Seminole81 Posted April 4, 2021 Share Posted April 4, 2021 (edited) Trying to charge. How long does first charge normally take? Been on about a hour now…battery isn’t warm or anything (guessing that’s good?) took about a hour and a half, green light on now.

walkbythesea Posted April 19, 2021 Share Posted April 19, 2021 (edited) Just a couple of questions I couldn’t see answers for when I scanned through... 1) If you charge your lipo but life or weather gets in the way of your trip out but you intend to go out soon instead, how many days would you keep it in a fully charged state before sticking it down to storage voltage? 2) New battery with higher capacity arrived and I ran it today, but didn’t get anything like the run time I expected - old and new compared in the picture below, along with stock 2950kv motor and stock ESC - the old 3250mah battery seemed to last longer, but performance better with new battery - is it simply that at 80c the new battery can let the amps out 4 times faster??

Stormbringer Posted April 19, 2021 Share Posted April 19, 2021 it can take a few charge discharge cycles for to reach its peak 1 Quote Link to comment Share on other sites More sharing options...
suicideneil Posted April 20, 2021 Share Posted April 20, 2021 1) depends how brave you're feeling, I wouldn't leave it more than 2-3 days at most though. 2) As stated, conventional wisdom is to do a few 'gentle' discharge cycles to break-in the lipo before canning it. Bare in mind though not every brand labels their lipos accurately ( cough Maxamps cough ), so... yeah. 1 Quote Link to comment Share on other sites More sharing options...

Seminole81 Posted April 20, 2021 Share Posted April 20, 2021 What’s classed as “damage” to a hard case LiPo? After a few runs, I’ve had scratches etc. but also noticed this on one? It’s been strapped in fine etc. it’s not raised up or indented either? Just somewhat deformed? Quote Link to comment Share on other sites More sharing options...
walkbythesea Posted June 10, 2021 Share Posted June 10, 2021 mah + c vs runtime comparisons…? So I basically have three different rated types of batteries, all 2s 3250mah 20c voltz 5200mah 80c zeee 6200mah 60c zeee Using my 2950kv brushless Outlaw as my test bed flat out over the same offroad course each time. The 3250 gives me 10 minutes The 5200 about the same but with very noticeable much improved punch and acceleration The 6200 gives 12 minutes The 3250 gets hottest under discharge Does this sound about right??? I had hoped for a much more improved runtime with the higher mah batteries, but I guess the more easily available amps with the combined improved c rating is offsetting runtime against punch and acceleration? Is that correct? Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted June 10, 2021 Share Posted June 10, 2021 That sounds right to me anyway mate the 3250 isnt able to supply the demand of the esc/motor but the higher c rated batteries can hence increase in performance 1 Quote Link to comment Share on other sites More sharing options...

Seminole81 Posted June 21, 2021 Share Posted June 21, 2021 Anyone have an experience with "Goldbat" LiPos? Seen some in the Prime Day sales, 5200 3S LiPo for £19...bit dubious on it. Quote Link to comment Share on other sites More sharing options...

Allan k Posted July 7, 2021 Share Posted July 7, 2021 ‘Im new to lipo batteries.. I will need a one or more for my losi lmt when it arrives eventually… I decided to go for 2s, but some are high are voltage 7,6volt and not 7,4 what to choose and why?

Personally I’d probably just go with the standard LiPo as I would expect these to be a bit cheaper and I doubt I’d be able to tell the difference (all else being equal with their rated capacity and discharge rate) just by taking a truck out for a play.

Okay, I had the same thoughts. But what is the difference inside the battery? I thought all lipos were 3,7volt Quote Link to comment Share on other sites More sharing options...

I would expect these changes to be fairly subtle and I doubt it would be possible to distinguish between the two just by looking at a battery pack (ignoring the fact that they would probably have stickers on pointing out their differences) Quote Link to comment Share on other sites More sharing options...

Lipo cell is 4.2 volt when fully charged and around 3.7 , 3.8 when storage charge. When they go below 3.2 volt they getting electrolyte degradation and below 3.0 v irreversible damage. 2s lipo means 2 cell so fully charge 2s is 8.4 actually. All my 2s lipos have 7.4 on a label so 3.7 x2. I always go for higher C rating that my ESC ask for to be on a safe side. Quote Link to comment Share on other sites More sharing options...

Zash Posted July 31, 2021 Share Posted July 31, 2021 Remember gentlemen, ALL manufacturers lie about their C ratings. Here are TESTED C ratings as of June 2021. Note how no manufacturer actually goes past 45C: Quote Link to comment Share on other sites More sharing options...
Buggy Malone Posted November 25, 2021 Share Posted November 25, 2021 Hi All I picked up a FTX Outlaw buggy last week and it came with a Voltz 2S 3250mah 20C battery. I would like to buy one or two more Lipos but after delving through the Modelworld web shop I'm now confused as to what battery manufacturer is best. I have a choice of the following brands so what would you guys recommend - or are they much the same in terms of performance and quality? Voltz Corally Overlander HPI Plazma Many thanks, Andrew Quote Link to comment Share on other sites More sharing options...

Redback Posted November 26, 2021 Share Posted November 26, 2021 I've always had good results with. Gens Ace Turnigy Intellect The Voltz that comes with the outlaw brushless is decent, had mine a good few years and still holds its charge. I would avoid these tho, they come bloated and dont balance, the leads also snap as the outputs are so tight, decent paperweights but nothing more.
