richardr33 Posted September 20, 2021 Share Posted September 20, 2021 Hi guys, my boys have been on at me to get the rc cars out, so I've bought some new battery's and here we go, x2 out the 3 work, the 1 that doesn't work, it steers and goes forwards and backwards for about 15 seconds then doesn't go, it always steers but doesn't go forwards and backwards, any ideas, it's been a couple of years. 👍🏼 Quote Link to comment Share on other sites More sharing options...

Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 (edited) Just checking that’s a 4s lipo and it’s charged above the lvc? Also does it have full power or “low” power for those few seconds it works? The pic is taken from a random quicrun manual and suggests it’s lvc kicking in 🤷♂️ Edited October 14, 2021 by Ross9999992 Quote Link to comment Share on other sites More sharing options...
richardr33 Posted September 20, 2021 Author Share Posted September 20, 2021 (edited) It's a 3s battery, it's been weird , I put a 2s on it and it went low power Edited September 20, 2021 by richardr33 Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 The video it beeped 4 times I think…that means it thinks it’s running a 4s and is doing the lvc check based on that. Fully charged 3s (12.6v) is still still below most 4s lvc options…set that to auto cell count or manually set the 3s and try again imo 🙂 Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 Yeah 4 beeps…that’ll be the problem 👍🏻👍🏻 1 Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 Fyi odd numbered cell counts can make that happen on many esc’s. Be wary every time you switch on or manually set it to 3s (the better option imho). Quote Link to comment Share on other sites More sharing options...
richardr33 Posted September 20, 2021 Author Share Posted September 20, 2021 I've set the esc with a hobby king program esc to auto on the cell for the lipo, the guy I bought them off said they where 3s, I used both of them on my Hobao that can run 6s x2 3s and it was fine, if they where 4s it would have blown up meaning 8s 😂 Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 (edited) Yeah that auto setting is the problem…they prefer to choose even cell counts…just manually set it to 3s and it should be all good I’d say 🙂 Ofc then you have to make sure to only use it with 3s for the lvc to function correctly. The sticker on the battery says 3s right? 😃 Edited September 20, 2021 by Ross9999992 The last bits Quote Link to comment Share on other sites More sharing options...

Ross9999992 Posted September 20, 2021 Share Posted September 20, 2021 Yeah so just set the esc to 3s and that should solve the problem.
