Fred. Great video and interesting to see inside the radio. It's quite an eye opener to check many of these aftermarket Li-ion batteries before fitting, a lot of them are some way off their stated specifications. Glad that you got there in the end. 👍
"Fred" -- I've been trying to decide whether or not to buy a similar radio and their custom Li-po battery is the #1 negative issue for me because they have a limited lifespan, yet are not designed for the user to easily replace. It is designed obsolescence like cell phones. What I'd like to have is a Malahit (Malachite) radio that uses standard batteries that are easy to replace. My preference would be 18650 Li-ion. But AA NiMH would also be fine. And I agree with you the current models of these SDR radios are way over-priced.
FRED. Nice One Fred! I watch all your videos all the way through till the end. Appreciate you making these videos. BTW Lipo Batteries usually ship with 3/4 maximum Voltage. Fully charged your battery will be around 4.2v & minimum Voltage would be around 3v, SO the latest battery was in a good 'Transport Voltage.

If the battery is protected you can short it no worries. It’ll just shut down. Edit: also at 0v that battery was DOA and may have had an internal drain. 3.3v or so is about empty for a lithium cell, 4.2v is full. Fred.
Hi Fred, great video ... Lithium batteries have a nominal voltage 3.7V (Generally the voltage they are happiest at) and the best voltage to be stored and shipped at. Charged voltage should be around 4.2V and fully depleated around 3V - 3.2V. If a bettery isnt going to ve used for a good while, aim for as close to 3.7V as possible. I do this with my EBike battery through the winter Great video Graham
Fred! You can usually recover a drined battery by hooking up a current limited power supply and putting a minimal charge into it. Not worth it this case as it was a new battery and under warranty. Anyways cheers and I do have to pick up one of these radios.
"Fred" I'm surprised that you killed the original battery, as when the battery reaches the charging voltage, it won't charge any more. I guess the charging voltage is quit a bit higher than the actual 3.7v cell voltage. Good video and glad you got it fixed!
Hi. Yes normally the charge circuit will restrict the amount of voltage at 4.2v and then shut down when fully charged. For some reason it seemed to have failed.
Fred. I watched till the very end! As an owner of a HFDY "branded" Malachite DSP1 V3 running on firmware 1.1D with a dodgy tuning encoder that heals temporarily with a spray of quick drying contact cleaner, I'm wondering if it's worth going for the expensive Malahit DSP2 or the quirky, but affordable Deepelec 101 SDR with the wider TFT screen, 192kHz spectrogram . Your suggestions would be awesome! 🙂
Fred , I have recently bought a President Randy 3 I consider this one of the best current hand held cb I Also recently bought a President Grant2 premium another fantastic radio 👍
If you get a Li battery that will not charge via its charging cct , check the battery directly. If its reading very low try connecting to a bench PS and give a small charge and if the battery takes a charge try and reconnect the charger CCT it works for a lot of batteries. I now i have redone many batteries that way . The capacity may be down but it might get you a temporary fix for a while. The batteries should be shipped with about 75% charge. Your BMS controller should not allow over charging or discharging and if it is not, i would replace it as it might fry another batteries. Fred..
I like the little IO board yours has for encoders and power switch. I dropped my malachite about 3 feet, in a case, and managed to rip the power switch and a 1/2 inch the trace off the board.. Wasnt too bad to fix but idk about next time, might have to remove the screen to find more trace lol Does yours have encoder skip issues? Im guessing yes but the IO is a bit different. I posted a video showing how to upgrade the clones with the newest patched skip fix firmware. Not sure if youre interested but its on my channel.
Thanks Shane. Ive found a cheaper better Malachite version with a bigger battery. Its on test at the moment and a video will follow in a couple of weeks.
@@CB-RADIO-UK I've been interested in these for a while now, as well. But now I'm interested in the ATS-120! So many cheap Chinese radios, what's one to do?!
Fred I stayed! What you can do in future is bin the battery and install a 1/8" jack socket, the jack plug soldered to a AAA external battery holder and use 3x rechargable AAAs at 1.2dcv = 3.6v. This is just my thoughts??
That narrow little PCB under the Kapton (yellow plastic) tape is a protection circuit. A 0-volt LiPo battery would be VERY bad, but when you measure that cell you have, you're measuring AFTER the protection circuit. It's not (necessarily) a bad thing to see 0VDC out of that. It just means the circuit has tripped. Maybe it was accidentally shorted while being assembled, or it has been in storage long enough for the voltage to drop below the cutoff. Usually you just need to give it a charge to reset the circuit. I personally would give it a manual charge on a bench power supply, and measure a full discharge cycle. If it still holds a charge within spec, I would carry on as normal without concern. One would hope that QC would keep you from seeing those issues, but I tend to go for the cheapest option!
If you like, you can actually poke the leads of your meter through the tape, onto the pads where the cell itself connects, to measure the cell directly. Then just a little squidge of electrical tap to cover it back up, and it's like it never happened.
As in sure you know, if they drop too far bellow the cut off, they won't charge through the regular circuit and need to be 'Jump-Started' by bypassing the protection circuit. Jump start with another battery that's fully charged. Connect like a car battery positive to positive and -ve to -ve for roughly 10 , 20 or 30 seconds. Or as you suggest a bench power supply.
@@AdamDeal-KF0PRI Almost everything comes from China these days... the big difference between good and bad is not where it's made, it's how much time and effort they put into quality control. No one thinks iPhones are cheap crap, and they've been made in China since the beginning. Thanks to the return policies from places like Amazon, I'm usually willing to roll the dice and go for the cheap option, myself. But for those who don't enjoy tinkering, not to mention those who like to support local businesses, I certainly understand those who disagree with me!
Can’t I simply say I watched it to the bitter end ? May have been wiser to test batteries with a bench supply and monitor USB charging current with either an appropriate USB gadget or a clamp meter.

I ve never seen one on standard battery. Best i can think of is to simply connect a 5 volt power pack via the USB C which give a much longer run time.

Fred just a point the storage for a single cell lipo is 3.6 vdc. if the cell drops below 3.0 volts the battery will be impared.
