Energy transfer active balance board

Post by Inwo » Jun 06 2018 11:18pm

The ones I have are 16s max.
36v-75v isolated input.
Maximum of 60v per board.

I tested down to 24v input. 12s lto should be ok with standard 16s board.
Measured >4a balance current. (Strobed)

Must be custom configured.
No limit string number using 60v sections. Global balance possible.


Ie. 3pcs 16s boards can balance 46s lto battery.
Or 48 if not worried about global balance

$200 delivered from and to conus.

Tell me more about this energy-sharing BMS, please?

E.g. Where to find spec sheet, price, programming instructions, etc.

I'm interested for a project with 36S LiFePO4.

Flying capacitor or active switchmode converters?
Does it include normal BMS functionality? (OV, UV, OC)

Yes, this is on the back burner.
I have to see what I have here, and what I have in them.
