Absolutely and thats a good thing too.

For many years I have been a very happy customer of Octopus Energy, due to a recent spat all started in another forum, I started looking round and I cam across T^omato Energy. I'm sure it's a relatively new company but their tariffs are incredible, well worth a look. Heres their prices I have...

And then you go and spoil it o_O

BMW have announced a recall of 432,000 cars after a driver tried to use the indicator.

Absolutely agree, no problem at all. Can you see the BMS parameters? Some won’t start balancing until a threshold voltage is reached, typically around 90% mark 3.35v or thereabouts.

I wonder why the dip and kick in cell voltage shown between 99 and 100% isnt reflected in the curves for 12, 24 and 48v packs? 20% and 95% does keep you away from either end of the discharge curve but it has little to do with the life of the cell. Time above 80% is the start of the accelerated...

There would be greater losses in the wiring, the need for thicker cables and frankly, it's not worth it. SWMPSU's are so efficient the losses are minimal

What I have found out is the 100% at the top only makes a small difference to longevity of the cells and it's only whilst it is at 100%. As soon as you start taking energy from it the damaging process stops. I charge mine up to 95% and solar then quickly takes it to 100%, I havent figured out...

Yep, been there for sure. FWIW, grade B cells dont make grade A because they have a higher internal resistance and/or lower capacity. None is really critical for home battery system and a decent active balancer can keep it all running nicely. You will probably experience a slightly lower...

John Ruskin Said: “It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money - that's all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law...

Aye the 600v will hurt, the danger with the high voltage and high current from the batteries is of course the ability to cause real damage in the event of a short or earth leakage. I'm comfortable with my 50v, that only gives a bit a tingle LOL. I do have a video somewhere from EVE where they...

I commissioned my DIY battery on 24th December, 2022 so that I could hopefully cook Christmas dinner off grid. I did achieve that much to my surprise, there no hiccups along the way it all ran smoothly. We ran out of battery power at about 21:20 on Christmas day having had all of the family...

I purchased my cells in May 2022. The numbers seem a little odd there, 6 modules wired in series at 50v each would give 300v into your inverter? A module to have a terminal voltage nominally of 50v would need 16 LifeP04 cells per module, have you got 6 x 16 = 96 cells in your system? If the...

Further to the above, attached here are PDF's of the battery housing, anyone is free to use them for personal use, I have also put the dxf file (battery module.zip) in there for import to CNC machines laser or router. The PDF's are all full size so they can be printed, pasted onto wood / plastic...

I did use one battery module on my Bailey Senator Wyoming caravan, it gave me a true 280 a/h capacity with the same weight as the leisure battery it replaced. They are easy to put together and in my caravan version I built the BMS system into the module. Thank you for your kind words. Try as I...

It depends really on how much you want to spend. A 3.6 kW Hybrid Inverter will cost you circa £500, you may find some at about 2/3 of that price used or end of line. A battery such as Fogstar that would give you 2.7 kWh storage would cost around the £600 mark. The battery can be taken away and...

We would really need to know more about the requirements and the shed. For example does it require continuous power or only when occupied? Could a portable battery system be used where you take the battery away to charge it up? If you want to go the solar route, does it need more power in winter...

Each to their own, I'm only making people aware that it's no longer essential for some energy suppliers. There are many people like me that do though. I'm an apprentice trained, ex steelworks electrician now retired. I have the technical know how but obviously Im not a member of any of the...
