i just got a 2.6 mtr glider  and the suggested battery combo is- 3s 5000mah or 6000mah.
i have few 2200mah( 3s) and a 1500 mah battery>
i thought of connecting 3, 2200mah batteries in paraller but i have got only 2 2200mah batteries left for this glider ( planning to use other batteries for other uses), so i wanted to know if i could connect 2X2200 and 1X1500 mah batteries in parallel , if yes just tell me how !!
i have connected batteries in parallel (same mah rating) but confused with 1500 and 2200!!

logically there is no problem attaching them in parallel,

i mean 2.2A+2.2A+1.5A but even if you do it 2.2A+2.2A then only difference will be less flight time,

so in my opinion you can go with either ways.

thanks sir but i want all d 3 in parallel and i read tat i should connect the charging leads also in parallel!! i dont know if its true??

One more point to consider apart from the current is discharge rate or C  rating....  All should have the same  discharge rate...

you can leave the balancing ports alone.

Wouldnt the smaller capacity one drains faster and will get charged from a higher capacity one and the final efficiency will be much lesser than using a single high capacity lipo or similar capacity in parallel?

For my raven clone(Scratchbuilt a day ago) i have to use two 2200mah 3S lipo in parallel to get CG balanced. just run it for once today and seems like the cells are at different level. some at 4V and some at 2.9V. lucky to know that im not alone. Coincidentally i have 2x2200mah in parallel and a little more run could have killed the weaker cell sooner..!! those are turnigy 25C Lipos and used for less than 3 flights.

Look at this for a quick parallel connector option:

Wont go into lipo details i see senior members already helping you.
