BatterySpace.com carrys high quality "High Wattage Charger" for example: 600W, 900W, 1KW, 1.2KW, 1.5WK, 2KW, 3KW, 4KW, 5KW, 7KW, 9KW, 15KW(400V45A), which can charge high voltage SLA, Li-Ion/LiNiMnCo, LiFePO4 battery pack at high charging current.
So how many wattage will be enough ? Here is the formula:
Wattage = Max. output voltage of the charger x charging current / effieciency factor
- Max output = peak voltage x number of cells in serial
- 4.2V/Cell for Lithium
- 3.65V/Cell for LiFePO4
- 2.45/Cell for Lead Acid
- The efficiency factor is around 0.6 to 0.85
For the charger we don’t have on table list yet, we can help you built a customize high wattage smart charger. Our engineer will adjust charging voltage / charging current based on the wattage supply ( 600W, 900W, 1KW, 1.2KW, 1.5WK, 2KW, 3KW, 4KW, 5KW, 7KW, 9KW, 15KW(400V45A)). Please email us (email@example.com). We can provide quotations. Be advised that customized charger takes 2 months and the price will be higher than other.
