Choose Your Lithium Battery

Configure your custom lithium battery pack

Describe your requirement in seven steps: the PDF concept for your custom lithium battery pack is generated as soon as you submit, with up to three configurations per chemistry.

How the battery pack configurator works

Seven steps are enough to describe your requirement.

  1. Chemistry and cell selection — Select one or more chemistries from the catalogue, or ask for a concept covering every available chemistry.
  2. Nominal voltage — The voltage you need, in volts (for example 48 V).
  3. Capacity requirement — Enter it in Ah, or let the configurator work it out from the energy required (Wh), from power and runtime, or from current and runtime.
  4. Electronic management (BMS) — Fitted in the pack, or external management if your equipment already monitors the cells.
  5. Physical protection — Heat-shrink wrap, plastic enclosure or metal enclosure.
  6. Physical constraints — Optional: maximum weight, length, width and height.
  7. Expected volumes — Prototype, units per year or one-off order.

Chemistries currently available: LiFePO4, LiPo, NMC, Semi-solid.

What your battery pack concept (PDF) contains

The concept is generated as soon as you submit the form, in English or French. For each chemistry selected, it sets out up to three configurations. Each one shows the assembly (SxPy) and number of cells, the voltage, capacity and energy obtained, the estimated weight and footprint, the discharge current and power, the cell's cycle life and an indicative unit price excluding VAT, with any volume discount already applied. The “cheapest” and “lightest” labels flag the best configurations across all chemistries. If a battery from our catalogue already meets your requirement, the document points it out: it is available with no specific development.

Electronic management (BMS)

Would you like your battery to include a BMS?

What is a BMS?

The BMS (Battery Management System) is the electronic board that continuously monitors every cell in the pack: voltage, current and temperature. It opens the circuit on overcharge, deep discharge, short circuit or overheating, and balances the cells against one another so that none degrades faster than the rest. On lithium chemistries it governs both the safety and the service life of the pack.

Recommended, and essential on lithium chemistries.

Choose this only if your equipment already monitors the cells.

Step 5 of 8

Physical protection

What physical protection would you like for the pack?

The lightest and least expensive option. Suitable for a pack built into equipment that provides the mechanical protection itself.

Rigid protection against impact and dust, with intermediate size and cost.

Maximum mechanical protection and better heat dissipation, at the cost of a heavier and more expensive pack.

Step 6 of 8

Physical constraints

Does your battery have to meet strict physical limits?

When is this step relevant?

Only tick a constraint that genuinely applies — a drone with a capped payload, for instance, or a housing where a single dimension is fixed, such as a narrow but deep compartment. If you have no constraint, leave everything unticked: we will then pick the most suitable assembly without needless restrictions.

Expected volumes

What volumes do you have in mind? This helps us direct you to the right production route.

A single unit, built ahead of any production run, to validate the concept on your equipment.
