As has been already pointed out by the_rc_guy, you really need to watch more closely for what people say: "A" is not the same as "C" or "S". Neither in letter nor in meaning. 2C for a 5200mAh battery is 10.4A not 2A. And those two are not really close, are they?
Ok, next issue: 50C isn't even close to "the best" battery, and hasn't been for years, but my guess is, it was cheap. However, while not being great, it is good enough for most hobby users / bashers - so just don't expect any wonders from it, and to play it safe, I would stick to 1C. i.e. 5.2A for max. charging amperage. Less than that makes no sense IMO.

Also a good quality charger is key to get the best out of your LiPo batteries, both in performance and also battery life. Yours, not even having a storage mode, sounds like you were pointed to something more cheap than good as well, just as with your batteries. Also I personally would not keep batteries sitting fully charged for a whole day, let alone two. I might occasionally charge mine perhaps an hour or two before, but normally only right before use. Same goes for storage: usually I do it before I leave the track for the day or more or less immediately after I get home, same evening at the very latest.
Not trying to scare you, but skimping on both batteries and charger coupled with not really understanding how any of this stuff works (or which letter means what) is a recipe for (possible) disaster. Luckily it happens rarely, but it still does happen, that LiPos that are being treated wrongly go up in flames quite spectacularly, and there's been cases where they took the whole garage or even house with them in the flames. Again no reason to panic, but make sure to use at least decent equipment (no need for top of the line stuff unless you are in high level racing) and most important of all: make sure you learn the basics (about letters like S, C, A, V, mAh) and how this stuff works and what to watch out for.

The 50c battery wasn't really that cheap, it was around $85 which if I'm not mistaken 100c Lipo batteries are around 90-100 dollars for a decent brand.
I am aware of the risk of a fire when it comes to Lipo batteries, i do charge and sometimes store my Lipo batteries in a Lipo bag (which is better than nothing)
Which brand of batteries do you prefer? I like Venom Power but the Lipo batteries I have are by Lectron Pro. Curious on which brand you prefer as you seem to have a lot more knowledge on this.
Appreciate your patience with me, as i clearly need to read up on this stuff.

I don't really have a favorite for batteries. The last ones I bought for myself were Intellect/IP and Sunpadow, Next ones might be same, might be different.
For chargers I've been a long time fan (and user) of iChargers by Junsi. I own a 406 Duo and an X6, but they all require a separate power supply, so some people find that inconvenient. I've seen people at our track, using ISDT chargers, not sure chich models though, but they seem nice as well. But there's a lot of threads on rctech about which charger to use, beyond a single guy's (mine) experience.
