Daly BMS Balancing

[Darren Orange]

Does anyone know where to get a female plug that would match up to the Daly BMS so you don't have to run all new leads to each cell.

Daly uses JST connectors, from what I've seen the XH style connectors. I've used JSTs in the lab, you need a crimper and pins to go along with the connectors. Check out youtube for some knowledge on why and how they work.

I dont want an active balancer because my BMS will do just a fine job IF I can enable balancing on it.

I'm not asking to balance below 3.4v, im asking to balance when at 3.5+ specifically. My battery spends 5+ hours a day at 100% (with some cells at 3.6v), while the BMS could be balancing entirely on its own and keeping the batteries at a nice 3.50-3.55v.

Right now I'm trying to push them up as close to 3.65v as possible to give the BMS more time to balance, but it just gets there too fast.

From my understanding the Daly only balances while charging. I own a dumb Daly and it seems to keep my cells perfectly balanced. Maybe you should try charging at lower amps.

Would something like this work with the right genders to parallel a Daly BMS and a Helco active balancer?

Yea that would be amazing! Just would need a 16S

I need this for 8s. I tried to find a parallel board but they are all 6s and the one wired above a "backwards".

I think it might come down to heat shink and soldering and recreate the picture above with the right genders.

This is what I came up with.. Saw it on Off Grid Garage (YouTube) and ordered from AliExpress.. Works great, all the parts and PCs. Were less than$20.. totally expected my BMS to suck b4 it was even bought.. Anyhow, hopefully this helps
