I would have a few questions about using batteries.
I am building a slider with a Nema 23 and two Nema 17 motors (for sliding with heavy load and two angle of rotations) and I am thinking about the power supply with batteries. As the TB 6600 driver for Nema 23 requires 9 volts minimum, I would like to use two NP-F batteries combined together in serial connection. (14.8 V)
My questions are the followings:
- Are the cheap NP-F batteries on Aliexpress, etc.. reliable or would they explode?
- Is it true that 1C discharge (max current) is safe to use? The 3 motors together have around 5-6 ampers load, so would a 6000mAh battery could serve it?
- If I combine two batteries (3.7V NP-F) with around 3000mAh capacity, it will be 6000 mAh in summary, so would that be enough to use for my 3 motors?
Thank you in advance for your help and advice!
