MMM 2200 on 6S with 3905 Emaxx and zippy 5000mah 20C cells

I think you see some zippy bashing because people who sell the lipos that cost three times more are concerned they cant compete. I have run them now in the e-revo, emaxx 3905 and slash and see no real performance issues vs Neuenergy and maxamps in real world racing and bashing. The neuenergy's are the ones that get pretty warm where the zippys and newer maxamps dont. the neuenergys wires were cut from the case opening where they come through - ie no reinforcement, the cases open - have to seal them shut etc.
I am not that impressed. they may hold their voltage longer but in real world ie - not trying to break speed records in front of your house the zippys seem to be no better or worse than other batteries i am using and we push the models pretty hard.
the reality is that if you misuse lipos- dont use LVC's and or let them discharge they are going to fail. if you charge them at the right C and keep them balanced the zippys are just fine for most use cases

i ordered some Zippies a month ago on backorder, puffed an older maxamp cell and emailed the company to ask when the Zippy batteries will be shipping out.... They told me July... so they look like a great value, but I have to wait 3 months to get said value. Lucky for Mike his C-Tech batteries seem to be well liked, $300 later.... I will be checking out Mikes batteries while waiting for my value batteries.

Sorry for the rant, I know it is sorta off topic, I guess I just want to warn anyone interested in a Zippy (from hobbycity/hobbyking) to not order a battery not currently in stock.
