Restoring a Bosch SR 7.2 Flexicharge screwdriver and converting batteries to Li-Ion.

3 ай бұрынI bought this non working Bosch 7.2v Drill/Driver from Ebay. It looked in good condition and used two independent 3.6v NiCd batteries which were dead and leaking. I want to convert it to 2 x 3.6v Li-Ion battery power.

the two speed option could cause a problem with one battery becoming flat before the other and reverse charging it. Nice repair.

Yes the two different voltages seem an odd way to get two speeds. I guess the original NiCad batteries would not have cared about a bit of reverse charge. I don't suppose the Li-Ion cells will like it at all.😁

why didn't you use BMS? Using Li-Ion batteries without BMS is dangerous, isn't it?

The BMS is in the charger which is the next video. I do not use BMS for power output as I find they are not very good at managing high power output. I use BMS to charge the battery.
