12V 20Ah Lithium LiFePO4 Deep Cycle Battery 2 Pack with 40A BMS | 4000+ Cycles Rechargeable Battery for Electric Scooter, Ride On Toy, Lighting, Power Wheels, Fish Finder and More

I have been testing this battery and the results have been exceptional. It is an incredible improvement compared to lead batteries. I was surprised how light it is for the power it offers, which makes it much easier to install it in small spaces. I put it in my girl's sheep and it adapted perfectly. If you are looking for a reliable battery, this is a safe investment. Very satisfied with the purchase!

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!

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.

I used these to replace the lead-acid batteries in my Ariens AMP24 snowblower. The snowblower originally had 12ah batteries and then had one upgrade to 15ah batteries before I switched to these lithium 20ah batteries. Runtime is significantly longer than before. The original charger will charge these but never reaches a "full" state, but will charge it enough to get a full reading on the snowblower and thus be usable for my driveway in Wisconsin. I did purchase an extra 48v lifepo4 charger as a trickle charger for keeping these batteries topped off all year round. Also, these batteries are much lighter than the lead-acid, so it's easier to wield the snowblower. And if you're wondering why I don't use a gas snowblower, it's because I have asthma and can't handle the gas fumes.

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.

Ok

I swapped out the typical lead acid AGM 15 AH batteries with three of these in a stock Razor MX650 dirt bike. The physical size and the wiring terminals are identical to the originals so replacement is a breeze. The extra range, charging speed and lighter weight makes these a decent upgrade. The batteries can handle the full load of the bike motor without cutting out. Make sure to pair these with a proper LiFePO4 charger. The typical lead acid batteries only lasted a year with an occasional 100 lb rider and good maintenance. I will update this review after more time. I expect these will last longer.

The power and capacity is amazing and rapid recharge too. A bonus is half the weight and double the output. One warning what the charge level as it drops.it goes from low to zero fast , but you get full power till then,
