1. Introduction to CellPac BLOX

How does CellPac BLOX work?

This handbook is a portfolio of all combinations of cells and PCM which can be ordered under the CellPac BLOX program. We have already reviewed and tested these combinations in detail to ensure a good fit between the cell and safety electronics.

On the following pages, there is detailed information about each cell and the cell performance as well as the configurations which can be ordered of that type. On each datasheet page, there is a CellPac BLOX Order Reference Number (CPB XXXX) and MOQ for that individual battery.

    B --> C["Agree Volumes & Pricing"]
    C --> D["Place Sample Order"]
    E["Test & Approve Samples"] --> F["Place Volume Orders"]
    F --> G["Place Volume Orders"]

The VARTA CellPac BLOX distributor will quote the customer for samples, mass production and any NREs if necessary. All that needs to be provided to quote you is:

CPB Reference Number
▶ Wire & connector requirements (wire length & connector type)
Mass production quantities for pricing determination

Once orders are received for samples, VARTA will work on a battery drawing and build samples of the battery, which will be shipped normally within 3 weeks from order. After internal customer testing of the samples you can send the approved drawing back to your distributor and order the agreed mass production quantity with any necessary NREs, which were already determined. The provided drawing of the battery is the master document and defines the battery (check it carefully!). Lead time for mass production is typically 12-16 weeks. Please note that this will be longer if certification such as IEC62133 edition 2 is required for the battery pack.

2. FAQ - Frequently Asked Questions

How many samples can be ordered?

Up to 25 samples can be ordered to test and validate the design.

How long does it take?

Once POs are placed and your project is started, a technical drawing of the final battery and the samples will be provided for you for drawing approval and samples testing. We aim to ship the drawing and sample bundle within 3 weeks.

For the mass production order after your approval the typical lead time can vary between 12 and 16 weeks for the mass production quantity. Actual lead-times can be checked via your distributor when you discuss your individual requirements.

I need a high volume, is special pricing available?

CellPac BLOX can be ordered at any volume above the MOQ but fits best to OEMs requiring volumes of 5000-50k pcs. Pricing can be negotiated with your distributor to reflect commitment levels.

Why is there an NRE (Non-Recurring Engineering) charge?

Your battery will be a new design, with its own part number. As well as the new drawing, there will be manufacturing and quality documentation established. Fixtures will be produced to ensure repeatable quality and UN38.3 testing and certification is mandatory. NRE is kept as low as possible and avoided completely in many cases.

Can the CellPac BLOX battery be certified for special requirements, such as IEC62133 edition 2?

Yes, additional certification is possible for medium-to-high volume projects but more time and effort is involved. Please discuss your individual requirements with your VARTA representative.

6. Design Tips for VARTA CellPac BLOX Battery Packs

In general, we strongly recommend for any design-in to consult the sales engineer of the distributing company. For applications with special requirements or environments which go beyond the specified conditions, CellPac BLOX batteries will not be suitable.

To support your own design-in process, we offer the following tips, to help avoid the most common issues which can occur:

1. A lithium rechargeable battery is a "living" product combining mechanical, electrical and chemical engineering disciplines. Its performance is highly dependent on how it is treated, as shown in the technical data within this handbook. The limitation of our own data is that it is generic and therefore in most cases only indicative of reality. For CellPac BLOX batteries you will get samples to test its performance specifically for your application before finalizing your design and moving to mass production.

2. For pouch-cell battery designs, it is important to take good care of the case during handling or installation. The cavity should not contain any protrusions which may dent or pressure the pouch surface and should be big enough to contain the cell with room for a little swelling over lifetime (0.1-0.2mm per cell, unless stated on the Product Information Sheet).

3. To secure pouch cells comfortably, especially in cases of too much space, a suitably-sized adhesive pad secured inside the battery cavity is recommended to a good fit.

4. It's important to be aware of any standby-mode or continuous-drain which your application may put on the battery (e.g. clock, memory or data functions), especially with respect to avoiding over-discharge. Some batteries may have relatively low charge on arrival or at the time of installation to your devices. Long-term storage without re-charging, especially after full discharge of your application, may risk bringing the battery into "deep-discharge" at a very low voltage below 3.0V. This can cause long-term performance problems, swelling and in very extreme cases, lithium plating within the cell. A half-charge is an ideal condition for storage in general, but if your application does drain the battery in standby or "off" modes, the storage lifetime should be calculated and managed.

