hello everybody,requirements:
1. Three flat Lithium battery 3.7 voltare
2. Battery management circuit compatible with x230
Doing:
- Put all to HDD bay
- figure out which pins on the docking connector correspond to the battery pack's positive and negative terminals and data channel (for the battery management circuit), then solder wires (thick ones for the +/- terminals and thinner ones for battery data) to connect them to the pack in the HDD bay.
some guys instruct me modding a power bridge for x230 as above. He also told me to look for the x230t-battery-managerment-circuit then testing whether it fix to HDD bay. Is there anyone had the dimention of that thing? I want to DIY, so any advices is welcome so much.
again, thank you for all your information.
