❓ Q&A – KEY QUESTIONS ANSWERED
Q1: Does this battery have Bluetooth or app monitoring?
A: No. This POERUNI model focuses on core power delivery and reliability without Bluetooth functionality. Status monitoring requires external voltage/temperature meters.
Q2: What charger specifications are required?
*A: Use a 48V LiFePO4 charger with 58.4V absorption voltage. Max charge current ≤100A. Do not use lead-acid chargers.*
Q3: Can it operate in freezing temperatures?
*A: Discharge is safe down to -20°C (-4°F), but charging requires ambient temperature ≥-5°C (23°F). The BMS will halt charging if too cold.*
Q4: Is series/parallel connection supported?
*A: Yes. For 48V systems, connect up to 4 units in parallel.
Q5: How do I check battery health without Bluetooth?
*A: Monitor voltage via a digital voltmeter: Full charge = 54V-58.4V, Low charge = ≤48V. Temperature can be checked with an infrared gun.*
Q4: Can the battery be installed horizontally?
*A: Yes, the POERUNI lithium battery is free from lesd-acid battery safety issues such as battery leakage and battery corrosion, so ti is perfectly
fine to place the lithium batteries in any position.*
Q5: When I recevice this lithium battery, will it have enough power to use it right away?
*A: Our lithium battery has 30% factory capacity, which can guarantee your basic usage at the moment. If you run out of 30% Of power, you
can use solar panels or unility power to recharge your lithium battery.*
