I DON'T have the answer but I'm asking those who do have these new beaut blue cells.
We all know how ebeey and Al -i and other places love to add 50 percent or double the value of panels, batteries and say things are mppt when they are not yada yada. We measure panels truthfully by looking at the size in relation to a very decent brand like sharp etc. People here read the weight of the AGM to see if it really is the power rating that they claim.
All over this forum are the lovely blue cells. The price and the power looks great. But even when paying these cheap prices we want to know that they are going to last. Dozens of guys here (Australia) in Rvs have had their winston cells here going well for 7 years so far. Most have no loss in capacity yet. So I am going to compare the weight and size of Winstons against the Blueys. (if you own these lovely blueys please don't get upset - I have come to no conclusions - Im just asking right now)
200 amp/hour winston cell
Specs taken from here https://www.ev-power.eu/Winston-40Ah-200Ah/WB-LYP300AHA-LiFeYPO4-3-2V-300Ah.html
Weight : 10 Kg
Size : 306mm X 55mm X 363mm = 6.1 million cubic mm volume
190 amp/hour bluey cell
Specs taken from here https://www.aliexpress.com/item/330...&terminal_id=f75f4908058e44a68c6bcbf5ee688846
Weight: 4kg
Size: 174mm X 54mm X 207mm = I.94 million cubic mm volume
So the new blueys are less than half the weight and less than a third of the volume of a reasonable battery that is only 10 amp/ hours bigger.
1. When did this quantum discovery of all this power for half the weight and a third of the volume happen/ Who did it? When and how?
2. Has anybody tested the capacity of their 190 ah blue battery? Id love to know what you found!
3. Did the battery stay cool during your discharge test?
The winstons can be dicharged at 3C (many do this here) and the blueys at 1C so there is a BIG difference if you are going to run hungry appliances like big inverters. This difference is similar to the volume difference.
I'm not like some people who say - "Oh it will all be outdated in 5 years what does it matter?" Many of the things I own are 15 to 40 years old even with electrical stuff. I'd rather pay double for something to last three or four times as long. Determining that is not easy at times. I guess we won't know for some time how the blueys will fair. It's not easy to tell. I can get heavy AGMS now for very little and some even free. If I am going to spend $2000K on new light batteries that I treat well then Id like them to get at least 12 years plus. It's a gamble for sure.
I have no clue about the new blueys but I want to believe they are awesome. Any light that anybody could shed on the above anomaly would be appreciated. Any info you can tell us about your new beaut blueys would be appreciated.
