AI Customer ServiceIf the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C.

AI Customer Service(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
The charging current depends directly on the capacity of the battery, all other things being equal. When you read literature about batteries, you will come across C-rate. For example: "The battery was charged at 0.5C ." It's not temperature in Celsius, and it's not capacitance in Farads.
Charge Voltage – The voltage that the battery is charged to when charged to full capacity. Charging schemes generally consist of a constant current charging until the battery voltage reaching the charge voltage, then constant voltage charging, allowing the charge current to taper until it is very small.
If minimum current is not noted (it usually isn't), you can often go as low as it makes sense for your use case (but note that at some point you'll be charging less than battery self-discharge - where "charging" doesn't make sense anymore). In practice, you probably wouldn't go below 0.1C, unless you had a reason to.
Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises. When the battery reaches its full charge cut-off voltage, constant voltage mode takes over, and there is a drop in the charging current.
For a 60v 20ah pack, the maximum continuous discharge current can be as high as 50 amps, but the charge current is max 5A. Why?? The connections between cells clearly can support high currents, otherwise it cannot discharge with 50A without damage. Why is the charging max so low and what happens if I push 25A with a powerful charger? Thank you.