5. Avoid extreme or tight bending of wires, especially at the connector point or where the wires are soldered to the battery electronics.

6. The safety electronics of the PCM included in the battery are intended as a final safety function. They should not be relied upon within the application design to control the application behaviour. The electronics within the application design and charger design should normally control all functions of the application without any trigger to the battery safety functions. The battery safety functions are intended to intervene in the event of a failure of the normal electronics function of the application and/or charger.

7. For installation of pouch cells, especially designs with no connector, take special care to consider the installation process. Dropping cells directly onto hard surfaces may damage them and cause swelling over time. If cells are dropped before installation, it is generally recommended that they are removed from your production and not installed. Soldering processes should not be done too close to the PCM or pouch to avoid any risk of heat damage. For example, to trim wires down to a very short length would bring the solder point very close to critical components. The safety function of the PCM could be compromised or the cell itself could become damaged.

8. Sharp ribs or corners within the cavity should be avoided where possible. In a scenario where your application may be dropped (a high risk for handheld devices especially), these can cut into the cell during impact.

Charging

Fast charging (CC/CV charging) can be achieved in a temperature range of 0 ... +45°C. The current of charging needs to be limited to individual specification of the battery selected.

Limiting factors may be the PCM, wire connector assembly or the cell itself. In order to avoid overcharging along with damaging the battery or even hazardous situations, the charging voltage has to be limited strictly to 4.2 V per cell, see the individual specification for your battery choice for the most in detail information. It is recommended to terminate the charging either after 3hrs and/or after the charging current falls below 0.02 C.

The charging process is illustrated below showing current and voltage of a LPP 443441 S battery using 1 C I/V - charging.

Cell charging characteristics

Discharging

Since all CellPac BLOX batteries are delivered with a safety-circuit, the max. current rating established in the specification must be observed. There are two levels of overcurrent protection of which the first one will lead to a reversible interruption of current supply, while exceeding the second level will make the battery unusable permanently.

Please see the individual Product Information sheets for details of the safety parameters built into our modules which are set differently depending on the type designation.

7. Reliability and Life Expectancy

VARTA CellPac BLOX batteries combine maximum safety with top-performance and reliability.

Cycle life is expected to be 300-500 cycles with a remaining capacity of 70% - 80%, depending on exact model.

Typical cycle-life at room temperature (20°C) LPP 523450 S

8. Safety

All CellPac BLOX batteries are equipped with an electronic module for protection against malfunction of charging and discharging, misuse and abuse. Moreover, cells are selected which provide the best of performance data combined with excellent inherent safety features for usage within reasonable boundaries of specifications. To cope with any foreseeable abuse of our batteries, we have implemented a number of safety criteria which are usually multi-redundant when implemented together with a carefully designed application device and related charging circuitry in particular.

It is VARTA Storage policy to have all new cells tested and listed/recognized by UL (a worldwide acting, non-profit organisation in the field of consumer safety protection), according to the standard UL 1642. Relevant testing requirements, which represent to us the minimum level of safety testing, are given in the following table:

Test	Description	Required results

9. Storage

Where possible, storage under fully charged state (CC/CV 4.2V, 3h) should be avoided to maximize longevity. Trickle charge, common in aqueous battery systems (Ni-Cd, Ni-MH), is strictly forbidden to avoid performance issues and safety concerns.

10. Transportation of VARTA CellPac BLOX Batteries

Rechargeable lithium ion batteries manufactured by VARTA Storage are considered to be UN 3480 Lithium Ion Batteries, and are tested according to 38.3 of the "UN Manual of Tests and Criteria" for compliance with the requirements of special provisions ADR 188, IMDG 188, DOT / 49 CFR § 173.102, and the requirements of IATA DGR packing instruction 965. Positive test results as well as other relevant information required for transportation are stated in dedicated "Declarations of Conformity".

Onward transportation of CellPac BLOX batteries in original VARTA packaging is permitted provided the shipment is made in accordance with the transport rules in force at the time of shipping. Repackaging and onward shipment should only be done by trained personnel in accordance with the latest transportation regulations in force and is the sole responsibility of the shipping party.
