Looking for a 140A BMS within certain measurements

Am looking for a BMS that can output 140A (peaks, for an ebike) that doesn't exceed 130x135mm (thickness doesn't matter).
Have looked all over

Speedict Neptune 14 or 20?

Wow, looked all over google and also their official website and zero information about bms specs, nada, just blubbering about ground breaking ideas (which are just common features of any bms) and price their tiny (can't be high current) 20S at 188usd

Their website is a bit strange- try a different browser?

Specs at https://www.speedict.com/tech-specs

For the 20s- Max. Discharge Current
250 A (Rated) 280 A (Peak)

There’s a thread here by the owner of speedict

Yea they are a bit pricey but they stand behind the product. No affiliation I just use a couple of them.

It doesn't seem like they know what they are doing.
Look at the question above and what he answered.

It's from 2015 and nothing is clear about them.
They talk about how they don't know much about batteries and building their product from customers feedback which seems really unsafe for anything related to batteries.

Plus, it's too small for their power rating and I guess they just take the current rating of the mosfets with zero thought of heat dissipation and declare that this tiny BMS can do 250A.
All of that "promissing" package for "just" 188usd :lol:
