The cables on it were decent quality, but pretty short and thin when I got it, and I'm not sure I'd rate their chances of being happy with 200A at 60v for long, but on the plus side, if you're willing to invalidate your warrantee and crack open the case, they're connected to reasonably easy to get to solder pads, so they're simple to replace. I've put 10awg silicon sheathed wire on mine, and the case JUST closes back around those without having to cut any of it away.I bought this out of curiosity just to see what the 12V side of my emergency DIY "Luggable" battery bank was doing under load, and for that it fits the bill perfectly. It's also been interesting to see things like, what my 20A "Smart" charger is actually doing when it enters the different charging stages, and how much 12VDC power my inverters suck from my batterie bank while they're getting loaded up with different 230VAC devices. It's info is also a useful guide when calculating how long a particular device could run before the battery will need charging (Saves me having to run out to check on it every 30 minutes with a volt meter until I can work out roughly what the voltage drop per hour will be).The most I've pulled through this meter so far was 40A at 12v for 7 hours. It didn't complain, and didn't even get that much above ambient room temperate.When I eventually get around to setting up a couple of solar cells and a charge controller for my battery bank I can see myself finding a whole new list of things that this will be useful for.I don't necessarily NEED any more of these, but I'll definatly be keeping some of them from different retailers in my shopping list, just so I can see when they go on sale somewhere and grab a couple more.

Great little tool for keeping a close eye on power to portable radio equipment, shame there the cables aren't slightly longer.

Perfect inline fitting

I bought this to monitor output on a 60Ah battery I had constructed. Whilst I don’t need the 200a current capability ( I should not exceed 30a) it will do the job and was a good price.

This - or at least mine - has a problem whereby if the voltage rises slowly, such as at dawn when it's monitoring a solar panel, it does not boot. You need to remove and reconnect power in order for it to work.In devising a fix for this, I dismantled it and separated the display from the main PCB - 16 interconnecting pins to de-solder, otherwise all the components are hidden. It contains a linear regulator formed from an NPN transistor (BCP56) and a TL431 voltage reference. There is a small surface mount resistor of 2kΩ with the supply voltage minus about 5V across it. This would dissipate almost 1.5 watts at 60V, and there's no way it can do this, so there's no way this thing will work at 60V unless you isolate the supply by removing D2 or R5 and powering it via the aux pins. I wouldn't trust it at anything over 24V, which is a shame, as the transistor is chunky and rated at 80V. (There are also polarity protection diodes but they're only 40V.)The third pin of the aux power input connects straight to the (unmarked 20 pin) microcontroller without so much as a current limiting resistor. This seems terribly rash. It's labelled with what could be a U. Possibly it's a serial data output but I haven't stuck a 'scope on it to check.Note that the 200A current capability is equally fanciful - even the manual admits that 65A is the maximum continuous current. These look the same as ones that only claim 150A...It makes a faint whistling noise. As the regulator is linear, I'm guessing this is the display multiplexing.

All good

Very useful little meter, the display is quite small, and so are the wires connection is difficult without joining extra wire on, that's why I'd give it 4 rather than 5 stars,There's no permanent cumulative wattage feature on this meter, so when the input is turned off, the meter re-sets to zero, which is not a problem, unless you want to monitor solar or wind generation. The accuracy seems good, and for the money, really good value. I use it between a battery bank and inverter, to monitor depletion of the batteries where it works very well.

I use one of these to measure the voltage and amperage being drawn on a retro fitted diesel cab heater I have in my garage and it works great, giving me accurate information at all times whilst the unit is in standby and running, you will not be disappointed with your purchase.

Fonctionne bien, me semble assez précis. Je l'utilise pour mesurer la décharge d'une batterie, mon seul soucis est que le l'affichage s'éteint avec la coupure de la batterie. Une source extérieure (pile) pour l'affichage serait bienvenue. Mais c'est propre à l'usage que j'en ai.

suppert produit

Con questo strumentino puoi sapere finalmente quanta carica (Amp) entra in una batteria e ti fa anche il totale. Lo consiglio a coloro che vogliono tenere sotto controllo le proprie batterie.

Funciona bien

Schönes Gerät. Zeigt mir alle relevanten Informationen an, so soll es sein. Falls es jemanden interessiert, der Eigenverbrauch des -Diymore 200A- liegt laut meinem Multi-lügen-meter bei etwa 12mA gemessen an einer LiFepo4 Batterie mit einer Spannung von 13,4v.
