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

FYI, anyone following this: Walmart has a 2 ridiculously cheap power stations perfect for running a radio/charging your gear/lighting your campsite/etc... https://www.walmart.com/ip/EF-EcoFlow-Portable-Power-Station-RIVER-2-240-243wh-LiFePO4-Battery-1-Hour-Fast-Charging-600W-Output-Solar-Generator-Solar-Panel-Optional-Outdoor-Cam/5478283286?adsRedirect=true https://www.walmart.com/ip/Flashfish-Portable-Power-Station-Mini-Solar-Generator-98Wh-26400mAh-Lithium-Battery-120W-110V-AC-Outlets-LED-Light-Backup-Battery-Camping-Outdoor/371451213?classType=REGULAR Note: the $149 one is marked in watt-hours, and the $69 one is in amp-hours. LifePo cells are about 3.7 volts, so multiply the Amp-hours by 3.7 for a rough(very) comparison. Whether the numbers listed are true? Well, Walmart's better than Temu, but marketing departments are ubiquitous...

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...

Does this apply to all batteries containing lithium, lithium ion and LiFePo4?

Sweet.

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..

My Army Can repeater utilizes a 50A Anderson connector that i can plug into my RV DC source or even to an AUX Plug on my truck tied directly to the battery.. Of course fused at 25 Amps. The cig adapters of today are not designed for large amp draws like the old original style were

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.

DN411 means the same as DPL411.

I, too, am in your same shoes. Being new to GMRS I am totally lost. I am starting to believe that purchasing the Wouxun KG1000+ over the Midland was a big mistake for my skill level. I am totally lost as to how to program in the DPL411 tone for a repeater because there is no selection for "DPL". There however is a choice of DN411.

The DB20-G and the DB25-G are two completely different radios.

It is interesting to me that it took more time to get the DB-20 on CHIRP when the DB-25G has been on it a while. And yes there are a few quirky things to figure out using CHIRP. I have to do a few things different when I use it on various radios but since my background is programming I guess it does not bother me much to have to experiment and get it working after a bit of trial and error. It's what I do.

And that right there is the reason I will never suggest using a cigarette lighter/accessory port to power a 50 watt radio.

A friend of mine tried using his KG-1000G plugged into the lighter-hole in his care and the plug melted and caught on fire.. Not sure why a fuse didnt blow first... Melted plastic napalm got on his had and gave him a severe burn when he yanked-it out in a panic, but the radio was fine...

So everyone is aware; the Hampton West GMRS repeater is in service. 462.575, CTCSS tone is 203.5. There are GMRS nets the first and third Wednesdays of the month at 1930 hours on this repeater. The Tabb Repeater is also up and running, 462.650, CTCSS tone of 114.8. The Hampton East repeater, 462.7000, CTCSS tone 233.6, is currently offline and will be used for disaster and weather reporting during incidents, and could be relocated to Hampton Fore Station 5 is needed. My Hampton portable repeater is deployable and will also be used in specific, needed areas for hurricane and other disaster work. THE WEDNESDAY, JUNE 18, 2025 GMRS NET AT 1930 ON THE HAMPTON WEST, 462.575. PL 203.5, WILL BE A CKECK-IN FOR ALL GMRS USERS IN TIDEWATER WHO WOULD LIKE TO PROVIDE WEATHER REPORTING FOR DISASTERS. THIS INFORMATION WILL BE PASSED ONTO THE HPST. ALL LICENSED USERS ARE ENCOURAGED TO CHECK INTO THIS NET SO WE CAN GEN AN IDEA OF WHO CAN PARTICIPATE AND WHAT AREAS THEY ARE IN. THANKS.

Some cigarette light adapters work OK with some radios; some cause problems, typically noise like whining. I haven't heard of any radios being damaged. For me they mostly work at low power. One issue I know of is power may drop relatively quickly when the car isn't running, so for a base station multiple batteries are a good idea. p.s. any kin to Samuel F.? my GG-grandfather apprenticed under him

Personally I bought a Radioddity DB20G. It came with a cigarette lighter plug. I inserted Anderson PowerPoles into the power cord because I wanted them but in my pickup I simply use the cigarette lighter socket and plug. It’s a 20 watt radio but it does everything I need. It would make an ideal camp radio.

I wonder if I could get away with this: https://midlandusa.com/products/mxt115-micromobile-2-way-radio and this https://www.amazon.com/CERRXIAN-Cigarette-Lighter-Socket-Adapter/dp/B0BGL8ZRCS

I absolutely agree about double checking the legality. Internet has little to do with this though. The fcc simply included internet because it is an example of “any other network.” Originally the prohibition was against connecting to the phone network. “GMRS stations cannot be interconnected with the public switched telephone network or any other network for the purpose of carrying GMRS communications, but these networks can be used for remote control of repeater stations.”* *The above is the FCC’s interpretation, not the actual regulations @Blaise, arguing it’s a mesh, not a network, probably wouldn’t make a great first impression on the FCC. It’s funny though.

You might get away with it is you do not connect the Meshtastic nodes to the internet. I would double check on the legality of this before proceeding if it was me. This is true. But how many "non radio dorks" are willing to compile source code. If this were to be feasible and legal, then it would have to be made easy for all users to deploy. Not everyone is willing to even learn Linux let alone compile code.

And that will make you his favorite fan.

It is, or at least the backlight timer is! Menu setting 8 (labeled ABR - don't know why) is the Display Backlight Timer. If set to 0 backlight is off. Setting are 0-50 seconds, make sure this setting is not at 0.

If you use the libraries, you can get it to do a whole lot more, I'm told. I'm not afraid of a compiler! Every packet has a 237 byte payload, so you'd have to spend a lot of effort hacking the voice data into chunks, then reassembling them. It might work, it might not, but it sure would be fun trying! Also, GMRS data is likely only about 2 kbps, so there'd be plenty of room for at least that.
