I have recently got a Sp PD 8X and am looking at using it for a USB charger. I am very close to ordering the sinewave cycles revolution. I like it because as well as charging from the hub I can connect it to a DC source under 50 odd volts and still charge.
I would also like a small portable battery that has about 24 Ah capacity with a 12 volt output with up to 2 amps out. This needs to be charged by a USB charged such as by the sinewave revolution
I realise that eBay has plenty of batteries with totally unrealistic capacities listed so was hoping for a better brand. Ideally I would like to use a LiFePO 4s but realise they seem very difficult to charge. I want it to power a radio transmitter such as the Yaesu Ft 817.
Any comment please.
As Ron suggested, I'd recommend the Forumslader, especially if you need to run 12V equipment, as it has a 12V output from the battery pack. It'll also take input from DC power sources and solar panels. You could upgrade the battery capacity of the Forumslader I suspect, it uses 3 Sony Li Manganese batteries in series. It has built in cell balancing already. Talk to Jens and tell him what you want to do. Use google translate to read www.forumslader.de Jens' contact details are there...
