What connectors for 8s?

[Hi8iS]

Hello, I just picked up a Joysway Silverline. It comes with a Leopard 5692 1050KV & a Hobbywig 130a HV ESC. I plan on running 8s & eventually want to try 10S. All my other stuff is set up to run 5.5mm bullets. Can I get away 5.5 bullets on this higher voltage setup? Or do I need to step up to 8mm connectors?

It really depends on the your current level, but based on the 130A limit of the controller you should be fine sticking with 5.5mm's.

Thanks for the help. Still very new to this & not trying to learn from my mistakes :). Another battery related question. My charger has 5.5 bullets on the end. If I do go with 8mm bullets is it ok to make an 8mm to 5.5mm adaptor to charge my packs? I'm guessing it doesn't matter as the y only charge at 10 amps.

That is fine, charging is low amperage and will not affect anything.

I figures that to be the case. Thanks again! Learning so much from this site!

Another question in regards to this setup. I have (4) 4s 4500mah 40 C Lipos. I plan on running two in series to achieve 8s. I know wiring in series doubles your voltage. But what about the C rating? WIll this double as well? How about if I ran all 4 packs? Two sets of 4s wired in series, then wired in parrallel to double my capacity & give me 9000mah for extra run time. Would this effect my C rating? Also is there a target mah one should try to achieve? Is 9000 to much? Can running on 8s for to long overheat things?

When you parallel batteries you theoretically double the C rating as the current draw is split between the two batteries. C rating is related to capacity so larger capacity cell can deliver more current for the same C rating.

As with any new set-up the best advise is to start with small props and short run times. Run for 2 minutes, bring the boat in and check the battery voltage and temperature. As a general rule of thumb you want to come in with 40% of battery capacity remaining and temps should be warm but not hot. Batteries should be between 100 and 120F, Controllers and motors should be below 130F.

Thanks again. All this is starting to make sense!
