What Moves Your Quote: Ten Cost Drivers
There is no published list price for a custom pack, because ten variables change the number at once. Each card below names the driver, why it moves your quote, and what to send so the quote comes back accurate the first time.
1
Cell chemistry and grade
LiFePO4, Li-ion and other chemistries carry different voltage behaviour, cycle life and safety profiles. Brand-new Grade-A cells are the grade the reference cell credits with 6000 cycles.
Send us: required chemistry, and whether the cell must be brand-new Grade-A re-wrapped alternative is acceptable.
2
Cell format and dimensions
The 32800 cell measures 32.6 × 80.8 mm max. Format decides how many cells fit in your enclosure envelope and how the pack is laid out.
Send us: your enclosure envelope with the maximum cell diameter and height you can accept.
3
Capacity and cell count
Capacity per cell — 7200 mAh at 0.5C discharge on the reference cell — sets how many cells a pack needs to hit your target Ah or kWh.
Send us: target pack voltage, capacity or energy, and the physical space available.
4
Series and parallel arrangement
The S/P count sets pack voltage and how current is shared across cells, which in turn caps your continuous and peak discharge budget.
Send us: required pack voltage, continuous current and peak current.
5
BMS complexity
Balancing, temperature sensing, communication and protection thresholds all add components. The reference cell works to a 3.65 V charge cut-off and a 2.0 V discharge cut-off.
Send us: current limits, whether balancing, temperature sensing or a communication protocol is required.
6
Connector and cable assembly
Terminals, wire gauge, harness length, fuse and a sealed connector are labour and material, and they are the parts buyers most often leave off a first drawing.
Send us: connector type, cable length, wire gauge and any fuse or switch requirement.
7
Enclosure and tooling
A standard housing keeps cost low; a custom mould is a one-time tooling item that is then amortised across the order volume.
Send us: enclosure drawing or 3D file, material, and any ingress-protection requirement.
8
Certification scope
Which markets you sell into decides whether the pack needs the CE, CB, IEC62133, UL, PSE, RoHS or REACH file, and whether extra testing is required for your configuration.
Send us: destination markets and the exact certificate list your buyer or customs agent requires.
9
Packaging and freight class
Lithium shipments travel with UN38.3 and MSDS documentation, and the packaging spec plus transport mode both feed into the delivered cost.
Send us: destination, air or sea mode, and your packaging or pallet requirements.
10
Order quantity and repeat schedule
A single project batch and a recurring annual schedule price differently, because tooling, certification and setup costs spread over different volumes.
Send us: first-order quantity and your annual forecast or repeat schedule.
Send your specification and we will return a line-item quote broken down by the drivers above.
