Can a 48V 12Ah Battery Be Replaced with a 48V 20Ah One?

[AidenFitz]

48V 12Ah battery can be replaced with a 48V 20Ah one, which has no impact on the battery itself. However, it will place a heavier burden on the charger. Currently, if it's for temporary use, you can continue using the original charger. But if conditions permit, it's recommended to purchase a higher-power charger that matches the battery's current more closely. Below is an extended explanation: Specific reason: It is commonly thought that a charger with a lower ampere-hour (Ah) rating cannot fully charge a battery with a higher Ah rating. In fact, the opposite is true—not only can it fully charge the battery, but it may even overcharge it, albeit at a slower rate. Conversely, a charger with a higher Ah rating charging a battery with a lower Ah rating may not fully charge it but will charge it faster. Therefore, a 48V 12Ah charger should not be used to charge a 48V 20Ah battery, as overcharging may cause the battery to fail.
