Dayton Audio's LBB-3 compact battery holder board delivers high current portable power to small amplifiers, 50W amp boards, or other 12 VDC projects by combing the voltage from three 18650 Li-Ion batteries (sold separately). It's small enough to fit inside a portable speaker and has multiple 12 VDC outputs to power an amp, tone control, Bluetooth, and other preamp component boards. Enjoy the extended listing time you get from Li-Ion batteries on a single charge. 18650 Li-Ion batteries come in a variety of amperages, and to get the longest playtime from a 50W amplifier or amp board use at least 2600mAh batteries.
There is no need to remove the batteries from the holder because the Dayton Audio LBB-3 has a built-in charge circuit. Just plug in a power supply and the over/under charge circuit prevents correctly installed batteries from overcharging and fully discharging, shortening their life. The LBB-3 battery board needs a 15 to 24 VDC power supply (sold separately) to start the charging process and to start its output power. This enables you to listen to music while the batteries are charging with this amazing battery holder. To view charging and battery status press the push button on the battery board, or use Dayton Audio's LLB-LED push button and LED kit to view status externally. If you remove a battery, the power supply must be plugged into the holder for the battery board to start working again when the battery or batteries are reinstalled. The polarity of the batteries must match the polarity of the battery holder to prevent damage.

Can you increase the voltage to 24 volt by hooking up 2 in a certain way
The battery pack says it is half charged but when I try to turn on the Dayton amp board it doesn’t work unless it’s always plugged into the wall
Great idea ! Now all that's needed is to come out with a way to run multiple packs in parallel for more capacity and a four cell version.
Each battery board comes with a little cable. If you are only utilizing one battery board with your project the cable would connect your battery board to your amp board. If you want to add another battery board just use the supplied cable that comes with the new battery board to connect to the existing battery board. There are 3 identical connection points, just use one of the open ones on the first battery board.
using this board, is there a way to reach 24vdc(or really close) for a long lasting portable bluetooth speaker set up. can they be linked together to reach my goal?
@@PartsExpressOfficial To clarify - I would need to buy another battery board to add to the first one? I couldn't somehow connect just a battery holder with leads to the first board? Thanks!
@@alexmurray116 You would need another board for proper charge/discharge, overcharge/over-discharge protection; as well as maintaining proper balance between the cells.
I have the kab BE board how do I charge it
Is there any way to connect 2 of these in series to make a 24v power supply? A video on that would be great!
Update: After searching around online I found that there is a similar board that takes 5 26650 batteries to produce a nominal 18.5 volts. Unfortunately Parts Express doesn't sell it, but you can find it online if you search for "BCPB4". And it looks like it will take the same function cables that PE sells if you want LED indicators, and best of all the 26650 batteries have nearly double the life of the 18650 batteries! PE really should sell this part since their Blaster Box kit is screaming for the extra power it provides.
SSHitMan where did you find it? Can you post a link?
Can I use the KAB-BE board with the LBB-3 in parallel with the included cable for longer play time?
Yes, but the boards would have to be charged separately.
I purchased the MK Blastbox and am interested in adding another of these boards to increase voltage from 12v to 24v, however I am not an electronics wiz and the instructions just say that "you can add another lbb using just a few diodes" what kind of diodes do I need, and what does the wiring diagram look like?
You should just contact one of our techs! They can answer your questions.

Parts Express+ You can take 4 18650 cells and weld them up in a row 3 times, make sure they're sturdy and you'll have a 4P 3S - 12 batteries, Right?
How can i hook up 2 or more
i just picked up the LBB board for my next project and after checking it out and hooking it up i have a few questions.
1. what type of connector is J2 and J3? it looks like some type of press to fit connector for bare wire but before i start jamming wire in there i wanted to know for sure.
2. in between the J2 and J3 connectors there are 4 unfilled through holes. using my DMM i get readings of 12v, 8v, and 4v . i assume the it has something to do with the voltage of each cell. what is the purpose of these holes, if any?
3. what is the function of the J3 connector? the documentation says "15 to 24 volt input" . is it for hard wiring the power input in place of the barrel jack?
1. J3 / 4, those are both for bare wire. Solid conductor works best but you can use stranded wire, it helps to tin the conductors first if you are utilizing stranded wire.
2. The terminals between j3/4 are there simply as a test point.
3. J4 is input J3 is output. J4 is the same as J5, just for bare wire.
4. See wiring guide for clarification of terminal numbering. www.parts-express.com/pedocs/more-info/325-200--dayton-audio-lbb-3-quick-start-wiring-guide.pdf
ok. cool. thxs for the fast reply.
hi there! any significant differences between this board and KAB-BE 18650 Battery Extension Board?
Long story short, use the KAB-BE for KAB boards.....use this board for anything else.
Parts Express How can i hook up 2 or more
@@PartsExpressOfficial the JAB wondom board looks identical to the KAB-BE, can i use it in the same way with the KAB-160 board?
I bought this for my Dayton amp board and it won’t charge or put power to the board but when I plug my speaker in it works but the battery’s dont
Which battery board did you buy and what power supply are you using?
Parts Express I bought the one in this video and I’m using a and I’m using the dc charger that gets hooked up to the amp board and it doesn’t charge the battery pack
How do you chare the board
There is a cable which feeds to a power connector. you can install that on the outside of your project and plug in power there.
@@PartsExpressOfficial thank you
How can i hook up 2 or more
You can simply just plug them into each other.
Parts Express thx
@@darksbacon5856 No problem!
The battery pack says it is half charged but when I try to turn on the Dayton amp board it doesn’t work unless it’s always plugged into the wall
Most likely one of the batteries isn't charged. Charge each one separately, then check them with a multimeter, then try them together again.
