YOUR_DJ Posted January 9, 2022 Share Posted January 9, 2022 (edited) My Arrma Granite BLX stops driving after a few seconds, I am even driving slowly. I am 15 so I don't know what to do, I am worried about taking it apart without knowing what is going on. I don't want to have to spend $100 to buy another ESC. By the way the truck is years old, and the batteries are brand new with an new lipo battery charger, I asked my uncle what could be wrong with it and he says that he doesn't know. I also have been driving the truck rear wheel drive, because I broke the front differentials racing against a Senton, the front diffs are out and not causing a problem. The truck has had problems before, I also have a new brushless motor, and a new servo. The truck just one day stopped driving for more than a few seconds, and has been in storage for months now and I am trying to get it back on the road, at least two wheel drive. I hope this is enough to help you guys get the truck back on the road. Edited January 9, 2022 by YOUR_DJ Quote Link to comment Share on other sites More sharing options...
YOUR_DJ Posted January 9, 2022 Author Share Posted January 9, 2022 So I just plugged my old battery into the truck and it is working perfectly, the problem is the battery doesn't have the info on it. Quote Link to comment Share on other sites More sharing options...
stretch Posted January 10, 2022 Share Posted January 10, 2022 Do you have a pic of both the batteries? Quote Link to comment Share on other sites More sharing options...
Tug Posted January 10, 2022 Share Posted January 10, 2022 Are both batteries lipo? Quote Link to comment Share on other sites More sharing options...
YOUR_DJ Posted January 10, 2022 Author Share Posted January 10, 2022 They are both lipo, but I found out that my truck is picky about the batteries it is using, the battery it won't work with is a Hoovo 11.1v 80c 5200mAh lipo, I found it on amazon. I don't know what brand the other battery is, the branding plastic is gone. Quote Link to comment Share on other sites More sharing options...
YOUR_DJ Posted January 10, 2022 Author Share Posted January 10, 2022 The battery that doesn't work with the truck is this one: https://www.amazon.com/HOOVO-Battery-5200mAh-Connector-Airplane/dp/B08V8Y7Z3Q/ref=sr_1_6?keywords=hoovo%2B3s%2Blipo&qid=1641855730&s=toys-and-games&sprefix=hoovo%2Ctoys-and-games%2C345&sr=1-6&th=1 Quote Link to comment Share on other sites More sharing options...

YOUR_DJ Posted January 11, 2022 Author Share Posted January 11, 2022 So my problem is pretty much solved, I got a budget battery, and I got a bad quality battery, at least I know that I don't need to buy a new ESC. Thank you!! Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted January 11, 2022 Share Posted January 11, 2022 Umm how were you charging the batteries/how do you charge your unknown battery? Quote Link to comment Share on other sites More sharing options...

Ross9999992 Posted January 11, 2022 Share Posted January 11, 2022 Yeah but there are many many different lipo chargers…what’s right for one is not always right for another. Maybe your new lipo wasn’t bad, maybe it just wasn’t charged for instance. How did you figure out it was bad? Quote Link to comment Share on other sites More sharing options...
stretch Posted January 11, 2022 Share Posted January 11, 2022 Are you balance charging them? are the cell voltages very close together? Quote Link to comment Share on other sites More sharing options...

But I have just charged the battery which I thought was bad, and now it is running fine in the truck. I guess that I didn't charge the battery enough. It seems to be working fine now.

You could consider a charger upgrade but I understand at 15 money may be a problem…I’m old(ish) and money still is a problem 😂 I’m unsure how much you know about lipo care but you could consider getting some kind of “lipo checker” if you don’t have one so you can check the voltages of each cell. You also shouldn’t store lipos charged up just as a little fyi. If you haven’t I would definitely recommend reading at least the lipo guide available on here and maybe even do some googling on lipo care…they are great but should be looked after 👍🏻 Quote Link to comment Share on other sites More sharing options...

Suits Posted January 17, 2022 Share Posted January 17, 2022 Hey man, might be worth picking up one of these, its a battery checker/tester. Really helpful for quickly checking the capacity level of your batteries and the individual cell voltages of them. Only £10 and really, really useful. https://www.amazon.co.uk/Digital-Battery-Capacity-Voltage-Controller/dp/B07QB6D2Z5/ref=sxin_13_pa_sp_search_thematic_sspa?crid=1KS2PGCRG3WLE&cv_ct_cx=lipo+battery+tester&keywords=lipo+battery+tester&pd_rd_i=B07QB6D2Z5&pd_rd_r=a0ce78ad-3575-47da-a0dd-843e91634d3c&pd_rd_w=TEIVx&pd_rd_wg=P3Ms8&pf_rd_p=7468d229-fb8e-4951-8ff4-df03d0bdb454&pf_rd_r=47XARZJR7CHNS4HRAKDQ&qid=1642425977&sprefix=lipo+battery+tester%2Caps%2C69&sr=1-1-b75715df-0cbd-4312-a971-de5362256967-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyR1RLVVpZOE1FQ01VJmVuY3J5cHRlZElkPUExMDQyMzc2MU9MNzFVREJUUDVVUyZlbmNyeXB0ZWRBZElkPUEwNDMzNTEzMUI1SU43SDVSQUpFSiZ3aWRnZXROYW1lPXNwX3NlYXJjaF90aGVtYXRpYyZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= Quote Link to comment Share on other sites More sharing options...

YOUR_DJ Posted January 18, 2022 Author Share Posted January 18, 2022 Well, I am American, so I use dollars. I just prefer the british because they just get to the point faster than us americans. If that offends anyone I am sorry, but it is true. I will definitely buy one of those. Thank you. 1 Quote Link to comment Share on other sites More sharing options...
