Batteries: Which Lithium Chemistry and How Are You Charging?

[Bunky.F.Knuckle]

I have used anything from truck cap foam to foam rubber to velcro. It all work to isolate some vibration.

I contacted Pulse regarding the confusion about the discharge rate on their 2,550 mAh 2S lipo RX pack. One place it said 6C another said 15C. Their answer is that it is 15C, meaning that the pack is rated for a 38 amp continuous load. Most lipo can handle spikes of twice their nominal C rating, meaning spikes of 76 amps will not be an issue. With dual packs we are talking about 76 amps as the nominal full continuous load rating with spikes of 152 amps not being an issue.

I had to get some heli parts and Helidirect was offering 10% off for 4th of July so I have 3 Pulse 2550 packs coming.

I am already using this same pack for my receiver on my 700 heli.

Figured I'd mention our LiPo tutorial thread since the discussion might generate some questions
