Dji Fpv Drone Battery Mod.... It Can Be Done! 

I fix batteries for the mavic 2 pro, phantom 4 and the whole DJI line using software for chip activation.

@@joaovitorsantosgrigorio8133 how?

@@havasss use battery reading software and lipo charger to properly charge and unlock the chip via software.

What is the name of the software?

Lies - show proof, cuz ... No, no u didn't

I just got one of these. Did you ever embark on making the case? One idea I have is to make a case that can house 18650s kind of like a tv remote does, with cylindrical holes and contact pads to wire them up in series. It’d be alright because the drone draws max like 15A. Then, you could just charge/swap 18650s using a single battery frame all day

I found a guy who tries the same as you at the moment. I posted the link to the hackaday project but it was deleted. Maybe you should look for him by yourself. His name is AirCruiser.

was it from amazon? Lots of fake DJI batteries are sold there.

keep in mind that li ion and li po both have vastly different charge and discharge capabilities

Not worth the price. You can buy bms for cheap for batteries. But dji forces you to use their

They surely are not refurbishing bad batteries come on :)

Yes Looks pretty simple

Does it flash rapidly like 30 times???

I'm trying too. I have the program that triggers the chip. but I couldn't find where to solder the wires to reactivate

Easy to correct, when you disconnect the battery, use jumpers from another 6 battery and you can maintain voltage while disconnecting the main ones.

Don't forget you may loose the board in safety mode once it loses all power, Easy to correct, when you disconnect the battery, use jumpers from another 6 battery and you can maintain voltage while disconnecting the main ones.

Is this true?

Makes sense... it will think the battery is dying...So I have to keep it at 2000? Or can I go higher?

@@Bigballvlogs I am not sure. A few people have tried what you are doing without success. I was scared to try. Maybe the NewBeeDrone guys some how cracked the battery firmware also.. not sure. Keep us posted on your results.

Possibly. As long as you don't update you would be ok...

@@Bigballvlogs I will be following. Are there any FB groups your posting in?

I just got used batteries from Amazon that appeared to charge in full but the drone said it was critically low and wouldn’t fly. The new batteries I got had to do a software update. I’m very interested to see how changing these batteries would integrate with the main board.

Given flight dynamics you can shift COG depending on your how you fly. Middle of the road solutions work only for those that keep things middle of the road. COG and COT don't need to be in the same spot. In fact rear props usually have dirtier air when flying forward making them work harder even if COG is alighned. Trusting engineers is all fine and well if your priorities and constraints are the same as said engineers. If you look at how racers or freestylers build their drones you'll see that DJI FPV is underpowered, heavy, not well tuned not to mention easy to break and hard to repair compared to even BNF drones let alone custom ones. Hell even cinelifters put more emphasis on power to weight. I'm not saying DJI doesn't know how to make drones. Their props are quite efficient and their RTH functionality as well as video link are pretty great. But either their expertise doesn't translate well to more fun FPV or their sets of priorities are different. So trusting the engineers should go only so far. Some will want a bigger battery with less voltage sag and more flight time. Some will want to put smaller batteries sacrificing flight time for better flying experience. And even if you just match the stock weight and weight distribution you'll end up with ability to use top of the line LiPo's at fraction of the cost.
