Small Charge 10s BMS

Hey, everyone, I’m looking for a small and reliable charge BMS, it seems nobody ever posts what BMS they use

Oh and in small I mean smaller than the Bestech d140, and before you tell me to use the search function I did!

Im looking for a bms with really slim width.

Even bigger than the one indian gummy posted, ive seen smaller bms but they dont balance the cells

If that balances the cells it would be great. Trying to find out if it does.

im pretty sure that doesn’t balance cells image

Seems baxter found one

in desc it states “and balance charging functions”

gonna buy one and see how long it lasts

There’s a perfect gap on the Spud for a small bms IMG_20190119_231618

dont trust that. find the model number and check the data sheets. it seems if you want to go down to that from factor and still keep balance capability you will have to solder balance boards.

That gap is literally the size of a pencil…you’re gonna get a PCB with those switches and balance plugs in there?

Thats why im not gonna install the bms in the batt pack but out in the open so i can alawys monitor indivudal cell voltages, plus it uses 11 pin leads so it should fit most other bms, and the 75a discharge the bms clams is totally a sham

@ZachTetra trust me, i always make it fit :sunglasses:

If you say so, I’ll believe it :laughing:

Now my question is how to wire the balance leads lol.

im guessing the first read wire is for batt 1 positive and the 9 other white wires in order, and the black wire connected to batt negative?

yep 10char

I have a better option for a complete enclosed bms (direct discharge) D127 for 12s and 10s D124 10s only

Both we have tested and use in our builds


D127 14%20AM 37%20AM

How about the Neptune 15?

Endless sphere says it’s reliable, and it’s tiny as hell

Aaaaand we need an opinion from someone on this forum :wink:
