Let me know if you see any problems with this wiring diagram. I am very new to this but I figured I would try to draw something up as a starting point. Is it correct to run the batteries in parallel first and then series or does this not matter?
Do I need a banana plug in the first diagram or could I just cut it out and plug the top black wire directly from the top xt60 to the bottom xt60?
The batteries look cool however, they are only 15c which is low for a 4000mah battery.
Of course running them in parallel will help making them effectively 8000mah and capable of 120a continuous.
The problem with the charging diagram is that you’ll be charging in parallel and doing that can be a bloody nightmare.
I would not recommend charging lipos in parallel under any circumstance. It would be safer to charge each pack separately. Every lipo cell will have a different internal resistance so even in a single pack the cells will not discharge and charge at exactly the same rate. This is why they have to be balance charged. Trying to balance charge in parallel just defeats the purpose because the charger you mentioned can only balance up to 6 cells at a time. in order to parallel charge, all cells would need to be perfectly matched in terms of internal resistance and would need to be pre-balanced before charging. This is just not going to happen. your either going to under charge some cells or overcharge some which can be very dangerous.
If the charger can only balance 6 cells at a time would it even work to charge one of these batteries? They are 5s2p batteries which means 10 total cells.
These batteries are also already in parallel so would they charge unevenly for the same reason even if I am only charging one of them at a time?
I want to wire 4 3S LiPo’s together. 2 in series 2 in parallel. Don’t want to have to take the batteries out of the box and plug them into a balance board whenever I need to charge. Anyone have a diagram on how I’d wire that? Including balance leads
