Hello All:
To improve my flying pleasure for the 2020 season, I am planning to replace my battery pack with something that has more power for a longer period of time. I am now using 10 sub c that produce 12 volts for a short period of time. I can get about 3-4 minutes of starting time with .35 engines that turn easily before the batteries go dead. There is no way that this battery pack has enough torque to spin an ABC .40 engine!
What I am considering is using two 7.2 volt li po batteries in series to up grade my starter power supply. These new batteries may be adapted to the Southern RC battery/Sullivan Starter holder. This may provide improved torque and longer periods between charging.
If you have suggestion, comments or items for sale kindly, kindly inform me. I do have a very nice, expensive, battery charger to maintain most batteries.
I enjoy using a cordless starter!
Tia,
Frank McCune
