- This is a quick guide on how to put together a 4 cell LI-on pack. That will double your power for half the weight! Here are a list of things you may need:
Wires (copper preferred)
Solder
Soldering Iron
Clear packing tape
4S Balance Plug (male)
Your connector (Tplug, Eflite, Deans, JST)
good info, back in the day when I had access to li-ion batteries I used to make my own packs but I did have a way to balance charge them,so they wouldn't last very long maybe 30-60 cycles, either way it was a lot cheaper than lipos at that time
I just salvaged 4 18650 from my laptop , I just want to know can use for my 250 quad
You're the man 🙌👍
which battery should i use?? protected NCR18650b battery or unprotected NCR18650b battery
how can u charge that batter pack..?what kind of balance charger u will use..?can u apload video for me tnx..nice job on your battery pack
jhayr soriano most rc chargers can charge them same as a lipo battery. If it the charger charges pb batterys, lipo, etc then it will charge in that charger for sure. just dont allow your pack to charge above or below the 4 cell setting.
thanks for simple n great tutorial
+athoxid anytime
Where did you get those batteries?
do you know how to make a 4s2p, 4s3p or 4s4p? And what the resulting capacity would be? Thanks
Zac Johnson Mah adds in parallel i.e. 2 3400mah in parallel would result into 6800mah.
Also no changes to mah if batteries connected in series so 4s(4batteries in series) will have same 3400mah but 4s2p(2 4series batteries in parallel) will have 6800mah.
In short mah adds in parallel (no change in series) and volts adds in series(no change in parallel).
Won't the heat from soldering damage the battery?
hi sir thank for the video
How to scuf ther terminal.. u used what tools?
a dremel
simple, short and sweet, thanks.
I'm gonna order some in a min, what is the minimum voltage you can run these at? I understand you can go lower than a li-po. For example, my low voltage alarm is set to 3.5x3 (10.5) on my apm2.6
I am not sure I limited mine with a timer. I tested all my stuff real time. Example: 45 minutes for my long range plane with apm and lights.
nice vid!
Where is the black wire from balance cable connected?
On the negative end on the direct other side of the positive. (far battery)
so how would i solder it to increase the capacity but still keeping it as a 4s battery
By adding cells in parallel.
Hello, I have a question, I need to buy 3 other 18650 cells, and i'm sticking between this two model, the LG HG2 for 3000 mAh at 20A and the LG HE2 2500 mAh at 35a, which is the better ? This is for a ZMR 250 with 2204 motor.
Thanks.
Martin Thibodeau im not sure, I only use these packs with my rc plane. it doesnt need much voltage. my tricopter wouldnt fly with these for long because the discharge rate is 3c. i always pull more than 3c with multirotors.
Martin Thibodeau -more amps more better but seriously the 35 amp and make sure that this is not stated Burst amp or pulse amp these battery’s are almost 50g each keep that in mind
Difficult to say, but it looks as if you're using PCB protected cells. Can you clarify?
Shadowcruise99 18650's are all pcb batteries unfortunately. gotta be careful with the charge.
Hi, how many amp can this pack handle? For an rc plane.
+Dennis rc 1c per cell they will be happy ... theres a better cell now 18650GA
Very true
hello can you help me please.
i make 3S batery with 18650 six batery but the result 16V not 11v . can you helpme draw diagram for me. thanks
Minimum 4.8 volts per cell or or 14.8 guys
FPV Flight Airborne unki charge kaise kre ge 4 laptop vali battery ko Jo ap Ne nanai hai jaldi batai ye
aaj he 6:00 bje tak
can i use this battery pack with my quadcopter?
Mayank Agrawal yes but it won’t fly long
lipo cheaper ! more voltage and more power.
Lipo has way less energy density. Pretty important parameter for a UAV.
Really BAD solder.
