This 20ah has been an ideal battery (up from 12ah) for portable water pumping operations on the property for the garden, water transfer, etc. It will easily power a 12v 7amp 7.5 gpm diaphragm pump, pumping 600 gallons of water continuously with power to spare. I exhausted it completely with an inverter to power a mini PC to see what it would endure, replacing 268 amp hours for its 256 ah rated spec (a one time test!) The screw/10mm post terminals are secure and convenient.
What to watch with an LiFePo4 is cold charging and I keep max discharge to 10% remaining and like to recharge at 20%. They do not like and the BMS will prevent, charging below 32F.
Another convenient power source for a portable freezer operating @ 3.4 amps for about 10 hours at a 50% duty cycle. Typical recharge rate of 4 amps with a max of 10 amps. I will use 4 amps when I have time, and 7 to 8 amps when I need a faster charge. If you take 20% of a typical 100ah battery (20ah) costing $345, the price for this one seems reasonable.
