I'm surprised nobody has started a thread with quality/cheap -non/diy- chargers as we've done the same with controllers and what not and showing the insides etc...
But I'm trying to understand why 48V chargers ranges from output voltages of 48V all the way up to some hardcore/high end ones of 58-60V.
So if I'm understanding things correctly- For example why don't we take a 48V ping battery 20AH.
Charging it with the "54.6v 2.5amp adapter" will bring it to a lower overalll capacity (80ish%) but extends many more cycles cause the lower voltage. Assuming an almost dead pack would require 8 hours of charging- 20ah/2.5amps.
Charging it with the "58v 5 amp adapter" will give me a higher overall nominal voltage and higher capacity but give me less overall cycles. It would also charge it in 4 hours.
Is my understand incorrect at all? I think my issue is that I don't understand why the total AH matters besides taking longer to charge, why does the voltage itself make a difference if I'm doing a 10 or 20ah battery? (I've seen people say this is a 48V 10ah charger or a 15ah charger)
