andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 car is probbebly a few years old but was a display model and battery was still sealed in originel bag so this is also at least a couple of years old no way of knowing how old second battery is what should i do tuesday when i go back to shop to pick the batteries back up the charger is fine as it chargers the 5ive t batteries fine Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted August 30, 2015 Share Posted August 30, 2015 It does sound battery related... But could it be the receiver? Spektrum are relatively known for crap signal with certain receivers on large scales, typically it just cuts the engine but a complete loss of signal could do the steering and throttle too. Worth exploring a different radio just to check it? Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 both batteries were charged again before i ran it and in shop showed 6.4 vlts and 5.9 vlts but he said they were flat and when hhe went to dicharge one he said he couldnt get anything out so he would cycle both for me on his all singing danceing charger 1 Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 he checked reciever in shop about 60 to 70 yards and all seemed well Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 by the way you were spot on diagnosing my nasty noise on my 5ive t it was the spur gear Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted August 30, 2015 Share Posted August 30, 2015 Me?... And it might not be 'active' when the engine isn't running. It's a weird interference issue with the aerial and the coil.. Apparently. So it'd be worth actually just running the truck on something on the ground so the wheels aren't touching and then walk away from it without using the throttle or steering at all... See if it still does the same thing when it's not under any kind of voltage load. Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 this is what he did in shop he held model of the bench with engine running and the assistant walked to the other end of shop and all worked well and yes i think it was you that sergested spur gear on my 5ive t but it was a while ago and ive only just had chance to get it sorted as my wife has been very ill it was last may i think Quote Link to comment Share on other sites More sharing options...

andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 the battery box on th dbxl is really small so would have to leave the 3300 s loose in the car dont like the sound of that Quote Link to comment Share on other sites More sharing options...
Rover Man Posted August 30, 2015 Share Posted August 30, 2015 It will fit if you leave the lid off. Just tape it for a quick test run is all. Quote Link to comment Share on other sites More sharing options...

andy and dan Posted August 30, 2015 Author Share Posted August 30, 2015 does any body know whats the largest capasity battery that fits in the standerd dbxl battery box Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted August 31, 2015 Share Posted August 31, 2015 Yes. Killer RC lipo with larger lid. On a budget, (like me) nanotech 3000mah lipo.I'd suggest a read through the Dbxl thread, it's all in there with prices & links. 1 Quote Link to comment Share on other sites More sharing options...
.AJ. Posted August 31, 2015 Share Posted August 31, 2015 Chuck the stock RX battery in the bin like every other DBXL owner! It's junk Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted August 31, 2015 Share Posted August 31, 2015 (edited) Here it is, largest battery for stock lid: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=34387 It's lipo though, is that a problem? AJ is right, no owners ever use that stock pack, I never used mine once. Edited August 31, 2015 by Bigjimknickers Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 31, 2015 Author Share Posted August 31, 2015 My charger does lipo but I've never used lipo before are they any different other than name Quote Link to comment Share on other sites More sharing options...
andy and dan Posted August 31, 2015 Author Share Posted August 31, 2015 So much for trying the 3300 out of my 5ive_t in the dbxl before i go to work its another British bank holiday wash out Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted August 31, 2015 Share Posted August 31, 2015 Main difference are you need LiPo compatible servos, or at least the voltage anyway. You also need to keep them at storage voltage so if a day is cut short, you'll have to discharge the pack down. IMO a LiFe pack is a good alternative as well... Some are even smaller than LiPos and don't require any storage mode or anything. I ran one in my Shorty, it was only an 1,800 and it lasted well. When I was looking into them a few lads said they'd got 5 tanks of fuel from one 1,800 and it still had juice left, although you could always go for something like a 3,000 or even bigger to be on the safe side if you ever plan to go all day Quote Link to comment Share on other sites More sharing options...

Noj Posted August 31, 2015 Share Posted August 31, 2015 An, they've moved from Halton then... I know many members rate them, I don't in terms of technical ability....as in, my impression is that they don't always know what they're doing with electrics... Hope you get it sorted anyway Quote Link to comment Share on other sites More sharing options...
