I have recently made the proposed battery. 4x 32700 liitokala LFP cells 6500mAh. I decided not to use a BMS for this battery for now, because I am going to use it as an experimental battery. I might add a BMS for it later. Until then, I will charge and discharge it with care while experimenting.

I am indeed also a little worried about weather 1P will be enough CCA. The annoying thing is I can almost never find ratings for CCA, like you always see in lead-acid specs. About lithium not being capable, I have a LiPo (not LiFePO4) RC battery capable of 65C continuous discharge. Also, I...

Hello, As my first lithium battery project, I'm going to build a LiFePO4 1P4S battery to replace the original 12V14Ah 260A CCA lead-acid motorcycle battery. Basically, I only need to battery for starting the engine. After that, the alternator will keep it topped up and provide the power for...

I want to do the same thing. But not with Li-ion, but with 4 LiFePO4 cells in series. Remember where the battery is located. I would not want a sudden lithium fire underneath my butt while riding on the highway. =p I am struggling to find out how much CCA these cells can deliver. My original...

Hey. Very nice. I'd like to save the step file in my "useful for later" folder, if that would be OK with you.
