Hello,
I'm new in the battery world. I've found online a 12S (44.4v) battery with 28000mAh and 25C which does not have an integrated BMS. Talking with the seller, he said that I would need a smart charger. For me the space it's not crucial but the price is as I'm on a tight budget.
The battery costs 378USD but the smart charger alone is around 300USD which is quite a lot. A similar battery with integrated BMS is around 500USD.
The battery will be connected to an ESC which will drive a 44.4V - 100A nominal current motor electric motor
I need some help regarding the following questions:
- from what I've understood, I either need a BMS or a Balance Charger, and not both?
- Would it be better to buy a battery with a BMS as it also controls the battery while connected to the load?
- Is the BMS not necessary while using the battery so I'm better off purchasing a smart charger?
- Doing the math it would be cheaper to buy a battery integrated BMS for 500 usd and buy a "dumb" charger for 70USD, as the dumb charger also weights a lot less.
- Would you suggest buying the 378USD 12S(44.4V) - 28000mAh battery and than buying a BMS to go with it? if yes what are the parameters I need to look out for?
- Why do some people, when referring to 12S, say that the voltage is 48V and not 44.4?
Thanks,
