18S BMS? what do you all reco?

Got a fun bike project in the works and need reco’s on 18S BMS’s Please lmk which you guys like/recommended. All the werid voltages quoted on HV BMS’s is throwing me off.

For example:

Is this a 21S BMS or a 18S BMS? says it goes to 75.6V (18s) but then the title says 21s…

Cell and enclosure mock pics for fun:

yeah man i’ll take it just trying figure out whats available/best for the price

I like Daly’s they’re good bms’s especially for the size and price. But they do not have the balance current to keep a pack of that size maintained. 4P is my cutoff, after that I go smart BMS for the static balance and to be able to monitor with that lovely Bluetooth app, so I would advise the same. Alternatively, you could try one of those expensive balancer boxes that are balancing in amps not mA.

bit of a BMS noob never sourced them myself, links would really help me!

I haven’t actually used one of these balancer boards myself, so I don’t know how well they work, but they were introduced to me by @Scepterr

As for the smart bms, LLT is the go to. Tho I do believe the higher voltage ones are quite large.
