I also use a clip on glow starter that unscrews to change the battery. For my starter I use a 19v drill battery. Smaller than lead acid and lighter and easier to charge. Several guys at the field do the same and have had no issues with starter life. I just bought a Life receiver pack and it seems to last quite a while and price was reasonable, although I also fly electric so I had a charger. I use a large syringe to fill my fuel tank because I like to keep my fuel system as clean and simple as possible.
