Charge fully (4 hours) before first use.
Charge fully (4 hours) before first use. For off-season storage, maintain 50–60% charge at room temperature. Avoid continuous charging beyond 24 hours — the BMS does not prevent trickle-overcharge damage indefinitely.
How long does the S1 battery last?
The lithium-ion pack is rated for approximately 300 full charge cycles before capacity drops below 80%. At 3 sessions per week, this is roughly 2 years of normal use.
Signs of battery degradation
Runtime drops below 50% of original spec (e.g., under 45 minutes for a model rated 90 minutes), the unit stops mid-cycle frequently, or the app shows 100% charge then drops sharply within the first 5 minutes.
Charging safety
Only use the genuine Aiper charging dock and cable. Third-party chargers may deliver incorrect voltage and damage the BMS. Do not charge if the pack is swollen, leaking, or if the unit was recently submerged in a non-rated depth.
