What our Experts Think

Q&A

Q: What is the Abyss Battery AB-36V105-BT used for?
A: A high-capacity 36V 105Ah LiFePO₄ lithium battery designed for golf carts and electric utility vehicles, delivering long runtime, strong acceleration, and maintenance-free performance.

Q: What are the key specifications of the AB-36V105-BT?
A: 38.4V nominal voltage, 105Ah capacity (~4.0kWh energy), up to 100A continuous discharge, and 700A peak discharge for short bursts like hill climbs or acceleration.

Q: What does it replace in a golf cart?
A: It replaces three 12V lead-acid or AGM batteries wired in series, reducing weight, freeing space, and improving efficiency.

Q: Does it support Bluetooth monitoring?
A: Yes, it includes a built-in Bluetooth BMS to monitor state of charge, voltage, temperature, and battery health via mobile app.

Q: How long does it last?
A: Around 3000 cycles at full depth of discharge and up to 6000 cycles at partial discharge, significantly longer than traditional lead-acid batteries.

Q: Is it suitable for harsh conditions?
A: Yes, it is IP67 waterproof and designed for wide temperature operation, including hot climates and outdoor use.

Maintenance Tips

• Use correct charger profile: Charge only with LiFePO₄ charger (43.2V max). Avoid lead-acid/AGM chargers to prevent BMS stress or under/overcharge.
• Avoid deep discharge: Recharge before dropping below ~20–30% SOC to maximize cycle life and prevent voltage sag under load.
• Temperature-safe operation:
• Charge: 0°C to 55°C
• Discharge: −20°C to 60°C
• Respect BMS limits: Keep continuous draw within 100A max discharge rating to avoid shutdown during hills or heavy load.
• Bluetooth monitoring: Regularly check SOC, voltage, temperature, and cycle data to detect imbalance, overheating, or abnormal drain early.
• Proper storage: Store at ~50–70% charge in a cool, dry environment; avoid leaving fully charged for long periods.
• Terminal care: Inspect and tighten M8 terminals periodically—loose connections can cause heat buildup and voltage drop.
• Water & corrosion control: IP67 sealed, but still rinse salt/dust buildup and avoid pressure washing terminals or vents.
• Parallel setup (if used): Only connect batteries at equal voltage/SOC to prevent imbalance stress on BMS.
• Regular cycling: Occasional use improves cell balance and long-term performance stability.
