Lemme guess the 245 is double and I guess I don't need motor break in my whole fleet is all brushless soon to be lipo

120 w/ free ship on ebay...Cant go wrong for a double lipo charger and all duratrax has 5 year warranty! Had 4 of their chargers and no problems yet...bro in law had dynamite and had issues but all Duratrax have been great

Very very tempted by the 245 but I just saw the EZ peak plus and that has very good reviews can charge 2 LIPOS at once has a screen a balancer and is 99 dollars street price plus my Lhs carries it choosing a charger is Harder than choosing my first car! LOL what's a good discharge rate aka C rating running hobbypartz leopards brushless 4750 kv combo and a traxxas 1/16 brushless system Thanks for all the help!

The EZ Peak lets you charge two batteries via parallel charging. You can do that with the Duratrax 235 as well... if you did it with the 245 you could charge four batteries at once. :lol: The EZ peak does do storage charge automatically, but you could do it manually with a simple egg timer to remind you to check voltage levels. I would bet that the Duratrax gains the functionality soon... it can be updated via USB. The EZ peak must be new... it looks decent, don't know anything about it... Still have my 235 for cheap... if you change your mind just let me know. :p

As far as discharge rate for the battery... not sure. You can ask the guys in the electronics forum about it, and ask for their choice for cheap charger as well. You will get more replies there. I would bet you get a lot of votes for Duratrax... and remember, if you are charging multi-cell Lipo, a balancer is pretty much required. So if the charger does not have it built in, its an extra $20 to the cost.

This was suggested by another member it has a screen but no deans connectors any good?

These Bantam B6 knockoff chargers will get the job done. I sell these chargers and I've only had one bad one out of the last 50 I've sold. Buy one and save some money. Most all chargers are made in China anyway.

I've actually heard that nitro rcx has very good customer service don't know if it's true or not I'm thinking about the 2nd one I posted how much is the thing that attaches to it and what is it an inverter? Thanks for the help

marine6680 06-05-2012 03:33 PM

Inverters change DC voltage into AC voltage.

I am about to install one in an aircraft tomorrow. :p

An rc or a full size?

Lol, I would assume 1:1. There's no need for AC voltage on an RC vehicle.

LOL I know nothing about electricity also what happens if you get hot solder on carbon fiber thinking of getting a kit with CF chassis should I solder outside it?

To be safe yes... The carbon fiber is held together with epoxy resins. They all break down under high heat, some are better than others. Its really up to you though. An occasional drip of hot solder would probably not hurt a quality carbon fiber piece, but any cheaper or poor quality stuff may use cheaper resin and more easily damaged by heat.

Carbon fiber also breaks down in UV light... but I doubt that is of concern to the lifespan of a RC vehicle... but it is for full size aircraft. Carbon fiber parts for aircraft must be painted and never exposed to sunlight.

This I assume is why people keep thief Zonda's and other naked CF cars locked up in garages Thanks for all the help sorry for taking over your soldering thread LOL

Its all good.

I got a bad nanotech 2 cells lipo and I open it up to find out one of the tab was loose. I try to solder it together but it won't take any solder. I use flux and sand down the tab but still can't get 1 drop solder on. I use hakko 936 with wide tip and hottest setting. The tab is kind of like soft aluminum. Am i using wrong solder(60/40) ? Halt to waste a battery because loose connection and seem it is fixable. So what's your suggestion ? Thanks
