I have two maplin 6v 4.5ah batteries wired in series to power my dashcam while parked.
The batteries are similar to this one :

Been looking into these batteries from dewalt standard 18v battery but has an output equivalent to 54v.

Hi guys Merry Christmas
I have an E Prance WIFI door bell system but the batteries hardly last a week, the bell takes 3 x AAA batteries,
Can I connect a mains to 4.5 volt DC transformer onto the bell without blowing the thing up.
Many thanks

Hello all, this is my first post so please don't grill me too soon ;)
So I've finally got mains in my shed after a few years of using 12v lighting and rolling the extension lead out when required. For a year or two, I have been running 6 x 4.5w LED clusters as main lights using a pair of 12v...

Evening all.
My friend has asked me if he should buy 3, 4 or 5 Ah makita batteries. All my batteries are 3Ah so I do not feel equipped to answer him as I have no experience of the others.
I am completely happy with the 3Ah ones, however what do you guys think?
Is it better to have the 5Ah as...
Been out of the loop for a bit, am I right in assuming that batteries for a domestic self consumption situation are 5%?
Also for off grid systems?

New technologies have now been developed to tackle two of the world's biggest energy challenges -- clean fuel for transportation and grid-scale energy storage.
The researchers described their findings in two studies published this month in the journals Science Advances and Nature...
Researchers have created a new silicon-tin nanocomposite anode that could lead to lithium-ion batteries that can be charged and discharged more times before they reach the end of their useful lives. The longer-lasting batteries could be used in everything from handheld electronic devices to...
I am in the process of designing a system for deployment in Southern Africa and looking for some help/input from fellow solar installers and enthusiasts. Their grid is somewhat hopeless and is often turned off due to lack of supply - load shedding. I am looking at the possibilities I have ahead...
Hi all, I'm looking to buy a decent (not overly expensive) combi drill. Any recommendations and ideas of what sort of price I should expect?
Thanks in advance
Hi,
I hope this is the right place or even forum to get the answer to this.
If an electrical product would normally accept 6 x D (LR20) batteries.
And I wanted to extend the time that the unit went before needed to have it's batteries replaced.
Would adding another 6 batteries to the existing...
Hi all, just wondered if anyone has had a similar issue with their 1552 or 1553 Megger mft ?
noticed the fault started just after I changed the batteries, fuse logo came up on screen so changed that, now it works, but when testing live circuits it completes the test, but then within a few...
Hi folks, what is the score now with HSE etc and storage batteries on a solar installation? I know banks of storage batteries were a big no-no a while back, I help out with a wildlife charity who have a completely off grid solar set up with approximately 1500ah of battery power @24volts, I'm...
I have a couple of questions about testing and maintenance of emergency lights.
I have been told that if the LED on an emergency light does not work it must be considered “Failed” and the fitting replaced, but when reading up, I cannot find any regulations or guidance to suggest this is...
Hi,
I bought myself the LED Lenser H7.2 as I got a pretty good deal.
I noticed they sell rechargeable power packs with charging cables, if i bought myself the pack and cable would this work the same as the H7r.2?
I may be being stupid i know its not the same but i was wondering if it work the...

Looking to get a new combi drill around the £300 range, so many options it's hard to decide what's the best, have a dewalt at the moment but it's a cheaper version and useless, I like the look of the xr range though. Had a Bosch which was decent and have heard good things about Milwaukee.

Hi,
I have a Fluke MFT 1654B, I have had this one for about 3 1/2 years now, ever since new, when you zero the leads, regardless of if its the blue red or green leads, which ever combination, they always come out at around 0.20 Ohms.
I have periodically had issues over the last 6 months or so...
