    found it sorry man
    "HobbyKing sells a parallel charging adapter that can parallel up to 6 batteries with power connectors and the balance connectors"

  • electric bikeelectric bike Club Members Posts: 42

    Okey i found the adapter i think, is it this one ? https://hobbyking.com/en_us/xt90-s-anti-spark-connector-2pairs-bag.html?wrh_pdp=7 i did also find one without antispark but my guess is that its better with antispark adapter :)@JanComputerman so u plug the batteries in to this one then in to the charger? Or do i need a diffrent adapter for that? like this? https://hobbyking.com/en_us/hobbyking-parallel-charging-board-for-6-packs-2-6s-xt-60.html

    You probably will not add a 3s10ah in series any time soon so get the bike running first and go faster later ...but short answer is you can balance charge the 3s in parallel with the 6s batteries but it will take even longer to charge all in parallel ...30ah at 2 to 4 amps rate? And you will need to deal with the connection issue at that time also.

    Turnigy P606 LiPoly/LiFe AC/DC Charger (US Plug) Does come with a board full of balance connectors see photo...this starts you off with all you need to charge the batteries and I recommend doing them one at a time so you see how each battery is functioning. The parallel charging board has been discontinued so you are limited to the one that comes with this charger or make your own cable with a 7 pin female for the charger wired to male 7 and 4 pin males for each battery as needed.

    so i have decided to buy 2 of these now https://hobbyking.com/en_us/multistar-high-capacity-10000mah-6s-12c-multi-rotor-lipo-pack-w-xt90.html and I just have some questions left, one of them is what adapters and things do i need to buy in order for it to charge both batteries at the same time. The other question is what adapter and cables do i need to connect the 2 batteries to the controller on the ebike? I also need to know how i can connect these rc batteries to each other and then in to the controller. Thanks for all the help with this project! @JanComputerman @WTWUK @Jason Phelan

    And @JanComputerman u talked about some thing u cna put on the batteris so i can see the current volts etc? can u tell me about them again and wiht links? thanks

    @electric bike.
    Been a bit distracted. Back now.

    Before we can answer that safely we really need to know what charger you are running?

    If we were to answer this question without knowing the charger type we risk our advice causing damage to your charger, batteries or worse.

    Cheers mate.

    iam thinking of the imax b6 and whats the diffrent between the copy and the orignal its like half the price, thanks. https://hobbyking.com/en_us/imax-b6-dc-charger-5a-50w-copy.html

  • electric bikeelectric bike Club Members Posts: 42

    it seems like its going to be these now..... https://hobbyking.com/en_us/multistar-high-capacity-8000mah-6s-12c-multi-rotor-lipo-pack-w-xt90.html

    The 10ah verison is not in stock or in sale :(

    Honesty I don't see much difference between these 4 button chargers.

    If you could afford to stretch your budget for your charger a little you will see an improvement in battery longevity.

    These new school chargers are well worth the extra money. Rather than using a small pocket calculator sized chipsets to utilise preset programs these new school chargers have a ARM processor and a simple operating system similar, but not nearly as complicated, as a mobile phone. On top of this the company that wrote the code for this product is a high end company that specializes in mission critical applications like medial equipment. ( http://isdt.com )

    https://hobbyking.com/en_us/isdt-q6-lite-200w-battery-charger.html

    The other advantage is a safer charge. Ever wondered why a smart phone doesn't need to be constantly supervised when charging and why fireproof bags arent needed? It's because current smart chargers run a simple set of charging programs while the new school ARM processor driven devices are dynamic and alter their chage cycle as the battery condition changes.

    If you can't streach you budget this far it's not the end of the world, or even remotely a problem. Just something I have recently learned and thought I'd put out there for your consideration.

    That sound advanced, i rather stay at the budget charger, But whats the diffrent between the imax copy and the non-copy one? And what do I need for it to work? 2 batteries 1 charger and how/what adapters/cables do I need to charge it and what cables/adapters do I need to connect it to the controller so the ebike runs? I really need to know now, iam planning in buying tomorrow..... (Friday 23nov) (please @JanComputerman @WTWUK help me out a bit here too.) Thanks all.> @Jason Phelan said:

    Differencecbetween the genuine and clone is quality of component and build quality, resulting in wider limits with the clones.

    To charge your batteries, you would charge in parallel using a parallel charging board, but finding one with XT90 connectors may be a problem
    However, with two 8000mAh packs charging at 1C requires 16Amps - far in excess of what an iMax B6 can supply, that being 5A from memory. It will take a long time to charge the batteries!

    No idea what you need to connect it to your bike as I have no idea what connections it has.

    Strongly suggest googling a bit where you will find myriad info on ebike builds and very similar setups with e-skateboard builds.

    i would like 6 hours charge time but maximum 8hours, can the cheap charger handle that time?'
    This picture is from the seller so it looks like this.

    how do i connect it from there?

  • electric bikeelectric bike Club Members Posts: 42

    so if i connect these, i can just plug the 2 batteries in and then into the Banana Plug Charge Lead Adapter and in to the charger and it should work?

    No. You will need to connect the balance leads as well so you need a parallel charging board. Like this:

    Discontinued here afaik, but easily found elsewhere...

    Okey ty. But how about the controller part? Now I know how to charge it but I don’t know how to connect the 2 batteries to the controller. Do I need adapters or anything? Picture above > @WTWUK said:

    @Jason Phelan @JanComputerman @WTWUK so I googled a bit about it so i need to change the battery cable from the controller to a xt-90 connector did i get it right?
    so i just cut the "3" and the "4" wire in theb picture above and cnoonect it to a xt-90 connector then in to the battery? should i have anti spark or just a normal xt90? if i need a antispark can i have one just on the controller and have a orginal on the batteries? or should i go antispark on both?

    Ty.

    Yes to soldering cables 3 and 4 into an XT90.

    You could use anti spark for every connection, but it is not strictly necessary - I use 12S packs without them on one of my helis and it is no big issue.

    Incidentally, what wire gauge are the battery wires on your controller unit?

  • JanComputermanJanComputerman Rhode IslandClub Members Posts: 173

    Hi I'm back ...been busy ordering during the big sale ... Unfortunately I did not see a lot of good deals on big 6s batteries but the 8ah ones you got should be great. Get the XT90 anti spark 2 pairs package and a XT90 series cable (2 into 1) and you take the female XT90 off the series adapter cable (has 2 male 1 female) and replace it with the XT90s female connector for the spark protection and then use one of the male XT90 connectors from the anti-spark package to replace the cheap plugs on the Controller red and black wires for power and you are good to go! Red is positive black is negative so be careful ...the XT90 connectors have them labeled. Make sure the Controller is turned off when you plug in the battery to the controller or you may over heat the surge resistor in the XT90s connector. And you don't want your bike taking off before you are on it!

  • JanComputermanJanComputerman Rhode IslandClub Members Posts: 173

    Just to be clear ... The XT90s female connector has the surge limiting resistor in it and you only need one on the series adapter cable that the controller male connector plugs into. You don't want to be changing the female connectors on the batteries mainly because the wires are hot all the time and there is no need to change them. Plug the series cable adapter into the two batteries first then plug in the Controller into the anti-spark connector on the series cable. There should be NO big sparking if everything is ok maybe just a little one or none at all. Be careful with the controller plug after you unplug it from the battery as it can still have 50 volts on it from the Controller capacitors for several days after being unplugged unless you discharge it by turning on the controller.
