Sun Fun Kits guarantees purchases made from its website or authorized retailers are free from manufacturer defects and will repair or replace battery and kits that fail to meet specifications at our discretion within the warranty period. Warranty is only offered to the original purchaser and will require a warranty transfer to any user that the battery has been sold to thereafter by the end user (limited to a maximum of 1 transfer). Warranty details are explained below:
DOA Warranty:
The DOA. (dead on arrival) warranty ensures any item sold by Sun Fun Kits arrives in working order (with exception of scratch/dent products), customers have 48 hours to inspect and ensure items are in working order once received. If the item does not work upon delivery, it can be returned to Sun Fun Kits. All D.O.A. claims require the item in question is in the original and non modified condition, furthermore D.O.A. claims require the customer to ship the item back to Sun Fun Kits to receive a refund.
Basic 12/24 Warranty:
The basic 12/24 warranty provides free repair/replacement of items for the first 12 months and a prorated repair/replacement for the remaining 12 months.
Standard 36/60 Warranty:
The standard 36/60 warranty provides free repair/replacement of items for the first 36 months, and a prorated repair/replacement for the remaining 24 months. This warranty also guarantees a full 100% cycle life for the first 500 cycles, 100-90%capacity for the next 500 cycles, and 90-80% life for the next 500 cycles. After approximately 1500-2000 cycles customers can expect between 80-70% of the original rated capacity.
Extended 60/96 Warranty:
The extended 60/96 warranty provides free repair/replacement of items for the first 60 months, and a prorated repair/replacement for the remaining 36 months. This warranty also guarantees a full 100% cycle life for the first 500 cycles, between 100-90% for the next 500 cycles, and between 90-80% life for the next 500 cycles. After approximately 1500-2000 cycles customers can expect between 80-70% of the original rated capacity.
Improper Installs:
Damage resulting from improper installs are not covered under warranty, this includes (but is not limited to) short circuits, reversed polarity damage, not placing the battery upright, excessive moisture, temperatures that exceed OEM thresholds, improperly installed terminal cables, poor ventilation, and excessive vibration.
Modifications to electronic components:
Customer agrees not to perform modifications to battery cells, bms components, case mounting, or any other change that alters the OEM specifications. Doing so will void the warranty.
Changing BMS parameters with unauthorized tools:
Customer agrees to only use official Sun Fun Kits software tools made for IOS / Android / Windows to manage battery systems, the use of unauthorized software tools will void the warranty.
Using battery in non-approved applications:
Customer agrees not to use battery & components in automotive operations such as using it as an engine starting power source (CCA applications), high power applications that exceed 5000 watts total output, subjecting battery & components to unreasonable tests that do not represent real-world scenarios (e.g. putting battery in a cold freezer or oven), using the battery as a power source for DC arc welding. These and other non approved scenarios will void the warranty.
Physical damage and neglect:
Customer agrees any physical damage to the battery systems and components (such as dropping the battery, impaling the battery, submerging the battery in liquid) will result in voiding the warranty. Customer furthermore agrees subjecting the battery systems and components to environmental factors that exceed OEM thresholds (exceeding rated temperature limits, charge/discharge watt limits) will result in voiding the warranty.
Failure to maintain battery:
Customer agrees to perform proper maintenance on the battery. This includes ensuring cycling the battery at least once every 4 months when not in use and ensuring the battery has a 50% or greater charge when kept in storage. Keeping the battery at less than 15% charge for an extended period of time will damage the battery and will void the warranty. Battery and kits must not be exposed to temperatures greater than 110° fahrenheit or lower than 20° for an extended period (greater than 4 hours) NOTE: Sun Fun Kits BMS system keeps an internal log and Sun Fun Kits technicians can determine if proper maintenance was not done.
Normal Battery Aging / Cycle Life:
Customer agrees that normal cell aging and degradation is not covered under warranty. Sun Fun Kits provides battery estimates in technical specifications for cycle information, however, as is the nature of all lithium based batteries, normal use will degrade the battery over time resulting in reduced capacity and output power.
