Great video showing older battery types. A LFP battery with 4 cells and BMS is ideal for 12.8v radios. You can chose the capacity, 25 ampere being small and light weight.
Excellent video, lots of very useful knowledge here. Thank you for making it! I started buying 1.3AH 12v SLA batteries for about $20 each at the local car parts store where we get different battery types. I like them because they are low maintenance and user tolerant. I think as part of "go kit" (floods and bush fires here in Queensland) the choosers of kit might be us, but the users could be friends and family, including the young and non-technical, operating a QCX or QDX on our behalf, so safe reliable power is essential. The other nice thing about SLABs is that they were everywhere when off grid electronics were deployed - industrial building alarms and things - and used during power outages and have long term trickle chargers. If things got really bad, chargers and replacements could be easily found. "Go kits" may not need to move anywhere, but they need to work, often in harsh settings. Something could be said about connectors for car batteries, but this comment is long enough already. :) (Maybe we should have a video about power cables?) Thank you again for another wonderful video. I am sure most of us here really look forward to them. 73's, VK4SSE, Rob
4 cells LiFePo4 assembled with a BMS and the question is solved. Stable nominal voltage of 13-14V, save and with endless lifetime. Better than LiPo that doesn't fit the nominal required voltage, dangerous, and with limitid lifetime.
Great vodeo as usual for you, but what I appreciate most is your statement regarding safety. I.e., never leave a lithium-related battery charging unattended, NEVER! Thanks for stressing this important safety issue in your video. 72/73 de AE5ZX
Hi Gil from the North East United States. I was wondering if you could answer this question I have a 6,000 milliamp 22.2 volt lipo battery I'm looking to use this on my Clansman RT320. Will this radio be able to run on 22.2 volts at 6,000 milliamp hours? Thank you in advance Roy C.
5S or 6S? It will run but you will not be able to use the full capacity of the battery. Not sure what the m8nimum voltage of the radio is, but you probably will reach it quickly. LIPO cells are 4.2V charged, so it's 5S at 21V or 6S at 25.2, not 22.2... 6S would work much better than 5S...
Thank you for your help with this question I wanted a 7S and charger but there hard to get everywhere I searched they want big money for them not including a balance charger. I have a balance charge but it only charges up to 6S.
6S should do it, much better than 5. You'll get 25V. 3.7V is the nominal per cell voltage, but charge voltage is 4.2. Make sure you do not discharge below 3.5V, 21V total. Watch out, they drop suddenly... I use a hobby RC voltage alarm...
This topic applies to all ham radio operations. Another great video!
Well explained battery review, thanks Gil!
Glad I found your channel, great insight and information!

Great video Gil. Too many people are not aware of the dangers of batteries. Thanks for the warning.

Couldn’t agree more.

Thanks. I learned that from the FPV drone community...
@@RadioPrepper Great! Now all I have left to do is to spell video correctly. 😀
Ótimo vídeo.
When using 8 X EBL 2800mAh Ni-MH batterires with a QCX-mini, how many hours can you use it without charging the batteries again?
Hi, I haven't measured, but I would expect quite a few, all day probably. Say 2000mAh useable /80mAh=25Hrs.

@@RadioPrepper I just ordered a alarm. Thank you for the additional information. It's definitely helpful.
