Anyone use kinexsis lipo batteries? Are they any good?
Never heard of them. I have been using Turnigy and Rvolectrix graphene 3S packs over the last season with good results. You want a pack with a high C rating and the Kinexsis you mentioned seemed to only be 30C. 50+ is preferred for faster electric boat applications.
I would be using these on my stock stealthwake. If I like them I'll get the larger c rated batteries for my next boat.
IMO, wasted money. Why not spend only a little extra now, and then you have a larger cache of batteries that can be used in any of your boats later on? An alternative theory anyways, and not my money to spend.Quote:

Where do you get your turnigy batteries from?
Hobbyking. I get the Revo's from OSE.
Can you get revo batteries on here with the ec5 connector?
They come with bare leads. Solder on whatever connector you like.Quote:

That's what I did last night. I hope it's 5 days. My Miss Geico 29 should come in next weekQuote:

I'm hoping so, mine hasn't shipped yet.
Took your advice and ordered a pair the other day, thanks. Quick question though pls. For 10.00 more than I usually buy, the 5000Mah 420 3s, I bought a pair of 435's, assuming I can charge them to that number. Preliminary investigation into my owners manual indicated my charger will only charge up to 4.20v ( Ultra Power UP200AC DUO ) so what am I to do? Do any of you guys know if there is a work around to charge these up to the 4.35v, or am I stuck charging a 4.35v to only 4.20v, which probably isn't good for the battery at worse, and at best I pissed away an additional 10.00 per battery that I can't get the most out of. ThanksQuote:

However, the rated capacity in mAh is based on a 4.35V charge, so if you charge to 4.2V, the packs will output less than 5000mAh. How much less, I don't know off the top of my head.
IMO, you spent $20 you didn't need to and got batteries that weren't the best match for your needs.
Clearly in retrospect, yes. I figured with eventual upgrades to esc and motor these would be beneficial, however the chargers ability to charge them didnt occur to me until later. Perhaps I can trade them even up for a set of new 420's? I bought them with no connector terminals. They should arrive next week.Quote:

The 4.35 packs in my opinion are a safer more stable blend with headroom. Most of my packs are the hv blends and compared to my 4.20 packs stay cooler and seem to hold strong a little longer.
Take note.
If you do change the voltage setting to 4.35V/cell, make sure you don't charge any standard 4.2V/cell packs on that setting.
The problem I had with that charger is the batt profile saving. You can for example set it to remember to charge to 4.35/5800 mah. It will remember the 4.35v part (4.27 for mine) but (mine anyways) I would have to change the mah setting every time. Got annoying quick especially with multiple packs with different ratings. I had enough and saved up for the PL8 with the parallel x6 board. Will never look back!!
Thanks Erroneous and 785. I was considering saving the profile to distinguish between the 420's and 435's. I see it can manually be upped to 4.30v. Sorry to OP as well for the thread jack. Thanks guys.
Check all the settings EVERY TIME! Its a great charger but make sure its set up before charging.
Thanks. Navigating around the programs is taking me a little time as Im entirely new to this hobby and tech. User manual is mediocre at best.
