Hi!
i have a 24v 200Ah LiFePo4 pack. I used to charge it with RSP-750-27. Its fully programmable charger. I have set it to 29v and it outputs 31.8A. It has a remote disconnect hooked up to the bms. The bms shuts it down when one of the cells hits 3.53v. Its a save value for my prismatic cells (max is 3.65). But lately i have been seen a lot of posts stating it might be better for longevity to set this cutoff value abit lower (3.45 or even 3.4).
Question 1: What is your take on this?
I recently bought a bench charger. Mostly to experiment with individual cells. Do capacity tests etc. But I really like it so far. It can output 0-30v, 0-10A. Now i was wondering, can I also use it to charge my whole pack. Set the bench charger to 28.0v. (Of course with a remote disconnect controlled by the bms). It only outputs 30% of my original charger, so it will take a lot longer. But it has a lot less noice, and uses less power (so i could use a small dedicated generator for it).
Question 2: Are there any drawbacks of doing a slow charge with a bench charger as opposed to my original 32A pumping puppy ?
Thanks!
