for 14.8 Volts you need 4S i think
8. Multistar High Capacity 5200mAh 4S 10C Multi-Rotor Lipo Pack
475 g
5200 mAh
10 c
should do fine

Yes, they are 4s. The cells have been successfully replaced with a Tattu 5200 pack. It was as easy as we all could have hoped. Simply solder in the power leads and balance taps where they were taken off the original. The process was well documented on a popular social media site recently.
We could really use someone with 3d drafting skill to come up with a 3d printable case now. Removal of the old cells is pretty destructive. I'm getting there with drafting for prints but I'm sure a decent designer could whip a design out in no time.
Here's a link to the Tattu pack,

I have high regard for Tattu products. We run them mercilessly in FPV racing and they really hold up well.

has anyone "built" a battery for Solo using Li-ion batteries? you should be able to use 12x 3500mAh cells for a 4s3p 10500mAh battery weighing only 100-150gr more than the stock 5200mAh stock solo battery... should be getting you around 25-30 min flight time with the gimbal...
Super late to the party here, actually just disassembled a pack tonight. The Chinese printed batteries have welded case halves, disassembling those needs to be destructive. However, if you're careful about it, you can snap the halves back together. I can snap more photos of the boards if necessary. The cells are getting recycled asap, cell 0 is inflated, which explains why the battery didn't work. It came with a solo kit I ordered last month, 3DR kindly replaced it.
Use the Tattu 5200's. The multistars above work, but are a bit too long to fit if you put the top half of the cover back on - or at least that seems to be the case after my rather destructive dissembly

Will definitely give that a shot! Thanks for the tip! On that note, does anyone have the cad drawing of the battery case by chance? seems 3DR blocked off their google drive page.
Got a Solo without chargers. Wasn't a big deal, just done an adapter from XT60 with 2 pcb pieces to fit into battery pack. And charged from a regular LiPo charger, but put on NiMH, 16,80 V , 6,00 A. works like charm !!!
After, was curious to find out if battery cand be excanged, without loosind time of charging same battery (i have only 1 pack, so charging it often will loose it soon)
So, here are some pictures from my battery pack dissasambled. Tace care, is destructive, because case is glued in some spots and also take care not to punch LiPo cells.
Next will be moving battery electroniscs inside drone, to keep telemetry, and outside will have onlu main plug, XT60 and a ballance plug.

simple question: why does the battery need to be in the 3DR form factor? Velcro would work just as well, as it does for every airplane I've ever flown:
I'm looking for an simple replacement, simple soldering for the SOLO to maintain voltage monitoring.
As simple as a XT60 off the shelf battery.

I plan to do something similar myself, along the lines of how most drones work now, so i dont have to use a proprietary battery. I have an idea in my mind, ive been studying the solo nonstop for the last 2 weeks and im sure i can find an answer to this problem. I will document and share any info i come up with, also if anyone has a bad battery or 2 they would like to get off their hands please send me a message. I dont have much $ but im willing to put time into finding an answer for everyone.
If using same battery specs and connect balance plug also, yes, it works. But if want to use a larger capacity battery, is needed some software intervention into battery controller. Found in another topic comunication protocol and might be a way to emulate Volt-Amp controller by using a small Arduino Nano.
I'm at the dis-assembled stage, ordering the tatu battery. My old batteries don't work more than 2 minutes in cold weather now.
the original battery case is pretty much toast, afer dis-assembly and would like finished product to be able to snap in and out like original model battery, anyone ever solve that part of the challenge yet? I'm not interested in exotic charging, schemes, I want a drone that flys as it should and doesn't look like a frankendrone. I'm not knocking those efforts, but I need something that looks and works professionally, and if this effort fails I guess it's time to get a Mavic Air.

You mean buy the cells individually? and connect them in series, and bring out the balancing leads etc? The Tattu batt, looks like the right voltage, amp hours and current capacity as well as right size, and we've got at least one yes vote from a user of their products already. So no need to reinvent the wheel, alls that is left unresolved in this discussion is repackaging them.
