I was using my yaesu ft 897d with an ldg yt 100 and a 11 1v lipo battery both installed internally in the original battery.
													
																	Ft 897 lipo battery. 
									
	
		
	
																	Qso with ct1mh as a chaser for beaches on the air on 30 january 2016. 
																	The fnb 78 4 5 battery however sets you back 124 around 100 and bear in mind you probably want need two and also need a specific yaesu. 
																	The rig is very portable and the internal batteries are most convenient as you don t need any separate power supply. 
																	13 2 volt 4500mah rechargeable ni mh battery for the yaesu vertex ft 897 radio. 
															
													
									
	
		
	
																	Not an issue for me. 
																	In this video i open up the radio to install a new lipo batter. 
																	Even 4500 mah is a large capacity ft 897 needs more than 600 ma on. 
																	Yaesu ft 897 can operate from two internal battery packs for portable use. 
															
													
									
	
		
	
																	Recharges with original factory charger. 
																	These are 4 cell batteries that have the right voltage range required for the ft 897d and ft 857d. 
																	Internal batteries in the ft 897 i liked operating portable with my ft 897 with its internal fnb 78 battery packs. 
																	If i was powering an ft 817nd i could have gone for a 3 cell lipo battery as the ft 817nd doesn t need as much voltage and just wastes the rest in heat. 
															
													
									
	
		
	
																	At first i wanted to buy a ft 817d radio but as my ft 897d can hold batteries as well and power can be set as low as 5 watts i decided to first upgrade my ft 897d with one or two battery packs.
