Another New (?) Lithium Conversion w/ Master BMS from Yesa

@mudder might know something. I wouldn't trust any msg's word without proof

 

Well that's what they all try and convey but seemingly this is very problematic . It has a battery in it an HV battery . No matter it's voltage and Killowatts and all that . Building a battery takes some doing . Or more doing than being done . Not sure .

 

I haven't reviewed this product. I will review it if/when someone sends me one.

My recommendation is to ask the manufacturer if it has a per-cell BMS with supervisory control.

 

I can imagine in the reply you're going to get in my head too.

 

They are clearly attacking the last company who tried to retrofit lithium in place of niMh. Primarily stating the Toyota bms will overcharge aftermarket lithium modules and create reliability and safety issues.

The marketing shows their new "master bms" measuring from one end of the assembly to the other end.


The facebook "file" description states "It monitors pack voltage/current in real-time and intervenes (e.g., disconnecting or limiting) to prevent the vehicle's charger from pushing lithium cells beyond safe limits".

The "Master BMS" mounts on top of the modules with thermal paste between.

Nothing references individual module or cell monitoring.

 

Sounds great to me and it's real easy to type that crap out on a computer and print it actually making it happen in your car you're trying to drive has been elusive the whole life of the model 20 years close enuff to it . And for the prices they want to charge for me to be the guinea pig no thank you I'll continue on with the nickel ..
