I've been using self-made chargers with Powerpack since the days of mav1 a long time ago.
The DJI battery supports surprisingly fast charging speeds. (130wh, mav 3 battery)
I don no other mav series battery, But Mav2 series(2 pro, 2 zoom)battery is perfactly charging just connect + and - pole.
And, it support superfast charging. (17.8v 7.5A DC Power supply, Force feeding!)
You can find these traces in my old post "Powerpack Build". (Sorry! Now I have'nt mav2. now...
Detail compare old and new
-----Old 2021-----
Cell = 18650 / 4S 20P
Weight = Max 9Kg
Capacity = Typ. 1000wh (Max 1050Wh)
Function = Only Quick charge for mavic II series.
QC usb(25W) x 2 ports & battery remaining gauge.
6 x Low power output 5.5mm DC connector.
Battery control = BMS...
Old my powerpack = 1Kw Power tank!! - By Grand Mavic Villain(GMV)
I was build complete my 1kwh powerpack in 2021.
But it have many problems, for example, limited functionality and weight.
Today's RC peripherals effectively support "more advanced and diverse functions" thanks to the rapid...
Yes, it just only can purchase in korea.
[email protected] : It is seller's e mail address
Ask if global sales and shipping are possible.
Ps : very expensive. 110,000KRW (About USD 95)

it is my mavic controller.
i'm using now tablet pc holder for bigger wide monitor.
Any size of 8 to 10 inches is compatible with any product you choose.
My device information :
Mavic 2 pro
Master airscrew prop(white and cyan)
---------------
On my experience, Master airscrew's prop is silent than genuine DJI.
DJI have large loud woo woo woo- Humming and sharpness windy sound.
Master airscrew product is buu- buu- buu low tone sound and quite...
Post two.
Finally, i can get the High performance LTC 3780 Board!
All capacitor changed garbage to "genuine panasonic polymer capacitor"
And, LM358 Opamp changed LM258 OP.
258 have a wide operating temperature than LM358.
And, changed the LTC3780 Main chip.
->Considering the possibility of a...
Post one.
Desolder garbage parts.
1. All of electrolytic Capacitors
-> they have Silver color generally.
2. LM358 opamp
-> it locate around blue color 504 potentiometer and R007 shunt resistor.
And other parts. (If you want)
I remove the
1. Capacitor
2. LM 358 OPA
3. LTC3780EG main...
The original LTC 3780(CC CV mode, blue color board) circuit, it have take a cheap garbage capacitor and low grade OP-AMP.
It cause very huge charging current error range, it mean Mavic battery is somtimes enter the "Over current protection mode" or "Slowly charging than original charger"
So...
It is my multiple use power tank.
Generally capacity : 1Kw(Typ)
- battery is have a nonlinear energy sections. this power tank capacity is just meanning that discharge benchmark result. (EBD-A20H)
Voltage : Generally 14.8v
Full charge voltage : 16.8v
Ampere rate : Mininum 68Ah.
It support
