Thanks DanielArnett…great explanation!
So, if we use your template, but switched to Bonka which are 22,000mAh instead of 10,000mAh Multistar we would need half as many pairs?
Small pack = Two 22Ah batteries
Big Pack = four 22Ah batteries.
Do you agree?
Some good information coming out here.
I would like to mention another vital component of your power system that you will be making yourself.
Wiring Harness and power distribution to all 4 ESC’s
Your going to have to buy connectors and wire to join a few batteries in series, then parallel a couple of those together, then feed all 4 ESC’s.
Your going to need thick wire (8WG at least) to handle these currents
Your also going to need connectors that are also up to task-7-8 mm bullet’s should be OK
Take a look at this video. Skip to the end to see the guys electrical mistake and what happens if your wiring harnesses aren’t up to pulling big current.
Yes but only because the Bonkas can support over 300A discharge, most other batteries can’t handle this (and personally I’m going to stay skeptical of the Bonkas until I see some more data on their reliability). I would personally keep the Small Pack at 4 batteries, just to further reduce strain on each battery while I get more comfortable with it, and I would recommend those new with LiPos do the same.
But strictly speaking based off of the datasheet the two Bonkas should be able to get the OpenPPG off the ground for a couple of minutes.
That makes perfect sense, and I think that’s a great idea. Multiple batteries work great. I use to fly 50 size electric helis. (54.75" rotor span) I was running 10S2P Thunder Power packs. I had five packs, two chargers and a deep cycle marine battery and could fly all day.
Thanks DanielArnett.
Is it your understanding that we need to build a wiring harness as Lukas suggests? It’s not listed one way or the other on the product page. Maybe if you pay the assembly fee and buy batteries through OpenPPG they assemble that, too?
They work great and they give me about 15mins with just the one set in series as you can see in the vid I shot today for you guys, because you wanted to see it in action. Some random flying from today - YouTube
All the wiring you need comes with the kits, so no need to get wiring to make your own wiring harness. I think @DanielArnett was talking about a battery wiring harness if you want to hook up you own custom battery connectors/batteries
Thanks for the video!! Super dope! So excited.
Woah, awesome. Thanks Paul!
Yeah. Great job. The final product looks very cool. I am trying to get the bonka batteries before buying the openppg. I live in the Canary Islands (Spain) and here I have more problems to bring batteries. Can you tell us where you buy them? Thanks Paul.
Is all the wiring there to hook up 8 batteries? What is the number of batteries limited to with the included wiring? If I need to purchase anything else (connectors, cables, etc.) to increase the number of batteries to the absolute max, it would be awesome if you could provide a link to exactly what to purchase. I’m not at all afraid of heaviness, and would like to test how many batteries I can get hooked up. Thank you!
Slightly noisyer than I expected but… Great!
The arming procedure and hand throttle generally looks good. Still blown away by the weight and packed size. How long does it take to open and a fix the cage? It’s all just soooo good!
(Though If my old CFI saw you without a helmet and no speedbar connected he’d fine you the price of a beer!)
I bought 4 of the Multistar 16000mah 6s 10c Lipo packs, and also 8 of the 12000mah packs. Should I be concerned that those 12000mah packs won’t put out enough amps, especially if I only use 2 for a short ride? I’m hoping to be able to mount all 8 of the 12000mah packs at the same time. Is this going to be possible using the connectors provided with the OpenPPG kit?
You need at least 4 of the 16000mAh or at least 6 of the 12000mAh.
@Pdwhite how many connectors ship with OpenPPG by default?
It ships with 4 xt150 running to the main power.
Can I pay you to add more during the kit assembly process? Or do you know of a ready-made connector which would allow me to hook 2 of those 12000mah Multistar packs in parallel to the 4 xt150 connectors that come stock on the OpenPPG (for a total of 8 battery packs)? (If not, I’m assuming there must be a tutorial somewhere which demonstrates how to create that sort of required xt150 wiring harness, a parts list, etc. I imagine that must be a fairly common situation…). If it needs to be made DIY, I’d much rather pay someone to do it.
Could we have a wiring diagram so we can see how this all fits together? It may become clearer as to what battery combos we could put together and what fittings are required.
A dedicated section/wiki on the electrics would be a huge help.
Thanks!
Hi anyone know if there is a Bonka battery dealer in the uk?..or an idea where they can be purchased online…having trouble locating said batteries
Dave
We do buy groups from Bonka every now and then, so if you want shoot me a private message with your address and how many batteries you want and I’ll see what the cost is including shipping
