starter battery
hey guys i have saw guys rig up lipos on there field starters what kind of batts do i use for it
|
RE: starter battery
Any Lipo will work, but I wouldn't use one under 2000 mah or so. You'll need 4 cells, so either get a 4s pack or wire two 2s packs in series and work out the balancing.

RE: starter battery
I would go with a 20C or higher rated battery. A starter on a large engine can pull quite a bit of current. If it is stopped it can go close to 30 amps. A 10C 2000mah battery couldn't handle that too many times.

RE: starter battery
I would never use a lipo on a starter simply because when you have the best performing starter on the flight line it will also be the most 'borrowed' and this precludes you from accurately keeping track of its usage and the risk of destroying those expensive batteries from deep discharge. Something thats very easy to do.
I run my common starters at 16.8 volts with Nimh dual seven cell batteries from 1700mah, 3,000 and 5,000. John |

Hi!
I use a 14,8 V, 2200mAh Lipo battery in my Sullivan starter! |
RE: starter battery
A set of nicad car batteries will do it. So will a cheap set of polys from hobbyking.
|
RE: starter battery
Voltage is king in starter performance so if you opt for Nicd or Nimh use at least two seven cell car packs which is 16.8 volts (14 cells). If you stick with only 12 volts (10 cell) you will be disappointed and have a starter as whimpy at the commercial 12v portable starters. Most of those soon get abandoned.

RE: starter battery
I use 10 cells in mine and it gets the job done on my .40-60 size engines. I could go deeper into a charge if I had more voltage, but I haven't ever lost flight time over it.

RE: starter battery
will this battery work on either my hobbico 180 or the sullivan high tork

No one ever asks for my 12v 7A lawn tractor battery powered starter. Guess that's 7,000 mAh! |
RE: starter battery
:D
Just may be your on to something there Charlie. JB |
RE: starter battery
ok what i am trying to do is make a portable starter with no cords i will still have my one that is ran off of my field box aslo... this one i am making will not be my only one and beside the field i fly it we have like 5 people that fly there.. so i dont have to worry bout it gettin borrowed all the time.... so do yall think that battery will work
|
RE: starter battery
That battery is likely the minimum that will work and still last for a reasonable length of time. A lot depends on how you use your starter. Bumping a well primed .40 isn't nearly as taxing as starting a bone dry 1.20. Just keep the charge topped off and it should be ok.

RE: starter battery
I have been starting my Saito 150 with my 35-year-old Sulivan starter with a 7-Amp gell cell zipped to it. Works fine.
