Increase charging current on K8012

Hello,

By changing resistors R29, R30 and R31, would it be possible to increase charging current above 1A?

If that was possible, batteries with capacities beyond the 10-12Ah could be charged also.

T7 (MJ3001 transistor) is rated 10A max., so it is not the limiting component. Does anyone know which are the actual limiting components, if any?

Thanks in advance.
