12V 100Ah LiFePO4 Battery, Up to 15000 Deep Cycles Group 31 Lithium Battery, Built-in 100A BMS, Perfect for RV, Solar, Camping, Marine, Trolling Motor and Off-Grid Applications

GOLDENMATE 12V 100Ah LiFePO4 Lithium Battery (2-Pack, via Amazon)My initial order of 2 of these batteries arrived with only one. Fortunately, after trading emails with Amazon Customer Service and through it the seller, the shipping SNAFU was quickly addressed and the 2nd arrived before my electrician did. So no harm done! The error was addressed promptly and efficiently. Every business has issues from time-to-time, it is to be expected. The exceptional business acknowledges them, addresses these promptly, reviews its processing for improvement, and keeps their customers for life - as you have done. The batteries themselves are perfect: half the weight of my previous LA batteries, quick connection to alternator and easily accepted by the Go Power GP-PWM-30-SO solar controller. Thank you so much for the great value and terrific service. I would definitely buy from this seller again. ATBster, aboard a Micro Minnie 2306BHS.

Took out the two Group 24 RV batteries in my RV and installed this. It's lighter, longer-lived, and has more capacity considering that it can be discharged much deeper than a lead-acid battery before the voltage drops too low. With a 255-watt solar panel on the roof and an MPPT charge controller in lithium battery mode, I never need to run the generator, which is a good thing since lithium batteries are not designed for the cranking amps to start a gasoline engine. And if you don't use a solar charge controller to keep your lithium battery charged you must do something about your rig's converter and alternator which don't get along well with lithium batteries. On shore power the converter will cut out before the battery is fully charged if it's not lithium-aware, and on the road the battery may pull too much power from the engine's alternator if it's very low on charge.

I have a 25 year old APC SmartUPS 900, that is protecting my Internet gateway since 25 years. Back then, 56k leased line, now Gigabit. This UPS originally used 4x 6V lead-acid batteries with trickle-charge. Because the UPS does not have an 'intelligent' charge algorithm that charges a Pb battery in two or three phases, it typically cooks-off a set of batteries in 3 years. I use two GOLDENMATE in series, reduced the protective fuse, since it has about 30% the max discharge current when compared to the Pb batteries. But this is fine since I only run a cable modem, switch and small ARM based firewall, three access points and a SoC based controller, drawing less than 100 Watts. The system draws more when booting of course, perhaps twice as much. I have it now running and tested in discharge and charge modes, and appears to work well with the UPS and the GOLDENMATE LiFePO4s with the UPS' its trickle-charge charger, the built-in BMS taking control - looks like the datasheet is trustworthy. Batteries stay cool.

These batteries are well made and very fast at charging. They are also light and easy to use.

works great for starting a 10hp honda outboard

So ill do a review because I ran this battery to zero (you can do that with lithium) I didnt see any reviews with this information in it. if you run it all the way to zero the battery will report zero volts. It is not dead. You simply need to jump it and add a little 12volts to it for 3 seconds. That will give the BMS time to start up and it will report 10 volts. Then it will take a charge.Good battery Nice capacity and a good weight. I love mine. Ive had it a year now. Just killed it and learned that you just have to give it some juice to get it to start. It isnt dead.Enjoy!

I bought this to use as a backup power for aquarium pump in case of an outage.I have used sealed lead acid batteries, in the past, but they started losing charge in less than 3 years. They are also heavy.The LiFePo4 batteries, on the other hand, keep charging for up to 10 years and are lighter than a comparable SLA battery.While it's too early to comment on its longevity, I can definitely say this battery is smaller and lighter than the SLA battery.I should also point out that this battery is rated at 20ah, while the SLA is 18ah.Tried it on my Vortech MP10 and it works fine.

Im using it for landscape lights about 20 of them I connected the battery to a 150 watt panel to power my landscape lights for 5 hours a night and after 10 months no issues. works as intended.
