04Why AllGrand
Engineered, built and tested under one roof.
Battery systems fail for predictable reasons: mismatched components, uncontrolled processes, unverified duty cycles. Our structure removes those variables.
Talk to our engineers-

10Questions
What buyers ask first.
If your question is not here, send it with the enquiry and an application engineer will answer it directly.
Ask an engineerDo you manufacture the products yourselves?
Yes. AllGrand operates dedicated gel and lithium production bases with in-house engineering, testing and quality control, rather than sourcing finished goods.
Can you build to our own specification?
Yes. OEM and ODM programmes cover private label, custom enclosure, terminal configuration and voltage or capacity variants. Send the requirement and we will confirm feasibility.
What information do you need in order to quote?
The application, nominal voltage, capacity or autonomy target, duty cycle and the operating environment. A duty profile is enough to start; our engineers will confirm the rest.
Which product platforms do you offer?
Gel, lithium-ion, sodium-ion and solid-state battery platforms, supplied as cells, packs, rack or cabinet systems depending on the application.
Which markets do you serve?
AllGrand products are used by customers in more than 100 countries and regions, through distributors, integrators and OEM partners.
Which certifications do you hold?
Certificate scope is being confirmed for publication on this site. The certificates relevant to your product and market are supplied with the quotation on request.
Do you provide datasheets, drawings and test reports?
Yes. Each product page carries a documentation request; datasheets, technical drawings and test reports are issued per model once the requirement is confirmed.
Can you supply samples?
Sample quantities and terms are confirmed per product and destination. Tell us the model and the country and we will respond with the options.
What is the lead time?
Lead time depends on model and volume and is stated on the quotation, so nothing is promised that production cannot hold.
What support do you provide after delivery?
Technical response, spare-part planning and replacement guidance are handled by the application engineering team across time zones.
