Russian site doesnā€™t charge 20% VAT, since it is intended only for non-European shipping addresses

600 cells were ordered from nkon, still waiting shipping info. best guess itā€™ll arrive in two weeks from now.

I had looked at charge only BMS

64

Thereā€™s a ton on eBay, any small 10s bms will do, just look for charge current to be 2-5A

Get the bms from besttech for charge only in bulk you get a good price

doing a bit of organizing here, i wrote down names of everyone interested and quantities theyā€™re going after.

iā€™m going to markup the cells a little bit to cover financing costs, itā€™ll be $3.50 a cell (thatā€™s still $0.75 less than buying retail and a 7% markup on my part).

if that makes you angry, we can internet fight about it here.

take a look and edit accordingly, please:

also got a quote for charge only bms from bestech, itā€™s basically $20 plus fees and shipping so probably about $25 all in:

Okay, was planning to build a 12s5p and maybe 12s2p as well

what BMS would be best suitable with these Q30 cells for a 10s4P battery?

generally speaking, the two most popular brands are bestech and supower.

you can get a lower discharge bms on the cheap if you intend to bypass discharge and use it for charge only.

otherwise the bestech PCM-D223V1 is a popular choice:

and also the supower modules:
