Does this mtn driver support 2 batteries in serial?

[trailhunter]

I want to do an xhp70.2 build in a convoy L2, would this driver support 2 batts FET + 7135 Driver - 20mm - MTN-20DDm ?

It won’t work as is. The problem with 2S+ input voltage, is the MCU. The zener diode limits the voltage to the MCU in order to protect it. This driver doesn’t have one, nor is it a listed option. But, if you can get in touch with RMM (I’ve read a lot lately that he’s very busy and hard to reach) you might be able to get him to add a zener diode for an extra charge.

Alternatively, you could buy a 20mm driver from Lexel, who does have a 20mm 2S driver option and also offers popular BLF driver firmwares.

First time hearing of lexel, thanks for this recommendation.

This is the one you need —-pick Zener mod and if you want low voltage protection

FET Driver - 20mm

Thx! Ordered a couple
