Amptron 36V 20A AC-DC Battery Charger FAQs
1. What batteries is this charger suitable for?
It's built specifically for 36V LiFePO4 lithium batteries and delivers the voltage and current profile those cells need. Don't use it on other chemistries or voltages, a charger matched to the battery is what protects the cells and gets you the full service life.
2. How long does it take to charge a battery?
At 20A output it will take a 100Ah battery to full in around 5 hours. Larger banks take proportionally longer. It runs from standard mains power at 200 to 260V AC, so you can plug it in anywhere there's a power point.
3. Do I need to watch it while it's charging?
No. It uses smart multi-stage charging with automatic shut-off, and it will disconnect by itself if it detects a fault and reconnect once that fault clears. Plug it in and leave it to do the work.
4. What warranty does it come with?
Amptron provide a 2 year warranty from the date of sale on this charger. That sits alongside your rights under Australian Consumer Law rather than replacing them. Keep your proof of purchase in case you ever need it.
