Chargers
Williamson Electronique can offer chargers to match the rechargeable packs we design, notably based on Li-ion, NiCd, and NiMH technologies.
We also design more complex chargers intended for very specific applications, including for expeditions using our energy cases.

User interface
Start the charger
- “Charger”: the LED lights red for 0.5 s then turns green
- “Charge status”: the LED lights orange for 2 s then changes to another color according to the charge level (precharge/charging/complete or failure)
Charging status by LED
- Green flash (1 s): charging in progress
- Fast green flash (0.2 s): pre-charging in progress
- Solid green: charging complete
- Orange: thermal fault or DC-side short circuit
Charger operational status by LED
- Green LED on: incoming VAC OK / Charger OK
- Red LED on: charging failure (voltage control)
