ChargeX does have a more detailed spec sheet than most resellers I've seen. That's appreciated, but also, they say very directly that their unit is a "drop-in replacement" for lead acid batteries. That's a pretty bold claim, considering all the known issues between LiFePO4 and most alternators. Also, ChargeX claims their 100AH can do 1000CCA. Wow. I assume they've tested that extensively, but it immediately implies there's no overcurrent protection engaged in the BMS, which is not a deal-breaker for me. However, I am very curious how high discharge rates affect cycle life. To my knowledge, we have access to cycle life numbers from OEMs, but almost never from resellers, yet more and more resellers are beginning to claim CCA numbers without any clarification as to how starter usage will degrade expected cycle life. If I start a Merc 50HP twice per day for a year, will my ChargeX battery still last for several thousand deep cycles? I doubt it, but I could be wrong. I think it behooves brands who print CCA numbers to test and specify cycle life per X number of starts to simulate the numbers they expect customers to experience through the product's life.
