A few years ago i posted a video in YouTube how my DJI Ronin works with LIPO battery. There many people askin in comments to explain how i did that. So let’s see how to make it step by step.
IMPORTANT! YOU CAN DO THIS ONLY WITH DJI RONIN BATTERY 1ST GENERATION 3400MAH, IF YOU DISCONNECT POWER FROM DJI RONIN 4359MAH OR FROM RONIN M/MX BATTERY – CPU WILL BE BLOCKED AND REQUIRE RE-FLASHING
First of all you need to open your DJI Ronin battery and carefully remove all 4 cells, which are dead probably.
You need to buy Lipo 4S balance extender cable, it cost maximum few dollars in HobbyKing for example
You will use that female connector to connect your Ronin with Lipo battery balance port
So after you disassembled Ronin battery and removed original Lipo cells your battery electronics will look like that
Here the diagram of DJI Ronin battery board and my recommendation to pins where to soldering balancer cable
Be careful with polarity, before starting battery electronics make sure to check everything with a multimeter
Glad to note that it was in 2019 and was a temporary super simple mod, not really really hack, just let’s say its a way to supply DJI Ronin battery board with external Lipo cells.
For now i using a more useful thing, like a camera dummy adapter, using for DJI Ronin, where your gimbal is powered from VMount battery using a standard DTAP plug, here are some photos of the prototype, its amazing and already works well many hours on set. If you’re based here in Thailand you also can rent this dummy for your shooting following this link https://rental.filmservice.asia/shop/steadicam-easyrig-movi-ronin-thailand/dtap-dummy-for-dji-ronin-dji-roninm
If you are interesting to rehouse your DJI Ronin battery to VMOUNT DUMMY please can contact me directly to Whatsapp +66830029127
IMPORTANT! YOU CAN DO THIS ONLY WITH DJI RONIN BATTERY 1ST GENERATION (3400MAH)
My fees for replacement DJI RONIN electronics to DTAP dummy 100$ (incl.parts), normally it will take one day to converting your battery to DTAP dummy + shipping to/from Bangkok, Thailand.
Here important update. Before sending your boards let’s check together which version of DJI battery you have.
For the moment of start writing this article, i didn’t have idea that there were different boards inside DJI Ronin batteries. Here are the photos:
So with DJI Ronin first generation 3400mAh battery all works, already tested well with different Ronin1 heads and all perfect. But many people have that 4360mAh or DJI Ronin M/MX 1580mAh wich arepain for the ass.
I already recieved DJI RoninM from US and 2x 4360mAh from France and they are still bricked.
In case you also got bricked Ronin 4360mAh or Ronin M/MX 1580mAh battery here is a way to return it to life. After open the battery box you can connect cells to charger like Imax or Turnigy directly. After balancing cells with an external charger (or in case cells cant be balanced they can be replaced to another brand new lipo battery) then require to clean errors (reflash CPU). This procedure requiring EV2300 programer and commercial UBRT soft which are not cheap. Then one problem (i can’t still find a way how to cheat CPU on that newest 4360mAh or DJI Ronin M/MX 1580mAh), so in case we make mod like i show on the beginning of the article – then after replacing LIPO from balancer – you have brick again (( and should reflash cpu again.. So the easiest way just return brick to the life as normal RONIN Battery (no mod and no dummy). Or maybe later i can try to build LIon mod from that boards, should be also cool as an option.
Thanks for reading,
