Can it replace a lead-acid battery of the same capacity?

Yes, it is a 12V 100Ah drop-in replacement for a group-size lead-acid battery, and it weighs far less. Check that your charger has a lithium profile or a suitable voltage setting.

How many batteries can I connect together?

Up to 4 in parallel and 4 in series, for a maximum of 20.48 kWh. Batteries in a bank should be the same model, age and charge level.

What does the Bluetooth app show?

State of charge, voltage, current, power, cycle count and temperature, within about 10 m of the battery. It is monitoring only, not a charger control.

What is the BMS rated for?

A 100A smart BMS, so continuous draw should stay at or below 100A. It protects against overcharge, over-discharge and short circuits.

What should I do if the battery arrives dead?

Try waking it with a lithium charger or a brief parallel connection to a charged 12V battery. If it still reads only a few volts, treat it as defective and start a warranty claim promptly.

Is it safe to mount inside an RV?

LiFePO4 chemistry is stable and does not need the venting a lead-acid battery does, but mount it securely and keep it out of direct heat.
