Tattu 10000 mAh smoked the power module


#1

I bought 2 Tattu 10000 mAh batteries (from unmannedtechshop) and a power module from ebay ( http://www.ebay.co.uk/itm/291272159858?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT )
I connected the power module to the Navio2, and to one of the batteries: the power module smoked … Before connecting it I made sure which end goes to the battery so that everything looked good…
What did I do wrong? Thanks

It looks like I plugged the wrong end of the power module to the battery according to this: https://docs.emlid.com/navio/Navio-APM/img/NavioPlus-PowerModule.jpg

But in this video the guy is doing the other way round which is the right way: https://www.youtube.com/watch?v=uVGo2VBjpUc

Sorry to hear about that, I am not sure about which PM you purchased but some only support up to 4S Lipo. Only the high voltage ones support 6S batteries.

It seems to me as per the description it supports my batteries

Features:
XT60 Plug.
Max input voltage: 30V.
Max current sensing: 90A.
Voltage and current measurement configured for 5V ADC.
Switching regulator outputs 5.3V and 3A max.
6P molex cable plugs directly to APM/Arduflyer 2.5’s ‘PM’ connector.

The problem could’ve been I connected the battery to the wrong end …

I’m waiting for the UnmannedTech’s PM to become available again … :wink:

Sorry to hear about that, but atleast you had the problem on the ground instead of in the air, causing more damage! We have just received more stock of our power modules btw :slight_smile: We will also be getting some new ones in a few weeks that will support higher current too.

Thanks for the reminder, I bought one yesterday already from your shop! :wink:
