In my experience you will get the best information from a battery supplier tech support person. Thought I had after making the above post. So be careful, be sure you don't hurt yourself of others and go for it. I'm sure folks will think I am too cavalier about a "safety" issue but even the hoverboards failing were only a local fire, not a life threatening explosion. I would be careful to not allow the batteries to build up temperature either in the charge or discharge process. Don't keep your face near the device when running.You are outside, or at least in a large area.The device is always monitored by a human when it is running.to failure.Īgain no hard data, but I think a suitable size electric tool battery would be fine for you use. It seems the batteries have an internal maximum temperature above which they start to self discharge causing more temperature and so on. Our considered involvement was be in the area of cooling the batteries. We've researched electric vehicle batteries. My small Milwaukee Li-ION drill and "saws-all" has been pushed pretty hard (being a small battery, 12V 16Whr) and not complained. Unfortunately I don't have any hard data to provide but I have two bits of information: I think its safe to say you shouldn't use thermal batteries. I should've known I'd be interrogated for saying anything other than, "HoW muCh amP does drill baTterY do?" I'm asking the community amateurs specifically because I know there may be someone first hand experience with unconventional power tool battery usage out there. The manufacturers also don't release this information in datasheets to the public. I've searched the web for hours looking for this information and all I can find is brief articles explaining what amp hours are. The reason I'm asking, besides not having the batteries on hand, is just to get some general information. If the battery can't do that, it'll either trip overcurrent protection or just run at a lower power. All I'm looking for is information on how much current a common drill battery is capable of delivering. If I wanted to break the rules, I'd be using a hobby RC li-po pack that I know would work. Health and safety standards are not the same the world over, what is considered acceptable practice in one territory may be prohibited in another. There may be specific requirements, either stipulated by the university itself or by local health and safety legislation, that you must comply with that people on this site are not going to be aware of. I think that you should be asking your questions to the university safety officer, rather than on an international amateur forum. I'd like to avoid spending a couple hundred dollars on multiple batteries for testing, it's only logical that I'd at least ask before committing to that. I only included the specific battery for reference. I'm not looking for information on a specific battery, just information on batteries in general. I'm sure at least one of a bunch of random people have used a drill battery before. That's likely to be far more useful than asking a bunch of random people here about a very specific battery. It would be pretty simple to get hold of a battery and test it or to ask the manufacturer. It would be much more advantageous to go with the one big one since I wouldn't need to balance the charges before connecting them and the BMS may not be happy with being connected to another pack. Edit: but that may be my only option since I need craftsman charger compatibility. I could probably go with a cheaper off brand but I don't want to risk getting cheese grade chinesium for a battery with such high power demand. ![]() Would I be able to get one big 5 Ah Dewalt battery 4 Ah Masione battery to do this or would it be best to get two smaller 2.5 or 3 Ah batteries and connect them in parallel? My intuition tells me the 5 Ah battery probably has a very similar current limit to the smaller ones since they're designed for the same tools. I know the 18650s alone can usually supply a higher amperage, but the BMS might prevent this. ![]() A drill battery would be the next best thing since a connector would be easy to design and they're comparatively cheap. It's a university engineering project for an intro level class, so that's understandable. Normally I'd go with a Li-po pack, but apparently those are off limits for fire hazard reasons. I need a battery to put out up to 18 amps for a few minutes and 14 amps continuously for the life of the battery.
