ZIPPY 5Ah 6S 15C batteries

[LegendLength]

Would these batteries be acceptable for use with a BMC v3 motor: ZIPPY 5Ah 6S 15C batteries ?

I only want to run the motor at 36 or 48 volts at the moment as this is my first build. I don't have any experience with lipo batteries and I would like the batteries to be as plug-and-play as possible. I know the ping life batteries are better in that respect, but I wonder if it's even possible to hook up lipos without any soldering.

Is it possible to pay for a custom wiring set fairly cheaply? Would that make it plug and play on my end? What about the BMS is that an extra module I need to choose, or is the wiring the BMS itself?

Sure, it would be fairly simple to soldier up some leads, however, for someone to do it for you might be a little tricky, best to have someone local that can see your set-up to get the lengths of wire just right, and the shorter the leads from battery to motor the better.

Where are you located? Maybe a member here lives close enough to you?

I've purchased several sets of those exact packs and use them 12S with 35A controller. I always figured 15C should be good for 75A. Interesting thing is they stay in balance better than any of my 20, 25C packs.

With Lipo - you gotta be ultra careful to avoid low voltage discharge and there's really no plug & play solution to these rascals. But, 12S isn't too complicated to charge with a decent RC charger and eventually work up to a Meanwell. The RC charger will still come in handy for occasional balancing, troubleshooting and maintenance. 12S should never drop below 39V and it operates mostly around 44-46V for much of the discharge curve. It's a good way to go for 36-48V nominal systems...

4 of those zippy's will make a nice 10 ah 12s pack. So that's 12 cells in series made by pairing two packs with paralell connections, then series connection the two pairs to make a 12s pack. It would be niether 36v or 48v, but halfway between the two. Charging would be fairly simple with a pair of RC chargers. Unplug the series connection, and charge as two 6s packs.

Various methods could be used to connect em, or make a connecting harness without soldering. I like to crimp andersons, so I did mine by replacing the connectors with andersons. You can see how I did it in the lipo noob thread links. It's a sticky thread above. Since I keep re- arranging my batteries constantly, I do not paralell the balance leads. So occasionally I still have to balance my packs by charging them one by one. If you only have one bike, then paralell the balance leads too.

For the bms, you have the charging side of your bms built into the RC chargers. Then for discharging you want one or another type of low voltage warning devices. One for each paralleled set of 6s batteries.

I have 2 of them in 12s lipo battery and at 44.4v it goes 28 mph on my new BMC. My 36v ping works great on it too.

I smell a business opportunity here. What would it take to make 36v10AHr and 36v5AHr packs out of Zippy or Turnigy packs that was as plug and play as the typical Ping E-Bike battery?

There are millions of E-Bike batteries out there (in SE Asia!) and they're almost all 10S Lipo or 12S LiFePo (I think) with a built in BMS. So this feels like a simple case of sourcing the BMS and making up connectors. Can Ping supply the BMS on it's own?

Maybe Ping needs to be persuaded/encouraged to make up packs that use the same cells as Turnigy with their high C rating as an alternative to his prismatic cell based batteries.

In regards to the leads and connections, you don't have to solder, you can use crimping with (for example) Anderson Power poles.

You can get ready made wiring - there is ready made parrallel power leads and parralelled balance wires on this page

Just make up your mind before you start as to what type of connectors you want to use (eg Bullets or Andersons etc..). Andersons have the advantage of not needing solder (you can crimp them), but they are a hassle without the crimping tool in my opinion, which is $40 odd dollars.

Lipo does require much more work, caution and attention than a Ping.

I run a BMC V3 on 48V lipo, and I run the controller at 40amps. I think you are wise to limit yourself to 48V max on the BMC V3, they are notoriously unreliable on any higher voltage/amps (phase wires melting and gears getting chewed). But if you are staying at 36V then in my opinion you definately want to go with 40amps on your controller (and in my opinion 48V needs 40amps as well, but I have seen some argue that the amps should be lower at 48V). But my BMC V3 has run fine on 48V @ 40amps.

I would have thought a 10ah or 12ah Ping battery would struggle with 40amps? But I might be wrong, I thought they were 3C, in which case 40amps on your controller would be a bit much for it if I am right on the C rating (I may be completely wrong on that C rating, I thought I read that somewhere). I moved from LifePo4 to Lipo and never looked back, but you do have to be prepared for the extra effort, and that it is definately not "plug and play" (not only in setup terms, but in care, maintenance and charging compared to Lifepo4).

Cheers, Phil.

I'm still a bit confused because this zippy 6s seems to have neither bullets or andersons, but instead has dean's connectors. Or are bullets the same as deans?

If I decided to use andersons wouldn't I need to replace the existing connectors via soldering?

 

[dogman dan]

Hmm, interesting. The pic shows bullets, but the spec says deans.

I just crimp all my andersons. And put andesons on all my stuff nowdays.

New link on how to crimp in lipo noob thread links. A great vid on connectors from Ypedal.

Hi Dogman,
Your links on this thread are missing (at least on my browser). Did you type these in too late at night?

Charging would be even easier with this single rc charger, one charger instead of two and no need to unplug and charge as two packs:

[dogman dan]

No, I just wanted to make you work. go to battery section, and see the sticky thread where I put all the links. Lipo noob thread links is the title.

Here is a 7.5" x 4.5" x 4.5" 10AH 44.4V Turnigy pack I built up with deans connections.

4 x 5000Mah 22.2v 6S1P 25C packs (they peak at 25.2volts off the charger). split into 2 in parallel packs and then seriesed those for 44.4v nominal (51V peak).
