Are lithium batteries worth the cost?

. . . At ~13.6VDC from my 45A-capable Progressive Dynamics converter/charger with very short 4AWG wiring, my 100Ah x 2 BattleBorns at 50% SOC choose to pull ~4A total. At 13.6VDC, their thirst for current is minimal . . .

Interesting. We have the same PD 45a converter and get a steady 20-25a of charge current at 13.6v charging our 200ah LifePo4 pack from 10-90% SOC. Get 45a charging at 14.4v from 10-95% SOC.
