The best way to measure power in and out is to use watt hours not amp hours. When your charging the voltage is higher to cause the flow back to the battery when you discharge the voltage sags and you pull more amps to achieve the same wattage. I have 28 of these batteries in an off grid setup and if you don't abuse them they work just fine. Thanks for the follow up to your previous video as well I'm glad to see others having success with these batteries
Great review on the cheap lithium batteries mate. The way of the future for sure. 50 amps discharge is low but if you just want a cheap light weight lithium battery to power the camper trailer fridge/lights etc go for it. Even if it lasts 5 years I would rather use the 80% power instead of 50% agm.
Great to see local content keep it up. The first discharge you did the shunt said you were discharging 550 watts but the two after that said 490-495 watts, could the less watts on discharge get more out of battery? I saw these were for sale at Aldi and nearly pulled the trigger but noted the max discharge was only 50 amps which is fine for DC loads while camping but if you start using inverter for big loads like induction cooking the bms will turn off the battery. Still if using for dc then probably difficult to over load bms. What I like about this battery is the price. Affordability means more people can get into the product.
Thanks mate appreciate it. Yes it definitely is possible why I got better results. Like you said 50A is fine for DC loads, but when you want to push it. It is not enough especially when trying to use it with higher loads. For what most people use their batteries for and how often, they are at great value and do the job fine.
@@ewkaus I bought mine from DickSmith for $329 I paired it with a 600w pure sine wave inverter and it works really well, I've used it on a rice cooker, Xbox and gaming computer
That’s really good for a cheap battery . Even pulling over 40amps continuous is impressive. For the cost of this battery you are still winning. Great job well done 👍🍻
10v will be the limit when drawing current. Your inverter will also cut out before.. these batteries are good value either way. I have a 300ah voltx battery in the back of my car. It would be even cheaper to buy these batteries, open then up and build a bigger battery with a new BMS for solar applications rather than buying individual or packs of cells.. I might try a capacity test as well as I have a Bluetooth shunt but only a DC/DC charger in my car. you'll need to get the right size charger as well. 15a is not that good. Try 50 to 100a...
These batteries generally will have used 120aH cells. This means you will get the full 100aH rating but the cells are already approx 80% capacity at this point. Few reasons for this but essentially its expensive to recycle lithium batteries, so they are just recycled. They will still work fine, but do not expect 3000+ cycles. In other words, you do get what you pay for.
Watch the tear down video of these, they aren't prismatic cells like the voltx, cheeky marketing I think with the names being so similar. Voltax battery's are little individual cells. I don't think they were 18650s but something similar
@BadIdea1123 i had two of the grey voltx batteries i planned to run in parallel due to their 50a discharge only, being parallel i had hoped they would do 100a discharge for a bigger inverter but voltx stated at the time they were not okay to parallel !!! Anyway i capacity tested them both and only got 98 from one, 97.2ah from the other and that was on the day of purchase! Test done with a zke tech ebc A20 which i have proven accurate with a victron bmv712. Theres a few teardown videos of the voltx batteries and they are poor build quality as well as being used cells
Thank u for ur efforts,I have just purchased the newer voltx from ALDI with a3 year warranty and am trying to decide if I actually open it and make the leap in the lithium world for my caravan
Thanks Terry. i personally find lithium is much better, greater depth of discharge and also so much lighter. Just need to make sure you have the gear to charge it and be aware of what you intend to use the lithium battery for.
On the second cycle the inverter didn’t shut down till just above 11v The first cycle the inverter cut out at just over 12 v This is not the battery’s fault Just over 100 ah you see the voltage fall off quickly as expected The battery was preforming slightly better than rated Recharge time will vary with temperature and voltage applied from chargers
Think others have said, these cheaper batteries are likely using recycled cells. Fine by me given the price point. I just got some Eco-worthy 100Ah batteries (which have 100A BMS) off eBay and expect very similar performance. One thing to note is that standard battery test is at 0.2C, where here you are at 40A which will be 0.4C on this battery. Makes it even more impressive you're getting the full 100Ah after a year of use.
Have have you been going with the Eco-worthy out of interest. I've seen their gear online and it doesn't look like complete junk with fake specs from what I can tell.
Thanks mate. Installed in a canopy but currently sitting in an outside box powering a CCTV camera. I wouldn’t put this battery under the bonnet. Not sure it could handle the heat.
Good video. One question. Have you tested the battery BMS. ? Low and High temp cut out. This to me is what people really need to know is the safety of these batteries as one does not want to lose there caravan due to fire caused via battery.
Hi Gary thank you. Haven’t worked out a way to test this and it is definitely something I would like to do in the future. I personally think there are risks with all batteries and as long the battery is used within specs and installed correctly the risk is minimized.
You should probably have other safety’s in ur circuits such as fuses &/or C/B’s anyhow, the BMS is more a protection system for ur battery & cells of course. I think this battery has come up good, so far, but I am not sure if this one does actually have a low temp cut off. 50A capable BMS is not bad for this price point, I wonder if they can parallel or series ok, & if so, how many S&P series? Cheers
LFP batteries are inherently safe - fires will "normally" only be caused by bad DC electrical system. (if such a thing can be called normal)- don't confuse with LCo or LNMC Li-Ion batteries, these are different - ie LiFePO4... Also, if travelling in cold climates, it may be better to keep the batteries from freezing with a heated and insulated box, than to rely on BMS low temp cutout - (thermocouple and reader are cheap insurance) sure not always convenient.
What's your thoughts on fully charging a lithium battery? I have watched videos where they suggest leave it at 50% as it is better for lithium and it will last longer, how are you supposed to do that when it lives in a caravan and you want it charged for the next time you go to use it.
Hi Geoff I’m not sure about that. I personally use a 7 Stage charger and let the charger work it out what to do. I’m trusting the charger is smart enough to work out what do to ensure the battery is maintained correctly.
That was my question as well. We would really need to see the usage profile to make a reasonable assessment of how good it is. Having said that, this is the only long term test of an LIFEPO4 battery I have been able to find. I see lots of words about how great they are, but no real world user tests.
Have 2 of these in series, ran our off grid setup for 2.5 years so far. Great bang for buck.

