Can I use my hitec 4x charger? Has any one done this? When I try the charger will stop short , giving me a brake in connection sine.

So the craftsman battery is a li-ion 1.5ah. So I set my hitec 4x multi charger to 1.5 and set the voltage/cell count to auto. The batter is 19.2volts , but in the pre sets on the charger, there isn't a set for that voltage. That and I have no way of looking inside of the pack. It has safety screws/ torques . Is there some cind of Circuit interrupter built into these packs?

Most hobby Chargers will want a balance plug connected to monitor each cell. The craftsman battery probably has no offerings here. Perhaps they charge and balance internally.

Enjoy things that money can buy IF you don't lose the things money can't buy.

so if I set the voltage accordingly for this pack. But instead of using the li-po pre sets on the charger I could go into a ni-cad pre set and set the voltage to 1.5c and the internal Circuit interrupter would not trip. Yes ,no?

Watch at YouTube

As suspected, there is an entire charging, balancing, and BMS unit installed inside the battery case.

Don't see how a hobby charger could possibly work in this situation.

I believe you just answered your own question.

So then I should be able to set my chager up at what ever is the desired voltage and the end milliamp capacity. For example , if I set the chager in ni-cad at 1.5ah = 1c on a 1500mlh . Then the regulated pack/balancing pack will do the rest, the charger will read the end charge and stop. Yes or no.?

Just currious, how that worked out for you being you seem dead set on not using the propper charger intended for these types of batteries. Myself being in the construction trade, i have a bunch of these tools, makita and dewalt, all have their own charger bases. Never once have I tried to rig up my rc charger system to charge them.

kinda off topic here as not a craftsman tool battery, but I had a led light that had been given to me by my father with no charger. I was unable to get any info from the net or to get the manufacturer to reply to questions on their site .I had the same issue light had quit working and I suspected battery issue .Since I had no charger or matching plug for it from any of my other tools it may have been junk . Well the other night I took the light apart and determined it was a 1 cell 1400 mah lipo 3.7 volts . The connector on the battery that connected to the board inside the light matched one on my charge octopus so I was able to charge it now the light works great again took 1238 mah to completely charge mine, so he may still be able to figure out a way to do it .just be careful not to cause a fire or damage by doing something unsafe or unmonitored just my 2 cents

True, but thats in a pinch. But unless it is the absolute last choice as was in your case, why would you want to do that if the tools have a specific charger , and you would not have to disassemble the pack just to charge it?

Very true the correct wall wort would have made it much simpler and in my case the light would not have sat on the counter in the kitchen for the last month and a half while I searched for options . My father had no idea that it would be hard to get a charger because he had picked up the light at a church rummage sale. Sounds like it should be fairly easy to get the correct charger in the case of the craftsman power tools .

No, you can't.

That battery, as well as many other tool battery already have a "smart" charging circuitry built in. It needs the proper voltage-amperage to feed it. You need to find out what the original charger puts out and match it with a "dumb" wall wart plug in.

Any "smart" charger needs to be connected directly to a battery in order to run its programmed safety sub-routine to charge them. If not directly connected, you get your results.
