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

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!

Using with a small, 200w inverter that costs $30, a solar charge controller ($10), and a 240w pv panel ($150). It powers (4) DC interior lights that provide more than enough light for the interior of an 8x10 shed. It also powers a Wyze surveillance camera and a Ryobi battery charger. I returned a $300 power bank that couldn’t handle the pv input wattage or charge below freezing temps. Using this with the inverter that has 4 USB ports (2 an and 2 c) along with 2 ac outlets gives me more than I need with room to grow, without the limitations. Also takes up way less room as it fits on a 2x4 shelf within the interior frame of the shed wall. In terms of battery life I’ve checked the solar charge controller multiple times at days end in the winter, on cloudy days, and it’s never been less than 75%. This set up provides much better performance and reliability compared to the power bank.

lightweight, good price, long lasting

This review comes after many months of use in my mobility scooter. ZERO complaints. Holds a charge well and charges in a timely manner. Would purchase again. 👍

Connecterd the 2 for 12 volt use (ie: Red to red). Arrived charged, but put it on trickle anyway to top off. Checked before use, 13.45 volts. Used for my electric 30 lb thrust boat motor. Rode around the bay picking up my lobster traps (6) with both wind and some current from incoming tide. Several trips to shore and back out for traps. Checked voltage after returning home. Registered 13.23 , so only ".23" used ! I was expecting "much more drain of batteries. Could likely use one, but love the extra just in case day runs long. These offer 5 amps each. I want to run a 10 amp wench to pull wheel chair up into home on ramp, and to lower elderly down the 7' ramp. I'm ordering another set now. Very pleased. Lithium LiFePO is the cadilac of batteries, comes completely sealed so no caps and spills, and these are very light weight as all LiFePo. Note: This type battery requires LifePo charger. These arer cheap and small. I purchased a 4 amp charger.

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.

This worked perfectly as a drop in replacement for our kids’ off brand toy Gator. They can drive it around the yard for hours now. We are into our second season using it, and it seems to be holding up well.

I installed these batteries on my wife’s scooter a month or so ago. The third time she used it which was yesterday one of the batteries just died. I charged it the night before it was working fine. She was rolling across a hotel lobby and it just quit. when I diagnosed it one of the batteries has 0 V across the terminals. The other batteries is fine. I’m assuming the battery management system inside the battery failed. And of course it is out of warranty now.
