With all the talk from guys about batteries and charging, I thought I'd mention a deal I ran across. This is a great tool at home in the shop, or out on the water. You can peak your batteries by temp and KNOW that they are charged to capacity and you can check temps on your packs, motor, esc, etc. after every run to check your setup. This one also has a clock built in as well as a stop watch which comes in handy to track run times and it defaults to the clock and ambient temps to help in setup as well...not to mention reminding me when to get home to momma (read:girlfriend) on time.....

I must have caught mine on sale the weekend before last as I paid $9.99 for mine, but I think it is still worth the $19.99 internet price if need be. I have been using a $200.00 Raytech previously and the only difference to me is the cheapo here has alot more features......
