    Replacing UPS lead acid batt w LiFePO4

    Now I get it. Although this SLA battery datasheet didn't mention the current discharge, 40A - 80A discharge is the standard range for an SLA battery. On the other hand, an LFP battery is typically capped around 7A. Everything makes sense now. Thanks a lot, @Supervstech

    Replacing UPS lead acid batt w LiFePO4

    Hi @nbtesh, thanks for your reply again. The Nermak datasheet says the battery can only handle 20A for less than 5 seconds. Question #5 What would happen if someone pushed beyond that limit by accident? 500W means that the battery can discharge at 500W / 12V = 42A. @Supervstech mentioned...

    Replacing UPS lead acid batt w LiFePO4

    Hi @nbtesh, Please correct me if I am wrong. Based on the datasheet of the UPS and its battery, the UPS uses two 12V / 7Ah lead acid batteries. Theoretically, these batteries can deliver 24V/7Ah = 168Wh (in series) or 12V/14Ah = 168Wh (in parallel). Besides, the UPS can handle a max load I am...

    Replacing UPS lead acid batt w LiFePO4

    Just wondering, how do you make sure a battery can handle 300-500 watts from their spec sheet?

    Replacing UPS lead acid batt w LiFePO4

    Hi, I have been following your discussion, but I am still unsure if I should replace my UPS battery with the LiFePO4 battery. Some of you talked about floating voltage, maximum draw, ...etc. But I am not sure what to look for in the product specification. Can someone please help me out? I am...
