Cordless String Trimmer
Wolvenar:
Figured since I had to get it out today I would take a pic
ChrisOlson:
That looks like a 24 volt one. Mine is 12 volt. What does yours have for a battery in it?

Wolvenar:
Yes it is, 24v and amazingly powerful for a battery operated trimmer.
As far as the batteries, I do not remember the model but there are 2 12 volt SLA in it.
I might open it up one day and see again just for the heck of it, fairly easy thing to do.
ChrisOlson:
Mine is very powerful too - easily as powerful as a small gas one. I think the key is in the motor. I took the screws out to see what sort of motor it has and it reminds me of one of those electric model airplane motors. It's got a neo magnet field with brushes and commutator on the armature. One difference is that the trimmer motor has a fan on it and it's open construction with air intake on the top and warm air exhaust out the bottom around the top of the spool.

Had a 110 v that I converted to 48 volt NiCad because the rectifier
burnt out quite powerful 16 inch dia. swath ....about 3/16 trimmer
cord ....when you needed more cord just unwinded one turn.
48 volts was adequate.....
BTW Wearing open toed sandals and shorts not recommended,
goofy co-worker told me one time, as he related his experience with
his new weed wacker "next time I'll wear shoes and long pants", he said. ::)
