I started using LiFe batteries about 6yrs ago, and power all my small glow plane recievers with them. My first LiFe compatible charger was one of these...It will charge any type of battery, including LiPo, NiMh, NiCad, etc.. and gives great data to log your battery use and condition..It's AC/DC and will work at home or the field.

I've moved up into a 4-port charger a year ago, that will charge 4 batteries at once, which was quite a bit more expensive. I wanted a charger that would charge my dual packs in my HV(LiPo) powered giants but I still use the small IMAX for single batteries. The four port chargers usually run over $200 for a nice one. I found them IMAX was a nice starting point back in the day when I started using LiFe batteries. I also have an old Triton that won't charge LiFe's, but is compatible wtih LiPo's, and other batteries. With new battery technology, everything gets charged in 1hr... that's it.. for any type of battery I own.

For my starter, I use a 2100mah/3S(11.1v LiPo) battery clamped to my sullivan starter, and I've used it on most any glow engine up to about a 1.20 four-stroke, which it starts very easily. Really I only use a starter on my four-strokes, my gas engines and small two-strokes start easily by hand. I've found it's just safer using a starter on four-strokes... and they start with just a quick bump.

I use the same type of 2100mah/3S LiPo for my small glow-fuel pump in my flight box... just stuffed down in the same battery hold area that I kept the monster 12v hobby battery.

There's many different batteries that will work, and many of us do things differently. There's no wrong or right, as long as you believe it's safe and affordable, and do your homework on battery safety and charging. It's nice not being attached to a flight box, and not having a ton of heavy batteries to carry. The LiFe receiver batteries are the best thing since sliced bread... lightweight and affordable....and the LiPo's are great when you need some punch to power a starter.
