Note: A BMS with cell balancing and overvoltage/undervoltage logging is required to prove suitable usage of the cells.  Please see the Smart Daly BMS (must be programmed correctly/purchased through Solar 4 RVs) or REC BMS units.

1. Purpose
The primary purpose of this Warranty is to clearly define the matters related to warranty policy of Products.

2. Warranty Condition
2-1. Warranty Period

3. Performance Warranty (Standard)
The product retains at least 80% of Nominal Energy for the either 8 years after the
date of the invoice date when the battery system is operated under a normal use followed by the specification and the manual.
The term “Nominal Energy” herein means the initially rated capacity of the Products as printed on the label of the
Products. The precondition of the valid 8 year Performance Warranty shall be as follows:

(ii) The energy throughput is less than values in table below:
Capacity measurement condition:
- Ambient temperature: 25~30℃
- Initial battery temperature from BMS: 25~30℃
- Charging/discharging method
- Charge: (0.5)CC/CV (Constant voltage (3.65)V, Cut-off current (0.03)C)
- Discharge: (0.5)CC (Cut-off voltage (2.5)V)
- Current at (0.5)C: (80)A 
- Current and voltage measurement at battery DC side

4. Out of Warranty Policy
Product damage which is not caused by seller, a charged service can be provided, including all the expenses of such
as material cost, labor cost, warehouse cost, transportation cost, customs duties, analysis cost, management cost,
