Hi all,
i would to explain my problem:
I have an old Makita 8434D that still works perfectly butt not the battery.
I have seen some videos on YouTube and i ordered li-on batteries andbms4s 30A
battery: NCR16850B (4 pcs)
BMS:BMS
I have 2 problems with this setup:
1. If i push the switch to the end, the drill starts a few turns and stops. ( i suppose thestartcurrent if to high and bms shuts down.There are videos on YouTube that show the same problem that I have)
2. If i use the battery without "discharging control from bms" the drill acts normal, but the battery get very very hot. I measured yesterday 80 C . The result 1 cell is dead.
Is my combination BMS/BATTERY wrong ?
Which batteries/BMS are the most appropriate?
Sorry if ido not use the appropriate terms but my knowledge of this matter is almost zero.
I know that a possiblesolution would be to buy a new original battery, but the price is so high that it's not worth itwhile I can make a battery pack.
Thanks in advance for your help.
Kind regards, Tony
