price.

This Lithium Iron Phosphate battery is ideal for portable power needs, power during outages, or UPS needs. The battery will supply up to 100A continuous which paired with a suitable inverter should provide up to 1000+ Watts. Direct connections should power most 12V needs. I'm using this and an inverter to provide backup power for my fiber modem and wireless router so they stay working during power outages.Because this is a LiFePO4 battery, it really should be charged with a compatible charging device that is designed for LiFePO4. This allows for the best charging profile and cutoff voltage.The two battery terminals are color coded with black for the negative and red for the positive. Many backup batteries just have the plus and minus signs molded into the case so the color coding helps prevent reversed polarity. Very good battery for UPS usage.
