Inclusions:

1. Assembled cell-pack(s)

2. Cell voltage sense - balance wires:  A "Deutsh" style connector is provided on each pack.

Assembled by Solar 4 RVs in Melbourne Australia using CALB 163Ah cells for use with a REC BMS.   The price includes assembly into a 3D printed enclosure up to 16-cells long.  If the weight and/or dimensions of a large single pack don't suit, then please let us know as we can supply a "16-cell pack" as 2x 8-cell packs or 4x 4-cell packs, or a combination of the two.  Just let us know by email.

Notes on why and how cells are wired inside the packs:

One LiFePO4 cell, also frequently called LFP, has a nominal voltage of 3.2V so a pack of 4-cells wired in series has a nominal voltage of 12.8V, but is normally called a 12V pack.  Similarly, 8-cells in series provides a 24V pack, 16-cells a 48V pack, etc.   Capacity (Ah) wise, 4-cells each of 163A provides 163Ah at 12V, 8-cells provides 163Ah at 24V, etc.   In most batteries, there are multiple small cells wired in parallel, for example common 12V 100Ah LFP batteries would likely be made up of 4x 25Ah cells wired in parallel to provide 100Ah at 3.2V and then 4 of these are wired in series to provide 12V, which is abbreviated to 4P4S.   An major benefit of paralleling of cells is lowering the internal resistance of the battery allowing for higher charge and discharge currents.

8 Year Limited Warranty on CALB Cells (only when used with a REC BMS )

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

2. Warranty Condition
2-1. Warranty Period
The Performance Warranty for the CALB cells is valid for 8 years from the invoice date.

2-2. Limitation of Warranty scope
Liability under this Warranty shall be limited to replacement, repair, refund and compensation. Replaced or
repaired Products shall be warranted for the remainder of the original Term of Performance Warranty. In any event, the
replacement shall not justify the renewal of the Term of Performance Warranty.

2-3. Exclusion of Warranty
Damage to the Products resulting from any of following activities is NOT covered by this Limited Warranty:
- Improper transportation, storage, installation or wiring by Buyer
- Modification, alteration, disassembly, repair or replace by someone other than authorised personnel
- Noncompliance with official installation manual
- External influences including unusual physical or electrical stress (power failure surges, inrush current, lightning,
flood, fire, accidental breakage, etc.)
- Use of an incompatible inverter, rectifier or PCS.

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:
(i) The ambient temperature during the operation of the Products shall not fall out of range of the cell specifications in the data sheet
(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,
corporate profits, disposal expense(If necessary) and so on.

5. About Service Products/Parts
Service products/parts are able to be used as new or refurbished condition which performance is equal to or higher
than defective Products.
In the event the Products are not available in the market anymore, the parts may be replaced with a different kind
of product with equivalent functions and performances or refund the remaining annually depreciated value of the
purchase price of the Products during the Term of Performance Warranty as the Compensation Scheme below. The
purchase price mentioned hereinabove means the list price actually paid by the Buyer for the purchase.

- Compensation Scheme in the unlikely case replacement cells are no longer available -
CLASS I : 100% of the purchase price from the initial installation date to 24th month
CLASS II : 75% of the purchase price from 25th to 36th month
CLASS III : 60% of the purchase price from 37th to 48th month
CLASS IV : 45% of the purchase price from 49th to 60th month
CLASS V : 30% of the purchase price from 61st to 72nd month
CLASS VI : 15% of the purchase price from 73rd to 84th month
CLASS VII : 5% of the purchase price from 85th to 96th month
No warranty of performance will be provided from the 96th month

Assembly

The assembly of the cells and BMS is a free service Solar 4 RVs supplies and the warranty provided covers the individual components, not as a single unit.  Therefore, if a BMS failure were to occur, a replacement BMS would be supplied under warranty, likewise if a single cell were to fail, a replacement cell would be supplied to the user.  Solar 4 RVs will replace any faulty cell or BMS into an assembly as a free service if the end user returns the assembly back to base.