Amps gives a real visual for the layman of how much can be used, like a fuel tank, Watts is more charts and figures formulars
The voltage cut-out was lower each time that's why capacity was more each time.
Good to see your follow up review on this battery and it is still performing well. Seems like it has been replaced by VoltX brand.
Thank you. Yes they did a name change for some reason.
Great review on the cheap lithium batteries mate.

Thanks Brent. Appreciate it. Couldn’t agree with you more.
Mines been going fine, 135 ah. Can only see potentially if running tools on big inverter may need more grunt

50amps is still around the 600watts, in a campsite setting 600watts can run lots of stuff
@@tucker2074 that’s right. Really depends on your setup and what you want to power.

Awesome Ray. That is great to hear!
Actually what should I set my float voltage at for these batteries
@@terryadamz870 The Victron charger by default for Lithium profile is set 13.2V.
On the second cycle the inverter didn’t shut down till just above 11v
The first cycle the inverter cut out at just over 12 v
This is not the battery’s fault
Just over 100 ah you see the voltage fall off quickly as expected
The battery was preforming slightly better than rated
Recharge time will vary with temperature and voltage applied from chargers

Nice video mate. Where did you install the voltx battery?
Do you think it would be ok installed in under the bonnet?
Thanks mate. Installed in a canopy but currently sitting in an outside box powering a CCTV camera. I wouldn’t put this battery under the bonnet. Not sure it could handle the heat.
Would love to know how your Kasan 100a/hr is holding up.
Thanks for this vid mate.
Hi Seth. Thanks for that. The Kasan is still going strong.
Nice work
Thanks Craig. Much appreciated.
Are these same as volt X?

Have or could you do a test on iTechworld 200amp lithium battery
Will have look at them and see what I can do.

@@ewkaus thanks mate, just seems crazy to have a battery and only want it charged at 50%
Without the knowing how many cycle's this battery has had what's the point ? It could only use 200 watts a day.
That was my question as well. We would really need to see the usage profile to make a reasonable assessment of how good it is. Having said that, this is the only long term test of an LIFEPO4 battery I have been able to find. I see lots of words about how great they are, but no real world user tests.
Seams slow charging. Is that because only charging on 15amps?
Yes and also due to charging profiles of battery charger.
Why are drawing 0.2c
Nothing to be impressed battery volts is going LOWER 12volts should be cutout
