10s2p connections

[srislash]

how does this look.

I notice the blacks are short at the T junction. Can the red ones be made to match and still have the batteries reach?

I would install cap bank(s) in over the motor collet.

no, that's as short as i can make the pos. if i run cap bank, i will put where the strap is. if i put it over the flex coupler, where would i attach the cap bank?

Any where on the wire. Just strip a bit of insulation and solder. But you would have to uber careful so it can't hit the coupler

You can extend the black wires at the T so that they are the same length as the red. The cap bank can also be wired in at the T's to make things simpler I think.

does the cap bank need to be after the 2 wires are joined down to one wire? or can I put it on one of the double wires?

Oh yeah, you still have the two leads off the ESC. Well unless you can make a cap bank for each set of wires( I make my own for this), up top is the best option.

So I came across this thread because I need to wire up an 8s2p (4-4s1p packs). I'm struggling to visualize how I should do this. While I understand the concept of series and parallel wiring, I'm not sure of the best way to do this (least wire, convenience, etc.).

Could perhaps a centralized board be made that allows the batteries to simply be connected to corresponding jacks on the board and then the board has the correct wiring to setup the serial and parallel connections? Or is it better to just do it in some wiring harness? Does anyone have a nice diagram showing an optimal way to make this harness or a potential board?

The specific wiring used is hinged closely to the layout in the boat. It's really hard to know without seeing pics of the layout, at least for me...

[Pennstater]

I don't have any pics handy, but I can try and describe it...

The boat is a 48" Warehouse Hobbies Enforcer; deep vee. Standard 5" rails with motor mount in center vee. ESC is mounted above the motor (a CC 2028 Extreme with an OSE mount). The batteries would be on the outside of the 5" rails.

In this configuration, I would assume two batteries would go end to end on each side. Just thinking "out loud" while I type this: There might be enough room to turn the batteries on their short side ( instead of laying flat with label up they could go on their sides with the label facing in towards the center of the vee or out towards the sides), that way they could be set side by side instead of end to end.

I use a length of 8gauge wire and solder the necessary bullets to that. Like Craig said it does kind of depend on the layout of the boat. My example is with ESC's on either side of boat, I use 8mm bullets from ESC to 8G wire across to other ESC 8mm bullets. I then solder 6.5mm bullets(my preference) along the connecting wires. I have one boat with a 8s2p setup and another with 6s4p. Cap banks attach as near to ESC board as possible.
I do have another setup with central ESC's and they are connected using ESC supplied wire and a short jumper giving a 4s2p supply. I can get you pics of the above setups

Ok it is even easier then, all you really need is a three way connection for red and same for black.
For this may I ask what size connectors you are using on the batteries?

[CraigP]

Yes, sounds straight forward... I like to put the two batteries on each side with the wires facing each other, so I can Tee off from there, go straight across to the ESC and the cross-over to the other side. I was talking about getting your wires as short as possible. To that, the CG and battery placement needs to be worked out already. If you still need to move the batts around, then you'll have the make the wires longer. Most batts have #10 wire coming out. So I would make a plug for each of the batteries with #10 wires coming out of those, then join the two reds and blacks into single #8 wire. This #8 wire is your cross over wire to the other battery pairs which has the same #8 to #10 wiring as the other side on the opposite side and a power feed to the ESC. Try to make each side as identical as you can.

[Pennstater]

Thanks for the replies. I'll need to re-read this to make sense of it. Any diagrams would be helpful (I may draw up what I think it should be and post here for verification).

I use 8awg wire with 6mm bullets. FWIW: the CC 2028 Extreme is 800kv and the ESC is a SF 240HV Pro (2, I think).

[srislash]

Oh yeah, on a larger boat shunt wires are likely necessary. My configs in this manner have been smaller boats and I have made little blocks out of connectors. On a smaller boat the battery leads are able to meet in a common place from each side

Does this look right?
