12V 20Ah Lithium LiFePO4 Deep Cycle Battery, 3000+ Cycle Rechargeable Lithium Iron Phosphate Battery for Solar, Fish Finder, Marine, Outdoor Camping, Off-Grid Applications with 20A BMS

I’m a ‘over the top amateur radio operator’ who is very involved in our ‘When All Else Fails’ charter of organized partnerships backing-up emergence communications of city, county, state agencies in organizations like RACES (Radio Amateur Civil Emergency Service). The ‘When All Else Fails’ comes from ham radio enthusiasts pride themselves on maintaining there stations totally independent of local power grid, internet, … and at our own expense have backup generators, spare car batteries, solar panel or two,,, mobile radios in our cars and HTs with many spare batteries. Lion batteries like this one are the new thing! Much more capacity/ operation time in a much smaller AND LIGHTER! size. While initially a bit pricey, competition and more efficient manufacturing has kicked in and we are now seeing grear reductions in price… AND increased capacity. After a lot of reading/ comparison this is the battery I chose as best capacity/ price/ sturdy case!

yes, they directly replaced the batteries from my dads electric chair. The old ones was sealed led acid. these have more life and 1 amp hr more than the old led acid ones. so more juice!!!!, much lighter.. Understand these have a BMS (Battery Management System) built into the battery... So, i'm able to use the normal battery charger for the electric scooter.... I don't leave any battery always plugged in and charging... Especially lithium ...(let it charge and then unplug.)

I bought the 20ah and a 30ah. I'm using them to run my Garmin Livescope system which I'm viewing on a Garmin 1022. Total draw is estimated at 3.6 amps. I wanted the 30ah for my primary and the 20 for a backup in case the 30 ran down before I was finished. So here's the rub. So far, I've only had one trip (the first trip out) that the 30ah worked right. Every trip ever since that one, it has dropped below 12v within 30 minutes of using it and I've had to switch to the 20ah (which has worked flawlessly). I really wish that I had waited to buy these batteries until the weather would allow me to go more. If I had, I would've returned the 30ah battery after the 2nd trip. I just went fishing again yesterday. Both batteries were 100% charged when I left for the lake. As soon as I hooked up the 30ah to my electronics, it was only reading 12.1 volts. Within 15 minutes, my alarm was going off on the graph saying low voltage. It was already down to 11.8 volts. 5 minutes later the graph was preparing to shut down and I had to swap out for the 20ah battery. Fortunately, the 20ah battery ran my fish finder for the rest of the day with no issues, maintaining 12.5 volts the whole time. I bought this in January, so it's too late to return it now, so I guess I'll have to trash it and buy another one. I will not be buying this brand again. At least it wasn't as expensive as others I've seen, but I still feel like I was ripped off. Had it worked as well as the 20ah has (so far), I would've felt like I got a great deal. Buyer beware. Update 6/7/2024 Now I've used this battery several times and I've tried everything to try and make it work right. Someone posted that I needed to drain it all the way down and then recharge it. I hooked up a small 12v fishing light to it, but it cut the power off to the light as soon as it got into the high 11v range. I can charge it up to the point of reaching around 12.5v, but that seems to be the limit. As soon as you remove the charger, the voltage starts to drop on its own. I took it fishing one last time last weekend and this time it only ran the fish finder about 5 minutes before my low voltage alarm started going off on the fish finder. Within 10 minutes, the fish finder turned off and I had to switch to the 20ah battery....which, to it's credit, has worked flawlessly up to this point. Maybe I just got a bad battery. I don't know. Again, I really wish that I'd have used it sooner so could have returned it. At least that way I'd know if this is the norm from this company and the 20ah is the exception, or vice-versa.

These batteries fit perfect in the original battery case for my mobility scooter. It was a simple unscrew a couple screws switch it out and screw back in. They are a lot lighter then the acid batteries that I replaced. I charge it overnight and it was ready to go. There is an increase in speed and I was able to travel longer on the one charge

Provides a good power source to keep my peripherals charged while out on my adventures. The lightweight of these LiFePO4 type batteries is much better than comparable lead acid batteries too. I already have enough weight from all my gear so everything counts. Also, this brand costs less so it doesn't lessen the weight of my wallet too much.
