LiFePo4 battery users

Being able to see the blue tooth on the LifeBlue batteries has been interesting. It is said that lithium can take all that you can throw at it until 100% but that is not true with these. I am topping them off for installing and the blue tooth shows how many amps are being accepted and according to the tech it was important to charge until the acceptance was 0, not just until the meter said 100%. These batteries will say 100% at 13.6/7 volts and then taper the charge rate until reaching into the 14's. The last one was down to 3.5 amps at 14.1v when I had to shut down for the night. The final top off of all three batteries before combining will be done with the system being installed, a 160 watt portable and my Meanwell power supply.

So interestingly enough my Lifelines can take 5 time the charge rate of the LifeBlue. 500 amps per 100 Ah of battery vs 100 amps per 100 Ah of Lithium. Both batteries have a extended time of tapering in the end phase of charging. In theory I could charge the LifeLines in the bulk and most of the absorption stages much faster than the Lithium's could make it to their taper down stage. I say "in theory" because it is not practical to hit peak charge rates off grid or even on grid without special equipment be it the 300 amps the LifeBlue will take or the 3000 amps the LifeLine"s will
