On the graph below - take the 3.8V / redline (1A) intersection. Draw a line vertically downrads to 3.6V. This about intersects the 5A yellow line. This suggests an "OK max" discharge rate is 5-1 = 4A. That''s about 4A/3.5Ah or ~= 1.15C for this cell - ie, about right for an unknown capacity and capability cell.
Determining the maximum charging currents of lithium-ion cells

Yes, charging a Li-Ion cell at constant voltage without ever terminating the charge will likely destroy the cell. What will happen is that your battery will get (maybe slowly) to 4.0 V, and, if the voltage stays, the charging current will gradually decrease, and will decrease to zero.
What is the Maximum Charging Current for a 200Ah Battery?
The maximum charging current for a 200Ah battery typically ranges from 0.5C to 1C, which translates to 100A to 200A. This means that for optimal charging, you should aim to charge your 200Ah battery at a current of between 100A and 200A, depending on the specific battery chemistry and manufacturer recommendations.

I know the exact values depend on the specific battery used, but is there a general rule for the maximum charge current (as a function of the battery capacity) for each of the mainstream battery technologies (NiCd, NiMH, Li-ion, Li-Polymer, lead-acid), for normal and fast charging? The typical capacity I''m going to use is 10 - 40 Ah.
Battery C Rating Chart
A battery with a 1C rating can be charged at a current equal to its capacity. For example, a 1000mAh battery can charge at 1000mA (1A). Charging at higher C-rates can reduce charge time. However, this may affect battery life. A battery rated 2C can charge in half the time, but frequent fast charging can lead to wear and tear.
