Good little battery for my solar project. Ah is fairly close to what is stated based upon my observations. I have had a couple that were not close and this one is good. Good price for a good battery of this size and type.

Let me tell you, I’ve gone through my fair share of batteries. From finicky lead-acid behemoths to unreliable NiMH packs, I was starting to think I’d never find a battery that truly delivered. Then I discovered the Timeusb 12V 6Ah LiFePO4 battery, and it’s completely changed the way I power my devices.
First off, the weight difference is astonishing. This LiFePO4 battery is ridiculously light compared to my old lead-acid battery – it’s like carrying a feather instead of a brick! This makes a huge difference, especially when I’m using it for my portable fish finder. No more lugging around a heavy battery all day.
But the weight isn’t even the best part. The performance is absolutely incredible. This battery holds its charge for an unbelievably long time. I’ve used it for multiple fishing trips without needing to recharge, and it still has juice left. It’s also incredibly powerful – my fish finder works better than ever, with a clear and strong signal.
The safety features are a huge plus too. Knowing that this battery is designed to prevent overcharging, short circuits, and other potential hazards gives me real peace of mind. And the fact that it’s non-toxic and environmentally friendly is important to me.
The long lifespan is another major selling point. 3000+ cycles? That’s insane! My old lead-acid batteries were lucky to last a few hundred cycles. This Timeusb battery is going to save me a ton of money in the long run.
And finally, the versatility is fantastic. I can connect multiple batteries in series or parallel to increase the voltage or capacity, which gives me a lot of flexibility for different applications. I’m already planning to use it for other projects, like powering my camping lights and even a small solar panel system.
Honestly, I can’t recommend this Timeusb LiFePO4 battery enough. It’s lightweight, powerful, safe, long-lasting, and versatile. It’s everything I’ve ever wanted in a battery, and it’s completely exceeded my expectations. If you’re looking for a reliable and high-performing battery, look no further!

Used to replace a dead SLA battery in an older UPS. The BMS hypothetically means that the overly high amperage on the charging system shouldn’t nuke the lifepo4 battery or make it explode… and so far it hasn’t. The terminals were a little small relative to the connectors, so I soldered them on instead (my fault for not verifying terminal style first). I’m satisfied by the battery so far. I don’t ever expect to run it dry and it has switched over and charged without issue a couple times already as we have sketchy power service and Spring winds consistently cause short interruptions. With luck, it will last a good 2-3 years.

First & most importantly, this appears to me to be a good LFP (lithium ferophosphate) battery. I bought my first inexpensive 4-20AH LFP Charger and used it in my testing. After charging, I let it rest and 36 hours later the reported voltage has settled down to a ~13.5-13.6 range which, according the SoC (State of Charge) Table, translates to 100% charge. On the shelf that charge level degrades VERY slowly.
I have worked with SLA (Sealed Lead Acid) batteries of this form-factor for decades. This LFP battery feels like the case is full of air, it is so very light. I just checked its weight against one of my 9AH SLA Spares: LFP= 29oz & SLA= 87oz. So, about one third of the weight of the SLA. Wow.
I had *hoped* to be able to drop this into one of my single-SLA-battery UPSes. It didn’t work out that way … YET.
Over the course of few years I have read posts from various people stating that LiFePO4 batteries of proper form-factor could be used as simple drop-in replacements for the SLA batteries in UPSes. After I got this battery I did some research on the subject.
Only 2 flavors of my readily-available UPSes (4 units, total) are of a single “12v” SLA 2½”x4″x6″ F2-terminal battery type. I checked both types and their circuitry runs with the standby/float voltage at ~13.8v. From what I have read that is too high for long-term usage without degrading my LFP battery. The “targets” appear to be Float Voltage no more than 13.6 and Charging Voltage no more than ~14.7.
Like I said at the top, this appears to me to be a good LFP battery. O’course my only prior LFP-specific experience has been several years with 18650 batteries. Once I find a “compatible” regular UPS I will be testing this TimeUSB LFP battery as a UPS replacement.
=========
[EDIT]
HOORAY! I located a compatible regular UPS in my lineup. Two, actually. One is my “ONT Paired” CyberPower CST625G that I reconfigured for use with external batteries (allows for lonnnng term power for my FiOS ONT during power outages … it matches my Router UPS setup, btw). The second is a CP ST625U paired with my north (bedroom) alarm system controller. The standby/float voltages on both fluctuate between 13.58 and 13.60. Perfect!
I do not want to change the ONT UPS setup but, with some furniture moving and reconfiguring of the cabling & switching I have installed my LFP battery in the ST625U. Since the UPS battery form-factor is ½” narrower, I simply banded the unseated access panel over the protruding LFP battery. Not the first time I have run one of these that way. 🙂
Now, for what IMO is the more important part of this Edit. The individual unit-plugs-directly-into-an-outlet battery chargers (I have 4) that I have used for a couple of decades operate in a manner with which I am well-versed. Attach the 2 alligator clips to the F2s on a removed/new UPS 9AH SLA battery and then plug-in the charger unit. After a moment the indicator light glows RED. The voltage reported by my piggybacked Volt/Ohm Meter slowly increases to 14.36V and then stops charging, turning the indicator light from RED to GREEN. The battery V starts to drop and with the hour, for a new battery, will settle at 13.15±.05.
I have always ASSUMED that the recharge circuit in UPSes operate just_like_that. Turns out, for some of them, at least, I was wrong.
I tested the Float voltages in several different brands & types of UPSes because Float was (much) more easily tested. When I had my 2 “compatible” candidates (Floats of no more than 13.6) I set about determining that the Charging Phase high voltage was no more than 14.7v.
I found that neither of the UPSes sports a separate Charging Phase. The Float voltage IS the Charging Phase. The batteries are simply “trickled-up” to full charge.
Something to keep in mind for those that may be considering combining LFPs with regular UPSes.
FWIW, I am tentatively adding to my online Tickler File a Drain-to-50%-and-LFPRecharge at least once a year just to keep this LFP healthy(ier). Perhaps More? Time for more research on the subject.
I apologize for the prolixity, but I thought that it might be important to some.
Enjoy! 😉

[EDIT] … last time, I promise. 🙂
The way that my *LFP* Charger Operates:
BTW, I always piggyback the Volt/Ohm Meter so I can see the voltage changes.
Attach the Charger alligator clips to the battery F2s, plug the Charger in, Charging Mode starts and the RED indicator light comes on. It stays ON until the voltage reaches ~14.7. The Charger cycles ON(RED) & OFF(GREEN) periodically. At first the ON mode is active for much longer than the OFF. As the process continues, that trend reverses as the OFF mode voltage increasingly remains high longer before dropping off and triggering another cycle. I like to wait until the unit has gotten to where it stays OFF for at least a full minute before unplugging the charger & disconnecting the battery.
As the battery cools and the voltage settles, it will eventually end up at ~13.50-13.60, indicating a 100% charge.
