Please just some simple replies. (I am simple ?) Portable operating. Batteries. They weigh so much they can almost be useless. I speak of 75-150 lb units like allot of marine batteries. Simple but start lugging them around. I actually tore my shoulder muscles from these things. (I have yapped about this not looking for ANY sympathy but just trying to relate such can be very uncomfortable !!!) There are dolly's and hand trucks that make moving these quite easy but the bottom line there is going to be lifting lifting lifting. No tool to help. Maybe it is in physics but some 'crane' type tool for lifting weighs more than the batteries. Lithium. Until they have smart ones (built in devices so you don't fry them) one can loose allot of money. Then the cost ? I have put these questions out before about specific recommendations but never anything. Like walk into Home Depot and buy ____________ and cost and experience. (of coarse you can buy anywhere) Is there an economical solution ? I see some Lithium's also at 75+ pounds. Could somebody elaborate on the Mighty Max brand and maybe even a choice ? I just mention this brand as it is sold by Home Depot that can have very liberal warranties and especially if bought on THEIR credit card. https://www.mightymaxbattery.com/c585/lifepo4.html As of now I am just looking for a battery to power a 100 watt transceiver out in the woods somewhere. Generators. Lets just talk Honda. (they at least have a reputation) The 1100 model advertised at 1000 watts has receptacles that have maximum ratings at 8 amps. Most transceivers draw 20-25 amps ? For about the same price the 2200 model that weights maybe 60 pounds to begin with and that does not even have a rating 20-25 amps. I'm missing something. I'd guess the 1100 model could be used for strictly QRP ? The 2200 model can run a 100 watt transceiver ? Maximum rating 18 amps. What am I missing ? I have asked in similar threads in past and when zeroing in on somebodies suggestions/experience ahhh what... no email address ? Talking to one person avoids the thousands of different solutions.
