Power Sources for Portable Operation
2019-11-20 I got the miady 6Ah battery pictured below this past Saturday via Amazon. After charging it up I connected my Xiegu G90 to it and went about my normal operating which involved quite a few hours a day with the rig on and several, mostly CW QSOs each day as well as some playing with antennas, etc. Most QSOs were at 20 watts. Today, five days later, it shut down. Not sure if that is good or bad performance for a 6Ah battery but it did work! Seems for the $33.99 ($.47 per watt/hour) price, compared with $81.74 ($1.50 per watt/hour) that I paid for my Bioenno 4.5Ah battery back in February, it might be a good cost saving option for portable operation.. The charger I used is also pictured. I did have to insert a pair of power pole connectors in the charger output cable so I can use it with both batteries. The Bioenno has a special charge connector which is what the charger came with. With just the non-extensive testing I've done with both batteries I can't say whether one is better than the other. But the price of the miady certainly makes it attractive if it turns out to be a good battery.
Also pictured is a 7Ah SLA battery. At half or less the cost than the miady battery it is an excellent choice for portable power if the 5-1/2 pound weight is not a problem. The miady weighs just over 1-1/2 pounds. All three of them will power most QRP radios for many hours.
