MaxAmps Race Edition Lipos

[fastbaja5b]

I'm sure the highest paid department at Maxamps is marketing, when you spend enough on advertising you can make people believe anything, how many magazines regularly have maxamps as "Battery vendor of the year" etc. The sad truth is, 95% of people who buy Lipos believe the hype and not the data, and are just backyard bashers who don't go too deep into it and have never looked at an rc forum.

I mean, people believed VHS was better than Beta didn't they?

Guys, I found the missing graph!


Amazing!

Someone needs to find jayjay's original green girl/sun graph lol..

For that matter someone needs to find him, wonder if the wife killed him?

Found it!

More accurate than ever.

Good to see everyone having a laugh about things. Nothing is worth busting an artery over. I wish someone from maxamps would have popped in a little bit more often and had something new to share. I still don't see where this "True 150C" can even come close to what these new Race Ready LoPos can do in an R/C vehicle or anywhere else for that matter. Just because a charged cell can take a milisecond hit up near that range in no way gives anyone the right to claim that as a 150C battery. That is a joke. Unless like you stated the test was done douced in orange juice, which gives the cells incredible citrus superpower. ha ha ha ha. You guys are a hoot.

Whats the point of advertising a battery as being waterproof if they damn well know the whole thing cant be submerged because the connectors will short out, regardless of how much silicon they slap allover the actual cells? Its a pointless feature to try and advertise, just like the 150C/ 75C rating since the wires will never support that much current draw.

RCCA will never publish ( truthful ) lipo comparison results, nor will any other MA sponsored magazine or website- it's bad for business if MA packs are shown to not perform as well as they are advertised to. Common sense there.

Just like has been said a hundred times before, there needs to be some form of independent body ( like ROAR, only better ) that sets the standards for testing and rating of lipos and how that info should be displayed on the pack to let users make an informed choice; you could have a rep from all the major lipo companies give there input as to what constitutes the continuous and burst C ratings ( X voltage under Y load @ Z temp for ?? seconds ) in order that all companies adhere to the same rating system. Very simple concept, unlikely to ever happen. Until then word of mouth and user feedback will continue to determine which brands are good and which arent/ are overpriced; that may mean taking a leap fo faith sometimes to try something new, but its how the hobby, how any hobby has always been...

Honestly when it comes to this I wouldn't mind ROAR stepping in. At the very least, any ROAR approved pack should be rated with the same standards. Roar can decide what load, voltage etc. As long as all packs where rated the same way it would be a major acomplishment. Maybe the rest of the batteries would wind up being rated the same even if they weren't ROAR approved. I don't care for ROAR but they do have the necessary pull to acomplish this. Plain and simple if your battery is going to be ROAR approved the C rating has to be factual and they test it themselves to make sure it meets the C rating by the guidelines they establish.

Next up, can we have ONE kind of balance tap? PLEASE!!!

The connectors do not need to be water proof since electricity follows the path of least resistence. you could strip the insulation off the wires , put the "waterproof" pack and leads in water, hook a brushed motor up to the pack and put that in the water as well and it would work like normal, provided the + and - wires were not touching eachother or the motor can.

True, but try that in salt water..

It wont do the esc any good being submerged- doesnt matter how waterproof the batts are if the rest of the electronics wont normally survive a good dunking; more luck than good design if they do..

I tend to lean towards Neil on this one.

Water and electricity don't mix well because of the conductivity of the water. Water by itself (distilled water) does not conduct electricity.

It is the Mineral content of the water that makes it conductive. Heavy metals and minerals in the water allow the electrons a path of flow.

DC current flow through water equals electrolysis. This will occur at any connection that isn't completely waterproof.

[josh9mille]

I dont really think that is an issue for RC vehicles lol. I have never saw or heard of anyone complain about their deans or trx connectors shorting out because of water. Have you?

[suicideneil]

Not many people have driven their r/cs into the sea- mainly freshwater streams or lakes its mainly the esc that croaks if anything. Corroded terminals aint much fun though, but it all comes down the likely hood of someone needing waterproof electronics enough that they will happily pay over the odds for a bit of silicon to be slapped on the pack. How many of us intentionally drive though water- cant be that many..

[Bondonutz]

Fine idea but ROAR doesn't give a shizz about C-rateings, safety and playing fair is whats most important. MA packs fit the critera since they just puff not explode.
