battery voltage discharge rate

[Bill 112]

I have 3 lipo 12v batteries...wired in parallel. They are 208 ah each. Giving me 618ah at 12v. I believe this is correct. When I hook a load to them. What will the voltage do with the 3 batteries in parallel. Will it drop drop the same as one battery at 12v. Drop slower or drop the same speed.

Slower, by 1/3.

lipo

Lithium polymer?

Or Lithium iron phosphate?.
LiFePO4

Big difference.

Will it drop drop the same as one battery at 12v. Drop slower or drop the same speed.

The self discharge for all lithium chemistries are rated as a percent from what I have seen. And 2% is the general consensus.

They are LiFePO4 batteries

LiFePO4 batteries have a very flat voltage "curve". You may find that there isn't much change in voltage until you get to the extremes.
