Heya, in the next month or so I'm replacing the 12v on-off motor of a small helicopter tug (used for towing lightweight aircraft around the hanger) with a 24v variable throttle system. This is for a family friend. Right now it's running off of a 20ah 12v SLA, and can't easily fit another 12v SLA. Plus, the old battery is dying. So rather than replace it with two smaller 12v SLAs, I thought I would throw out a line here to see if anyone has a LiMn pack or a small 24v LiPO4 pack to sell. Just needs to be capable of 20amp bursts & 10amp continuous. Even that continuous would almost never need to be more than 6 minutes.
This is not a super high priority, but if anyone has one for sale please let me know the stats and what you wanted to get for it.
