I'm confused, is a "lipo" battery one using Lithium Ion? I have some of those for 2 Kenwood TH-F6A handhelds. There are 2 sizes of batteries for them. The smaller sized is about 3.125" wide by 2.25" high and 0.5" thick. Its rating is 7.4V and 2000 mAh. The large one is twice as thick and rated @ 3600 mAh. We also had AA battery holders for these radios squirreled away in our cars and backpacks. My late hubby's BK field programmable handheld he bought for volunteer FD use has a holder that uses 9 replaceable alkaline AA batteries. All of these radios last at least 8 hours while they are scanning and transmitting. None have the pretty colors on their displays. I have a home weather station with a thermometer, anemometer, wind vane, barometer, rain gauge and humidity sensor that has 3 AAA lithium ion batteries that only have to be replaced about every 2 years. It sends data in very quick pulses, but is on all the time. When I think of those and look at a receive only radio that is larger than the Kenwood transceivers I wonder why it cannot be equipped with AA batteries, even if they are the more expensive lithium ion type.
I'm not being argumentative, mind you, I want to understand.
Yes they are also lipo the only difference is 7.4v is a 2s pack instead of the sds100 is a 1s lipo pack. Lipo are very similar to li ion same principle design just different material inside. Every 1s is 3.7 volts of power I fly rc planes that I use lipo in and have many lipos ranging from 1s to 6s packs. As long as you always keep each cell at 3.8v when not in use they will be very reliable and last for years. Look into storage charge for lipo batteries.
