Product & Warranty
We offer a 5-year limited warranty for all 12V lithium batteries (from the date of purchase). It covers failures due to defects in materials or workmanship under normal use, such as abnormal cell capacity degradation or BMS failure. See warranty terms for exclusions.
Accessories such as chargers, charge controllers, and fuses have warranty periods from 1–2 years, depending on the product. Check the product listing for details.
Email support@sentorise.com with proof of purchase, product SN number, and a detailed description of the issue. We will respond within 24 hours.
Misuse, abuse, water damage, unauthorized modifications, incorrect installation, or use outside the intended application will void the warranty.
No. Warranty applies only to the original purchaser.
Yes, if the product was used according to the manual and verified defective by our technical team.
Yes, within the warranty period and after confirmation of defect. We provide a prepaid label.
All AC-DC and DC-DC chargers have a 2-year warranty.
At present, we do not offer extended warranty options.
It is printed on the battery label and in the Bluetooth App device info section.

Yes, use a LiFePO₄-compatible MPPT or PWM charge controller.
Yes, pair with an inverter and solar or generator charging.
Yes, ensure load and inverter are compatible with LiFePO₄ voltage ranges.
Yes, choose the correct voltage and capacity for your motor.
Only non-life-support devices, with correct voltage/current requirements.
Yes, with a suitable charge controller.
Yes, if the UPS is lithium-compatible
No, our current batteries are not for aerial applications.
Installation, Usage & Maintenance
Yes, same model/age/SOC, within manual limits.
Appropriately rated copper cables with secure lugs.
Yes, always use correctly rated fuses or breakers.
Yes, any orientation is fine.
40–60% SOC, cool dry place, recharge every 3–6 months.
Only with a regulated DC-DC charger.
Only if it has a lithium mode and no desulfation.
Avoid it; recharge before BMS low-voltage cutoff.
Yes, install in a ventilated compartment.
Only if protected from direct rain/sun and within temperature limits.
Troubleshooting & Safety
BMS protection from over/under-voltage, overcurrent, or temperature.
Charger compatibility, connections, and BMS status.
Recharge fully and retest; if still low, contact support.
No, check for loose connections or undersized cables.
LiFePO₄ chemistry is inherently safe and non-flammable under normal use.
Charging: 0°C–45°C; Discharging: -20°C–60°C.
IP65-rated models resist splashes, not full submersion.
Remove all loads/chargers, wait for conditions to normalize, then reconnect.
No, this voids warranty and risks safety.
No, remove the battery from the area before welding.
Recycling & Disposal
Take to a certified recycling facility.
In select regions; contact support.
Yes, it contains no toxic heavy metals like lead or cadmium.
No, it must be properly recycled.

1.Do you offer a warranty? How long is it and what does it cover?
answer：We offer a 5-year limited warranty for all 12V lithium batteries (from the date of purchase). The warranty covers failures due to defects in materials or workmanship under normal use, such as abnormal cell capacity degradation, BMS module failure, etc. Within the warranty period, if the issue is not caused by human damage, we will repair or replace the battery for free. The warranty does not cover issues such as unauthorized modifications, water damage, external physical damage, etc. For more details, please refer to the warranty terms.
中文：我们为所有12V锂电池提供5年有限质保（自购买日起）。质保涵盖正常使用下产品因材料或工艺缺陷导致的故障，例如电芯容量异常衰减、BMS模块失效等 。在质保期内，如非人为损坏，我们将免费维修或更换电池。质保不包括人为改装、进水、外部物理损伤等情况。详见质保条款说明。
2.What is the lifespan of the battery and how many charge cycles will it last?
answer：Our 12V LiFePO4 batteries are designed to last about 5~8 years, depending on the usage environment and frequency. The cycle life can reach 3000-5000 full charges and discharges, and even more cycles can be achieved at 80% depth of discharge (DOD). Even after thousands of cycles, electricity The pool can still maintain at least 80% capacity. Compared with traditional lead-acid batteries, LiFePO4 batteries have a longer cycle life and calendar life.
