Charge time by charger wattage
| Charger | Power | Full charge (0-100%) |
|---|---|---|
| Trickle charger | 100W | 67 h 46 min |
| Standard charger | 500W | 13 h 33 min |
| Fast charger | 2000W | 3 h 23 min |
| Ultra-fast charger | 3000W | 2 h 16 min |
Battery capacity: 4.8 kWh · Chemistry: li-ion
Lead-acid batteries should never be fast-charged past what the charger's built-in profile allows, since excess current causes gassing and permanent capacity loss.
This is a large battery: budget several hours, often best left charging overnight or during the day while you're not using it.
With the fastest charger listed here (Ultra-fast charger, 3000W) it takes about 2 h 16 min. With the slowest (Trickle charger, 100W) it takes about 67 h 46 min. High-capacity lithium battery designed for off-grid camper vans and mobile living applications.
Frequently asked questions
- How long does it take to charge a Camper Van Lithium Battery (48V, 100Ah)?
- From 0% to 100% with the standard 2000W charger, it takes about 3 h 23 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Can I use a higher-wattage charger to charge it faster?
- Yes, as long as the charger is compatible with the device's connector and voltage. The battery's own charge controller limits how much current it accepts, so a more powerful charger reduces time mainly in the 0-80% range; above 80% lithium-ion packs taper the charge rate for safety regardless of charger wattage.
- Why does charging slow down near the end?
- Lithium-ion batteries charge at full power up to about 80%, then switch to a slower "taper" phase that protects the cells from stress at high voltage. That's why the last 20% often takes nearly as long as the first 80%.
- How is this charge time calculated?
- We divide the energy needed (4800 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
