iTechWorld 120X Pro Bluetooth Lithium Battery Review - ANY GOOD?

[@robpinter5431]

Thank you , your work in testing is appreciated, I replaced 3 100 Ah AGM's in my caravan with one iTech 120Ah about 2 years ago and still happy with it. Well worth the extra money for a reliable and well made battery.

[@TheMusingGreg]

Thanks! It's encouraging to hear your battery's lasted that long, that bodes well for those like me who don't have that experience! Thanks for sharing, and glad you enjoyed the review! Please share it with others who might not yet have decided, if you can spare a moment! Thanks!

As always a very thorough in-depth product review. 12 months ago I purchased a complete kit from itechworld which included 3 x 120ah Pro Lithium batteries, 12VDC 40amp battery charger, 40amp DC-DC charger with solar panel input and a battery charge monitor. Very very happy with the performance and absolutely no issues. I did upgrade the battery monitor from the older round style to the one you have. My very small van (12’) has a shower & toilet, air conditioner, fridge, microwave, induction cook top, TV and range hood and the setup has no problems running for 3-5 days off grid. They’re a pretty helpful lot at itechworld too which means a lot. If you have an email I’ll send you a photo of the power setup. Cheers.

Thanks, always great to have your feedback! Yeah in general I've been pretty happy with most itechworld stuff, I feel it strikes a good balance between budget and top of the range. I was a little disappointed with how long it's taken to get my questions answered, and even now I've still got my older batteries the same ones as you'd have because I'm waiting to see if I have to send these new ones back or not. It's been over two months I've been trying to get this all settled, which is unusual because generally their support as you said is prompt. Would love to see a snap, [e-mail]. Cheers!

Ripper vid. I've been looking at batteries for my camping set-up, but wasn't sure if it was worth paying extra for an iTech over a Kings, but you hit all the points I had questions about and have sold me on it. Fantastic vid and thanks for sharing.

[@TheMusingGreg]

Brilliant, that 's exactly why I do these videos! Glad it helped settle the decision for you. The current $799 is the cheapest I've ever seen these batteries, so with my coupon code you're going to get them for about $760 which is stupid cheap for what they are! And I think they're doing free shipping too! Please share the video on your socials!

I really appreciate the time and effort you put into your reviews.? With your honest opinions I just used your discount code to purchase a go further battery box. I’m considering getting an inverter as well would you recommend a 3000w or just stick to a 2000w as I just want to run a fridge and freezer when we have long black outs this summer. Apart from that the main use will be running a fridge and lights when camping. Cheers thanks again

[@TheMusingGreg]

Hey Matt great to hear you found it useful, and thanks so much for your support, I really appreciate it! As to the inverter: the main question is how much power you're wanting to draw at any one time. In relation to black-outs: 1) Is the fridge and freezer you're wanting to run a domestic 240V unit, or is it a camping version with a 12V input? In either case, how much current does it draw while running? 2) Would you ONLY be running the fridge and freezer off the inverter, or would anything else be running at the same time? If so what else would you be using and how much current does it draw? In relation to camping: 3) Is it a different fridge you'd be using with the lights? If so what current does it draw? I assume the lights won't draw much unless they're halogen. My gut feel is that the 2000W unit will do the job, but let me know the answers to the above and I'll give you my recommendation. Cheers, Greg

Fantastic and thorough video 👌🏻

[@TheMusingGreg]

Thanks for the feedback! 👍

When you do a discharge test with the smart shunt set the retain state of charge to on. Then when battery disconnects you keep your information.

[@TheMusingGreg]

Thanks for the tip, I'll definitely it that in future! I didn't know it had that feature, I bought it for this test so hadn't played much with it. Cheers!

They do promote the ability to use existing AGM chargers, but there are plenty of caravan AC chargers that won't work well. Before deciding if your old van charger will work, check to see if it can operate in power supply mode and give a constant voltage without trying to read voltage from the battery to determine charge rate. That might be a simple way to get a better result, although investing in a proper lithium charger is 100% the way to go - most AGM/Lead chargers won't deliver 30+ amps, and you need plenty of charge current if you have high capacity lithium batteries.

[@TheMusingGreg]

Good points. I doubt many older power supplies would have the option for power supply mode, and in any case it would give a constant voltage whereas iTechWorld recommends dropping down to 13.5 volts for float. Lithium charger is certainly the best option and as you say that will probably give you high current as well, but the takeaway for me is the 13.5v minimum is key if you're reusing an existing charger. Thanks for your input!

[@einfelder8262]

@@TheMusingGreg Dropping down to 13.5 for float should be done by the BMS, even if there is 14.x at the terminals. I have noticed that my same brand battery/charger in my Patrol sometimes floats at 14.4 and other times 13.8, totally random.... Must be the BMS and the DC-DC charger fighting for control :)

[@TheMusingGreg]

Haha yeah it's best to just have one electronic brain on the job I think! I would initially agree with you re the BMS except iTechWorld recommends a lower float voltage. My guess is that if you did 14.4 volts the whole time, it will rely on safe mode preventing the battery from over charging, but if it floats down to 13.5 then it should be able to still maintain a full charge without needing to activate safe mode. Those safety measures really should be backups, as opposed to the primary measure being relied on to prevent overcharge every single charge.

[@holgermuller2987]

Very nice vid Itech…. Seriously ?!? The app seems to have still more bugs then a dog flees…. I am still monitoring my system with the Victron shunt and app.. Nowadays I guess all underate their batteries to have a safety margins for the warranty period. Quote 100A capacity battery drops to 80A capacity within 2 years ask for warranty….. Cheers

[@TheMusingGreg]

Thanks mate yeah hopefully they can sort the app promptly. The Victron app seems solid to me so hopefully they use that as a model.

[@ArgonsGas]

Pretty disappointed the battery doesn't use the shunt to give the SoC

[@TheMusingGreg]

Yeah so was I, I mean why wouldn't you use hardware that's sitting right there? But that's why I'm hoping they can fix it with a firmware update. This is just my opinion, but I'm wondering whether they were just trying to throw something together quickly to meet the new Australian standards on lithium batteries which require some form of battery monitoring available. But even then, they'd already done the work to design the 500A battery monitor so why not just reuse it? More questions than answers unfortunately!

[@maddawg9116]

I call these Depth of Discharge cycles ratings BS. Only thing that matters is warranty periods. What's the point of rating10000 cycle of DOD at 100% when the warranty period is only 2-3yrs?

[@TheMusingGreg]

Yeah that's a very valid point mate. I did consider saying that myself in the video, but being an unprovable opinion I just stuck to what I could prove. I hope it's more than purely marketing, but I'll keep an eye on that as I use the batteries myself
