Andy, Sounds like you have made a career in offgrid power, something I have only dabbled with.? The earthship must have been a major project and a big learning experience, I was looking hard at that

Don, RC batteries aren't unsafe because they don't have an i ternal BMS. In RC use, management is split between the charger on the ground (charges, controls voltage and current, and balances). In the

What needs to be respected is written on the label... Lithium tech allow a significantly greater amount of energy to be in a far smaller and lighter package.? And if not managed they can deliver it

The common brick lithium battery packs are the least safe because they are very vulnerable to abuse.? That is:? over-charging, over-discharging, shorting, puncturing, and failure to balance the

Hi Thomas, Any news on Sbitx stock availability? Thanks, Amol

Also, note that when clicking on "Battery" in the upper left of http://www.powerwholesale.net/, ( http://www.powerwholesale.net/, ) you are presented with the following choice: Category Battery Li-ion

Curious, we wound up at the same vendor. From http://www.powerwholesale.net/about_us.html "About Us Docan?Technology (Shenzhen) Co., Limited is a famous OEM battery factory with providing battery

Andy, I looked at your bio on QRZ.COM... Very impressive and thought inspiring and it encourages imagination. Thanks. Bob KK5R

Hi, Here are some resources for remote rig control. The best package I've seen seems to be this. https://rigpi.net Supposedly the source code is on Github, but I only found an empty repository for

Lost a reply on the phone...let's try this again on the laptop... With respect, Jerry, "common usage" depends on the group being surveyed.? For the general public, I agree that "lithium ion",

The 2P16S bank of EVE LF280K LiFePO4 prisimatic cells here replaced a 6 year old bank of eight Trojan L16RE-B 370AH 6v flooded lead acid batteries. Those L16RE-B's were quite good for lead acid, the

Hi Allison, I have been reading the instructions. ?The instruction document has been added to since it was first posted and my guess is the project will accelerate after the holiday but I thought I

I've used LICC? (carbon cobalt) those are some of my oldest 18650 cells (most are 1800mah). I have an abundance of Lipo 18650 form most are the 2200 and 2800mah size. I also have Lipo pouch cells,

Andy, No real argument, I agree with most of what you say. 'Common usage' is a useful thing to be aware of, as this is how most other people describe what they are doing, and even how manufacturers

Hello! I am looking for a software through which I can do both control as well as audio stream for uBitx. I want to access the radio from outside my house as well as talk via it. Just like in wsjt-x.

Yes, cobalt levels in some LiCoO variants are decreasing. The relative safety standings remain, however. 'Common usage' isn't a useful metric. Folks interested in selecting a product within a family

Hi All, I am curious how the evaluation of the PA MOD plan is progressing. ?It appears that test kits are being evaluated (idocumentation updates) by a select group of individuals. It would be great

You are correct, though some of them don't have much cobalt these days. A web search for "lithium ion vs lifepo4" shows that common usage is to just say lithium-ion if it isn't LiFePO4. Metal cylinder

Mike, Every cell chemistry in the lithium family is "lithium ion" and "lithium polymer". They all use a polymerized electrolyte, and all rely on lithium ions for charge transfer within a cell. What
