Not to mention a product name, but I inquired about a supposed Li charger brand in the context of an extended charging period and was told that the batteries BMS would guard against an overcharge scenario...But not all Lifepo4 batteries have the same voltage cut-off spec..In the case of a battery cut-off voltage higher than that ofthe charger output, the BMS will not be a sufficient safeguard to avoid overcharge..
The point here is that there is little convention on this issue, and a given charger should be matched with a given battery’s charge specs, and to understand that the BMS is not for controlling thenormal charging regiment. JMO - please feel free to comment!
