FAQ
Planning your custom project.
When should we involve Meanwatt?
Early involvement is useful before the enclosure, charger and connector are frozen, but existing designs can also be reviewed for fit, availability or performance issues.
What files help the review?
A block diagram, load profile, mechanical envelope, connector pinout, charger details, environmental targets and forecast quantities are the most useful starting materials.
Does integration mean complete product design?
Not automatically. Our core role covers the power subsystem and supply coordination. Any wider electronics, firmware, industrial-design or certification responsibility must be explicitly scoped.
Can you replace an obsolete battery?
Yes, subject to evaluation. We compare voltage limits, capacity, current, charging method, communications, dimensions, mounting, connector and safety requirements before proposing a replacement.
How is a design frozen for production?
The electrical specification, approved cells, BMS, mechanical drawings, connector pinout, label, test criteria and change-control process are agreed before pilot and repeat production.
