Have you considered looking at building an air lift pump. The cost would be tiny. You would need to pump into a storage tank. It works on the basis that you pump a constant supply of water in small volume into a header tank. A small solar panel and a 12v aquarium air pump are the basic parts...

There are a range of inverter chargers. So the features vary between the models. I can tell you that the one I purchased from Amazon UK didn't have the remote switch plug but I just extended the On/Off button mounted on the case to a generic inverter switch I purchased off ebay. The generator...

I can see the idea behind the changes but improving the packaging and keeping the original design would have been a better idea. Alternatively they could have made the terminals wrap around the PCB and a bolt hole that passed straight through the PCB. This new design limits the torque you can...

Well the fake tracking has been accepted by Aliexpress. Even the tracking on Aliexpress shows my order never came near the UK-England. Aliexpress have still sided with the fake seller. If you put the same tracking number into any other parcel tracking websites it clearly shows the tracking...

I've only just received mine. Try triggering the low temp sensor and put a multi meter on the square PCB terminal. The 4 points in the picture on Aliexpress are all connected together by a square bolt on lug/plate.

If you are going to open a case with Aliexpress/Paypal/Credit Card, just remember to be polite. Your dealing with a person that has to deal with complaints every day. Yes it is frustrating and understandably you as the buyer are upset because you paid out a lot of money and waited 2-3 months...

The reality is you cant chase debts in China unless you have serious connections in the Chinese government. Even companies moving manufacturing to China dont have any legal right. If legal cases are taken to court inside China by None Chinese origin citizens (foreigner's), the courts always...

You are partly correct. PostNL is usually Air Freight. I get plenty of items from Aliexpress delivered to the UK-England via PostNL. In fact i have just had 2x JBD 200A BMS boards delivered today via PostNL. I have had heavier/larger items via PostNL that were transported by ship in the past...

Norton cranes, Staffordshire is an Amazon bulk warehouse that deals with retailers stock directly on pallets. I would be grateful if you can let me know if the inverter does have the ports for the remote to plug in and the green plug for the auto generator start.

Did you order from Amazon or Vevor? I found a handy tracking website. Iv have got 8 or more items coming from China on different ship, planes and items that have already entered the UK. All with different delivery companies, that often changing to different companies once they enter the UK...

Yes mate i will put up a link to the remote panel or share the contact details if this pans out. The manufacture is putting a sticker over the remote connection port, which says contact the retailer to purchase the remote panel. So the manufacture clearly want to sell them. It seems the...

Not a project for a novice I don't want anyone getting an electrical shock After digging around online i found these server power supplies are designed to supply just over 15v if you bridge two of the connectors. Then you have a second pair of terminals you can add a 10K Potentiometer to...

I have had a couple of messages back and forth with the retailer/manufacture and i'm waiting for a price for this 3000W inverter and a price for the LED &/OR LCD remote panels. Sometimes it's like pulling teeth to get answers to simple questions. Or get prices for single orders. You would...

The PC (server power supply) i have is 12v at 62.4 amps. Rated at 750W. So i should comfortably pull close to 45A-50A at 14v. It's a reliable and clean power supply that i used to power my Ham radio until i got a dedicated power supply. Now it's sitting in the cupboard collecting dust. So it...

Is there any chance you can open up the regulator, so we can see what components they have used? I would order one rom China but its going to take 2-3 months for delivery to the UK and I already have the 65A PC power supply. Small components like the voltage regulator and the display i can buy...

After noticing this adjustable power supply on Aliepress, that is clearly made from a PC power supply and an adjustable DC regulator. I was wondering if anyone any idea which regulators would i need to buy? I already have a PC power supply with an output of 65 amps at 12v. So i just need to...

None of the listings iv seen state any more than 70-75 Amp charging. Yes Aliexpress has started adding 10% on most order. Even items under £15. I ordered a few different BMS boards ranging from £60 up to £140 per order and they all had 10% (VAT) added to the order by Aliexpress. They call it...

Keep your eye on FB because they pop up on there cheap on a regular basis. I think im going to custom build my water tanks. That's for a different forum. LOL

Have a look at https://www.superlecdirect.com/ at their Tri Rated cable. When you see UK companies use words like over rated/over sized cable, there is a good chance they are selling you metric sized cable that they are buying from Superlec but they are charging twice the price. The same goes...

Just remember you can always do a bank clawback if you pay by card. (if the inverter arrives broken or breaks later on) I read there is a power saving mode (standby mode) that uses 5W and Standard power mode is 20W. I'm not saying those figures are correct. Personally i plan to turn it off...

Cheers for the link. Yes i'v spoken to Vevor and they have stock in their Czech warehouse. Vevor don't have the best reputation for customer services but the same can be said for many retailers on Amazon and eBay. At least in the UK we have an option to ask the bank to claw back any card...

When you consider Shore power on a campsite will have an RCD. My van has the correctly sized RCD breakers for the 240v shore power/Inverter input. The inverter has two trip switches. Every 240v socket in my van has an RCD. The two earth/neutral connections will feed back to the shore power...

Sorry my mistake. I meant Low Frequency but I was typing at 2am in the morning and then i went to bed without posting my comment. Then i woke up this morning and started up my PC and noticed i hadn't posted the comment. I would connect my MPPT directly to the battery. (Not to the inverter) So i...

You have the option for shore power input, solar input and wind turbine. Because the inverter is a LF (edit) unit it can have multiple inputs, plus many LF (edit) inverters will also charge the battery while plugged into shore power. When you plug into shore power the inverter has a bypass...

I did look at the weight. 25.2Kgs (55.5Lbs) That looks about right for a 3000W HF inverter.

They say it's got a 9000W surge and i'm never going to use much more than 2000W at any given time in my van, leaving a healthy buffer of 1000W. Plus it charges at 75A from shore power at 14.3V. So i'm hoping it should last a long time (fingers crossed) At that price I think it's worth a punt...

I was wondering if anyone had any experience with this 12v 3000W (230v-240v) inverter from Aliexpress? https://www.aliexpress.com/item/4000091920526.html?spm=a2g0o.cart.0.0.2dda3c00krhkRs&mp=1 Looking at the spec the charging voltage looks to be geared towards charging Lead Acid batteries and i...

A little update. Had a message from JBD that stated "The heating pad has a power of 100W @ 12V Max 10 A at low temperature" I have ordered two 10W silicon heat pads that i will place on some foil bubble wrap (under the cells) to spread the heat more evenly under the 4 cells. I plan to set the...

Looking at the video clip on Aliexpress the square pad next to the bluetooth looks like it's the negative connection to attach the heat pad. It's marked H- (heat pad negative. The red and black wires are marked (Discharge Switch Port) but no idea what they do?

If you wanted/needed a larger heat pad you could use the 12v 5 amp supplied to trigger a relay, which would let you run any sized heat pad you wanted.

Iv ordered one of these myself. I spoke to the retailer who stated the 2x heat pad outputs are rated for 5a. I'm assuming a nominal 12v X 5amps = 60 watt for each silicon heat pad? I have ordered two 12v 50 watts silicon heat pads to stay under the 60w rating.

I have ordered this 8s to 20s 300Amp BMS with Bluetooth https://www.aliexpress.com/item/32997552090.html?spm=a2g0s.9042311.0.0.7a444c4d6nskZw I will be using it on an 8s Lifepo4 pack. My first question is, will this BMS connect to the Bluetooth out of the box? (once it is connected to power...

Can the Epever temperature setting be accessed using the phone App? Or does it need to be connected to a PC?
