Who makes the LS IMR-18650BB cells? What do we know about them? Id guess theyre made in China. IMR signifies lithium manganese oxide cells (LiMn2O4). This is a good power chemistry - it trades off energy storage (mAh) for output amps. In general, you can pick where you want to sit between them, but something like a super high energy capacity cell (3400mAh) will sag badly and generally not like you pulling 30A off it. A power cell may only store 1500mAh, but will do 25-30A all day long and not care. Yes, thats an awful lot out of a little battery. Yes, modern power cells can do it. rev2023.5.1.43405. I have been around both types when they get shorted, trust me, it's ugly when a big LiPo gets shorted but these Li-Ion typically just stop working and sometimes bloat up like the infamous Apple Laptop battery bloat.

Out comes my Tool Battery Internal Resistance Tester. This is a ZB206+ tester, wired up for poking the ends of tool battery cells. I have a few of these laying around in various configurations, and this one stays wired up like this because its useful, often enough. Full four wire interface, so I have accurate sag information, and its accurate enough for comparisons. Wow, they both really kick butt, my previous e drill was an old nicad 12 volt. Unlike the DeWalt 12V battery, the Ryobi labels the negative and positive terminals. Unlike the newer DeWalt batteries, the rest of them are a mystery, at least from the outside. I did a bit of probing from the outside, but its sometimes easier to figure it out from the inside. The main power connectors here are a single hunk of metal instead of the dual finger DeWalt style. Ive no idea which is better in theory, though in actual use I doubt it matters at all (especially for lower power packs like these). I'm working on a project that will require a 60V DC (mobile) power source. The cordless configurator makes it easy: tool bodies, batteries, chargers, lights, lasers, vacuums, etc. DCB201 has a 2-year limited warranty. 4.4 (31) $7599 ($19.00/Count) Save 5% with coupon. Forum contains no unread posts DeWalt DCB120 Battery Pack(about $25 on eBay for a genuine one)is a Type 1 battery pack (the 20V Max packs are Type 2), rated for 12V (Max), and 15.6Wh. Ive messed with enough DeWalt packs to know that their capacity ratings are determined by someone in marketing with a calculator and not any of the engineers. If you divide 15.6 by 12, you get a neat and tidy 1.3 - so Id guess the cells in here are 1300mAh cells, and three of them. Now, if I were to call this pack something, Id call it something like 11.1V, 14.4Wh, but thats me. I will nevermanage to get myself hired as a tool battery marketing type. Flipping the board over, weve got a little thermistor in the top left corner, a UP72 UCHIYA thermal fuse (configured for 70C), and a big diode going from the negative plane to the positive plane. My guess is that this handles reverse polarity connection - if you were to try and hook up a charger backwards, this diode would short out your charger, at least after the battery bank drained through it. Its the type of thing that Im sure exists for a reason, but I cant figure out where it would reasonably be used. If you tried to force current through the pack backwards, youd drain the pack down to the low voltage cutoff (fine), and then when the transistor closed, youd end up dumping current through the diode. Its a weird feature, but here it is. It shouldnt do anything in normal operation, but if you happen to know whythey have this, Id love to hear about it! Cordless Impact Wrench (Tool Only), XTREME 12V MAX* Brushless 3/8 in. Besides the positive and negative posts there are six smaller pins labeled.

Up to 80% battery yields overnight. You've done some impressive work researching your battery packs, but it was unnecessary. 12V MAX* COMPATIBILITY I really like what DeWalt has done with their battery packs. Theyve moved all the smarts off the pack and into the tools, allowing them to have a pack that is literally cells in a case with a dumb interface board. Its a great way to build a battery for tool use, because theres nothing extra in there. The Ryobi pack is a good pack, but the BMS in there is wasteful. The tool can handle the low voltage cutoff, the charger can handle the high voltage cutoff, and the whole circuit board, in the common case, will be trashed when the pack is thrown out. Yes, it grants a tiny extra bit of safety if something goes wrong, but theres no reason you cant have a backup overvoltage detection system in a charger (and refuse to start charging if the voltage is too low). Most of it is just extra complexity, and extra things to go wrong. I dont see the value in that system, unless, of course, youre Wan Nien, convincing tool makers that they all need your battery management boards and battery packs. Not a bad spot to be, really. The Ryobi 12V battery(about $45 on eBay, for reasons well see soon) is much the same as the DeWalt, at least as far as specs go. Its 14Wh instead of 15.6Wh, but thats just as likely to be due to differences in creative math as to be actual capacity differences. Not a member? Make sure you know the direction of current flow.
