12V 20Ah Lithium LiFePO4 Deep Cycle Battery, 4000 Cycles Rechargeable Battery for Electric Scooter, Ride On Toy, Lighting, Power Wheel, Fish Finder and More with Built-in 40A BMS

I have been running these in my home made battery box for a few months now and have been thoroughly impressed with their performance. You can tell from the clean construction that these were high-quality batteries.Performance & CapacityAfter running a capacity test at home, I confirmed that these batteries deliver their full-rated capacity. They performed exactly as expected, maintaining a stable voltage throughout the discharge cycle.Build Quality & DesignThe construction of these batteries is top-notch—solid and durable. One of the standout features is their compact size, which is notably smaller compared to similar products in the same category. I find this to be a huge advantage in my limited space application.Additionally, these batteries are lightweight, which helped reduce the overall weight of my homemade battery box. The weight savings alone made these an excellent alternative to my old sealed-lead-acid (SLA) batteries, which were significantly heavier and bulkier with far less capacity. I was able to increase my battery life 5-fold with this switch.Ease of Use & InstructionsThe included instructions were basic but relatively easy to understand. While they provided the necessary information for general use, those unfamiliar with LiFePO4 batteries may need to do a little extra research to know what the specification tables mean (such as what the charge [C] rating of your charger should be). However, for anyone with experience using these types of batteries, setup should be straightforward.Shipping & Initial ChargeThe batteries arrived quickly and were delivered in perfect condition. They came with an approximate 30% State of Charge (SOC). Charging them up to full was quick and hassle-free.Final ThoughtsExtremely satisfied with my purchase. Overall, these SEFEPODER LiFePO4 batteries offer great quality, reliable performance, and an excellent weight-to-capacity ratio. Given their compact design, lightweight construction, and full-capacity performance, I wouldn’t hesitate to buy them again. But with 4000+ rated cycles, why would I? LOL⭐ Highly recommended for anyone looking for reliable and efficient lithium batteries!

Tested slightly above rated capacity at a .2c disharge rate. Fits in the Garmin Livescope shuttle. Appears to be a good battery at a fraction of the price of name brands. Time will tell if battery lifespan is good. Very satisfied with this battery purchase so far. Recommended.

After making sure the battery was fully charged I used it to run myNilight Side Shooter LED Light Bar 2PCS 4.3 Inch Triple Row Spot Flood Combo Lights with Wiring Harness Kit for Off Road Fog Driving Work Lighting on Truck SUV ATV UTVOn my kayak and left them on. The battery lasted around 9 or 10 hours before the lights shut off. That is plenty for night fishing! If the battery itself last then I'll buy a couple more.

Purchased these to replace the lead acid batteries that had been installed in a Pride Elite mobility scooter. There were zero problems with the install and the batteries work great. It should be noted that since the charge profile and discharge behavior of these batteries is quite different than that of the AGM batteries supplied with the scooter. This means that the battery charge indicator on the scooter will not accurately tell you what your charge level is in the batteries. With these batteries, the display will probably indicate a full charge right up to the point that the scooter quits. So if you buy these just keep note of your usage or install a charge indicator designed for Lithium Iron Phosphate batteries.. Also, you will need to get a charger designed to provide the higher voltage needed to charge Li Ion batteries. This was all pretty easy for us to accommodate and the reduced weight and cruise-ship compatibility of the batteries made the swap a good choice.

Great 20 amp hr battery. Runs xfinity wifi box for hours!!! Solid. Chargers quick

A lot of power for the size and weight.

Bought last summer (August) for winter portable fish finder.40 minutes into first use (January), battery went dead.Zero voltage at terminals. Won't take a charge.Can't return due to time, even though it was still in box until a week before use,.Update: Did some more research. Flashed battery and got it working again. My understanding battery should not shut off until 10V. It shut off at 12.3 V. Will charge again and try once more. Will post results.

Capacity seems to be exactly what is promised. I have purchased about 8 of these so far. One didn’t function and was replaced without hassle. Been using them about a month and everything seems to be working as expected. Seems like a decent battery and good value.
