You drove it down to 8v total? You shouldn't ever discharge a lipo below 3.0v per cell (9v total on a 3s) under load. The resting voltage shouldn't be under 3.7v per cell.
Fully charged a lipo pack has 4.2v per cell, so your 3s should've been at 12.6v to start with. 3.8v per cell is almost dead to begin with. Did you charge the pack before using it? Are you using the balance charge mode, or fast charge? Try balancing it to see if it will detect it as a 3s pack. With the balance tap plugged in, it *should* know that there is in fact 3 cells. If not, you have to VERY carefully charge it as a nimh pack for a short time to bring the voltage up above 9v. Do that as a last resort though, and make sure you're sitting with the pack and take it off as soon as it gets above 9v. Even if you do manage to revive the pack, it will likely have done some damage to it and might not last as long in the long run. I thought you had a LVA, wasn't it going crazy with the pack discharged to that point? |

R indicates cell count recognised by the charger S indicates cell count selected by the user. As for the lipo, well I'd maybe ditch or be very careful of it now I'd set the alarm at 3.5V per cell if it's not set at that reading manuals is good |

Battery started to show as 3s again...charges fine etc..I put it on storage mode since I have to order/pick up a working lipo alarm....really hope I didn't do serious damage to the battery. |

what was the voltage of the individual cells.
If your experienced with lipo, i'd say, see and check what it's like. If your not experienced and ran it without charging it first, then maybe you should ditch it and read up then buy some new lipos. |

My younger sister crashed it into a side walk dead on the car was too fast...the chassis broke in the front...after fixing it by attaching a metal plate on the bottom its not a 4wd anymore....next day i crashed it into a commercial garbage tank and broke it again....this time the chassi is not fixable...I thought i blew out the ESC as well but actually the battery was just poorly connected. Everything works and in good condition except the chassis. Anybody here can help me find a chassis for this? I've searched almost everywhere and having a very hard time finding one... If i can find a chassis I will probably upgrade to brushless system with a 2s lipo...3s is too much to handle (should have listened to yo u all) lol. If I cant find one i'll probably going to part it out or sell the whole thing you needs extra parts...most of the parts are intact and perfectly fine...the chassis is the main thing damaged. |

A455 HPI Chassis. I think that's the chassis.

i seen them on amazon. I don't know how much different the nitro version is maybe that can be used with the help of a dremmel.

The nitro one looks a lot different, the electric one is a molded tub.
If the wheelbase is the same on both, and the bulkheads are the same on both then you could drill new holes where needed in the nitro chassis (assuming you don't need a hole in the middle of the cutouts for the engine) to attach the electric specific parts. |

thats the same pic i seen just different seller.
the plastic ones do seem very rare/ non existent. If parts break again you may struggle to find anything. You could contact HPI maybe the parts off this might fit on a different chassis with only a few parts needed to complete it. Like my maxx, if that chassis breaks i'd have to buy the newer version with chassis braces and transmission, the front and rear will bolt straight on |

the chassis is broke and the front left axle broke right where the steering dog bone connects to the axle on the driver side. Everything else is intact and perfectly functional. I'll give someone a very nice deal on the whole thing. But if you need parts thats fine too. i dont have nay trader rep here but i can make ebay listings.... ebay ID: pinkraza786 100% feedback |
