SEFEPODER 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

Much lighter than my old battery that was Li-ion. This LiFePO4 battery is a significant improvement. I put 2 into my Metro Mobility M1 motorized wheelchair, and it works well, the capacity is larger than OEM, and took longer to charge? About 8 hrs, but looks like there is a corresponding increase in distance. Good value and option. I had to use small screws for terminal connections. It doesn’t have a screw hole like the OEM

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 & Capacity After 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 & Design The 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 & Instructions The 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 Charge The 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 Thoughts Extremely 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!

so far its holding life. the only down fall is that it take FOREVER to charge up. overall its legit. Going into my 2nd year for ice fishing.

If you have an old Black and Decker 36v Battery-powered mower, these batteries are a perfect swap. I replaced the three batteries in my pack on my SPCM1936 (self-propelled version). After removing the lid on the removable battery pack, my old SLA batteries had bulges and corrosion. These fit in the box without any modifications. Plug & Play. Definitely could feel the lightness of the new batteries compared to the lead acid ones. The original brick charger works perfectly to recharge these, as their max charging amperage exceeds what the charger outputs.

I don’t write reviews very often but this is a great product works great and has a long life I Have had others that cost more and are not nearly as good so thumbs up on it

Battery was used in a solar water fountain. By the time I was able to trouble shoot the problem, I was a few days past the one year warranty. I think they design in what is called "functional obsolescence". In other words, it becomes obsolete after warranty expires. Obsolete functionally because it is unable to hold a charge. So you need to replace battery. They keep you buying batteries every year instead of making them to last. There is a lot of electronics besides just Lithium cells inside. Great battery if only it didn't fail a couple days after warranty

Worked Great and long lasting

Highly recommend the battery is half the weight of the lead battery makes the cart go faster and battery life lasts longer than the lead batteries

Buena bateria,pequeña pero con la capacidad que describe.Ideal para Fishfinder.
