I'm new to the forum, new to this hobby, and got a new stampede 4x4 that came with a traxxas 2s 4000mah lipo. I also bought a charger which is the thunder ac680 because the charger that came with it was too slow to charge. I ran it about 10 times since I got it.
1. the lvc cutoff stops at 3.2v and the other cell is at 3.4v. Is this normal? Also when I'm done charging, it's showing that one cell has 4.20v and the other 4.19. Is this normal?
2.after charging the battery, it's showing that 3910mah has been put back out of 4000mah.
Is that bad that I used more than 90% of the battery or is this normal? I thought when the lvc cuts off, it means that I used about 80% of it? I charge the battery at 1c(4amps) takes about an hour or so.
3. When I push down on the car, there's a squeak noise coming from the halfshaft( I think that's what it's Called). Any ideas what the sound is and how to fix it?
4. I want to upgrade to a 3s battery but I've been told that a lot of parts will break. What should I consider getting before upgrading to a 3s to handle the power?
I know that this is a lot of question but please help a newbie out . Any help would be greatly appreciated thanks
