MaxAmps Race Edition Lipos

[padrino]

Using the way they market as insight into how ethical they are I expect the cell manufacturer probably doesn't even rate them as 75C (note MaxAmps points out it's the cell rating, not the pack rating) however MaxAmps is assuming something to allow them to take some of the liberties they do.

No one will draw 75C continuous for any period of time from a cell or the pack, they sell to the RC community so from their point of view it's reasonable to assume that as fact.

Who knows because not one LiPo cell I've seen, granted not tons, has ever been marked the way NiCd and NiMh are with the exact specifications of the cell.

Hey guys I think I have found a cheap way to test lipos and how much current they can really hold. I just tried a Diesel Glow Plug from a friends Toyota truck on my Turnigy 4S 5K 40C. With my clamp meter I saw just over 15A of current. I left it on for about 5min and other than the Glow Plug getting stupidly hot everything else was cool. I should have measured the voltage too but couldn't find my Fluke meter.

Now I know some might be saying "What's your point?" but this could be easy way to test what sort of currents lipos can handle. Just add a few more Glow Plugs in either series or parallel (not an expert on this) and then just see how the batts hold up temp wise and if they puff at all. A clamp type current meter would tell you exactly what sort of amps you are pulling and a simple IR temp gauge will tell you how stressed the cells get. Oh and also a visit to a wrecking yard to pick up some Diesel Glow Plugs. Maybe from a big truck they will be bigger and you would need less of them. What do you guys think? Possible?
