so my 3s smc graphene extreme v2 battery has seemed to become harder and harder to charge. Now if the battery was 1 to 2 years old then I would round it up to age. Fine whatever. I know a battery will not last forever. However I got this battery in June of 2021. it is a 3 month old battery. Already the cells seem to have a hard time balancing when charging. Like here is a example of what I mean from are last camping trip. I charge the battery and the two cells will get to 4.2 but one lagging behind. The battery has already hit 5200mah so the thing is charging at like .2amps. So that charge took 85 dang minutes. a step up from the usually 55 -> 60. The little research I did do could be linked to a difference in IR [ i cant measure this] or in some cases a bad charger. I would like to think my charge is good but I am no expert. I have a HTRC c150. I am in the process of doing a storage charge and well this is how the cells ended in voltage. 3.805 3.803 3.810 ( this is what my charger is telling me ). The thing however is I think it is the charger and the reason is everything that things starts to charge a battery, it makes a horrible sound every single time. Along with it people 2-3 years old vs a 3-4 month old battery. On the other hand however my 2s smc true spec which happens to be the same age of the charger has never ran into these issues. So that would lead me to a bad battery. All I am wanting to know if you can answer it is what is the problem here. charger or battery.
*both batteries are 5200mah
*another note is the 3s battery will fill up in mah before the cells even get the chance to fully balance where I swear the 2s never did. They both are the same brand but I just don't understand what is happening. I went cheap on the first one it lasted the time I needed it to. I go and get one a lot of people said was good and speed runners liked the brand ( I think) and where using it so I was thinking it was a good battery. I would like to still believe that the brand is good but in this case with my experience then cheaper is better

Lipos are one of those hit or miss type of things. One guy will love them, another will hate them. I try them all and see what works. Some don’t have deep pockets and can save a few bucks buying less expensive packs.
