Where can I find the position to solder the resistor to? I have a little different one

[@RadioGubitel]

Very interesting! I thought the screwdriver batteries were too weak for resistance welding. I used lithium - polymer and a lead battery from a car. When welding, the currents reach 100-300A, won't this quickly make the battery dead?

[@ErCanEverything]

It is possible to speed up the degradation process because I noticed that the battery was slightly warm. It is an 8Ah battery. But to prevent this I will make another adapter, and connect a second battery to the XT60 connector

Yes. This is not a good application for a Li-Ion battery

@@nguyenanhduy7130 pushing it quite hard. This really isnt a good application for any Lithium Ion cylindrical cell. Maybe if you had a bunch of 30T's or P45B's in a large pack but it would degrade them rather quickly. The best way to do it is car starter battery or high C Lipo

[@S-the-simple-engineer]

@ErCanEverything It would be perfect if you could design the case a bit more thicker so that that the wires from the battery could be run underneath the case, so that it could reach to the other end of the board. Hence you could place the board the other way around and you don't have to bring the wires up and curl it like it is now.

[@jonmiller6732]

Good video, I got this and accidentally touched battery with reversed polarity, so the diode at the negative output terminal blew on my board. My mistake. I want to try to replace the diode, and mine is exploded so there is no more cover left to read a marking from. I think it looks like a SS310 Schottky diode in your video. Could anyone who has this please tell me if the diode next to the neg output terminal has SS310 printed on it? Thank You!

[@pontuscannerbo2]

SS510

[@billloveless6869]

Why do you spot weld the battery? Thanks

[@MarioIArguello]

Did I just see a red (+) wire go thru a (Negative terninal) thru hole and vice versa? Soldering that way is risky. I understand that was probably done to match the contact location on the adapter that sits parallel with the control board and will take the tool battery, but you could have routed them other ways to avoid having to go through the solder point of the opposite polarity wire.

[@dosaimre]

That blew my mind as well. You should have placed the PCB upside down to match + and - terminals and not jeopardize short circuit with such relatively high Amperage

[@johnkatir]

well done nice job. Questions: is it works with 4ah battery, the resistor how ohm is it and if i don't put the resistor it is not working? thank you very much!

[@ErCanEverything]

I ordered this module because it said in the description that it works from 8V to 24V, but after I connected it to a 20V battery, the inscription HI appeared, which means high voltage. And so I decided to put this 100Kohm resistor to trick the module that the input voltage is 15V to work. 4A is low and not healthy for the battery. I recently added another adapter to it and connected it to the XT60 connector. That is, I use 2 x 8Ah batteries and it works more stable.

You must use at least 2 x 5 Ah batteries in parallel to be effective. Even 8Ah is weak and I'm thinking of connecting a second battery to the XT60 connector. I used a resistor to fool the module that the voltage is about 15V otherwise above 16V it displays high operating voltage and not working, even though it was stated to work from 8 to 24V. I also use Google translate😁

[@vick_garage]

@@ErCanEverything your battery is 20v Is that low voltage? or higher amperage

[@ErCanEverything]

The battery is 20V 8Ah but when connected it shows 20.5V and it is a high operating voltage for this module. And that's why I put this resistor, to show 15V even though the voltage is 20V😁

I haven't tried this, but for that purpose I think it would need to be connected to a more powerful battery or powered by the optional XT60 connector.

[@ericklein5097]

spot welding copper requires currents in excess of 1200A to 1500A. None of these PCB boards will do copper of any appreciable thickness. You might be able to do thin copper foil if you put a piece of nickel over the top of the weld area

[@memutu]

[@CalibreDesigns]

I'm just about to do the same resistor mod for this exact PCB, albeit one that I've modded for use with Makita LXT batteries. 8-24v as the listing suggests seems to be an oddly specific voltage range considering they won't operate anywhere near that range without alterations. Almost makes me wonder if there was designed to be a menu switch to higher input voltages (Like how multimeters have different selectors for different orders of magnitude of voltage) or even pcb traces that are designed to be bridged or cut. The manual doesn't actually specify an voltage range, other than mentioning the use of 11.5-14.8v car batteries

[@Yossarian-jb3lk]

Did this board work with a Makita 18V battery? It manual says the battery internal resistance has to be between 2.5 and 7 milliohms and all the Makita batteries I have seem to be much lower. Am I going to fry it with a 18V Makita? Did you try it directly connected to the LXT battery?

[@CalibreDesigns]

@@Yossarian-jb3lk I did the resistor mod on two units. One failed, possibly due to bad soldering on my part (Voltage indicator would fluctuate all over the place after soldering the 100k resistor in) The 2nd board was more successful, it gave a consistent reading of 14-16v after the mod, however it only lasted for around 100 welds before the board stopped working altogether. In hindsight I wish I'd just used a small lead acid battery or taken the extra step to incorporate a 20v to 12v step down transformer or similar to give the board what it needed without the resistor mod, although I don't know if the spoofed voltage is what killed it, or if it was as you say with the internal resistance being too low

[@Yossarian-jb3lk]

@@CalibreDesigns Thank you! I believe you may have saved me from zapping one of these units - I suspected that extremely low internal resistance might kill it. I'm testing my 12V Milwaukee batteries now, which may provide enough Ah in parallel.
