If it didn't it's burst into flames the 1st time you charged it. They are very prone to thermal run away if unprotected. -

Most LiFePO4 batteries can be drawn down completely without harm. The BMS will protect them from discharging too far. You might have to coax the battery to come back to life if the BMS turns it off for low voltage though. Discharging a LiFePO4 fully does reduce it overall life. But it is still going to substantially outlive a lead acid battery by 1000s of cycles. -

My KG1000+ draws 8.7 amps according to my digital clamp meter. I was surprised it was lower than 10 amps. -

But when even the people who have the copyright on the name Meshtastic say it’s a network, the lone person claiming everyone else is wrong, and that it’s not a network, might have a problem proving he’s right.

That would be a full violation of the eff sea seas rules/regulations. I can't imagine those breaking the law would decide to use these frequencies illegally and for illicit purposes. They should have their licenses takes away. As soon as you here them ID themselves you should write it down and report them. /S

What word follows “mesh” when talking about “mesh networks“?

You know, after I posted that glib reply, I started thinking (which is always super-dangerous, according to some people: People like my wife and closest friends!)... Because of the broadcast nature of LoRa technology, where every transmission is just put out there with the hope someone will help you get it where it's going, I actually don't think it *does* technically fit the definition of a network!

That's the one I bought on Amazon for ~$159 in February. Presently it's $239 there. Nice product. I believe it's being replaced by the "3" model, which is fast enough in a power outage to act as a UPS. -

The little handheld power bricks OP was talking about can often have minimal BMS, if any. Especially if you got it from Ali Express! She's a hard lady to find, that Miss Conception. -

There is a miss conception when people say Lithium Batteries can completely die if allowed to completely discharge. Most Lithium batteries today have a protection circuit that wont let the battery completely discharge.. And most Lithium batteries have BMS System Circuit (Battery Management System) that manages an array of things, charging, bulk, discharging, temperature etc. BMS systems depend on a small amount of battery current to function, else they simply go to sleep and the battery will look dead until the BMS gets enough energy to function. New BMS systems do not allow the battery to completely discharge, it turns the battery off reserving the small amount of energy so the BMS can function. If the Lithium battery looses all voltage due to a completely discharged battery then it needs woken up. How do you do that? it depends on the battery as there are several methods,, a google search for your particular battery will find the answer,, but the most common way i.e. a Power Tool Battery, you take a good charged battery and apply its voltage for several seconds to the dead battery.. That should 'wake' up the BMS so that it can now operate and sense the real charger to talk with and do its work.. a lot of people have thrown away perfectly good power tool batteries because they simply didn't know who to wake them up -

It's most true of straight lithium ion. LiPo is much better. I've seen them run down to 10% or less numerous times and still retain most of their capacity. They don't like it if you *leave* them uncharged, though. More than day or two sub-10% can easily do them in... -

Thank you so very, very much. I deeply appreciate this.

There was some chatter on one of the HAM freqs last night discussing that GMRS was being used by some of the Rioters in Las Angels. Not being close enough to scan the traffic there, is anyone hearing that type of chatter in LA? Just curious..

I have the DB25-G (25 watts). When I plug the cigarette lighter into this the control tells me it is drawing ~35 watts. This cable can connect to a solar panel, so I have a full off-grid set up without fear of burning down the house. Dialing back from 50 watts makes things much simpler. -

I have Dewalt jump packs in each of my vehicles. These are models with lights, air pump, etc. I already have an adapter made up to power my electric jack. Using the adapter it works well to power my radio. Now this isn't really the most convenient power source due to the weight. But jump packs do supply in an emergency. -
