Hi everyone.
I need a little advice in regards to LiPo batteries for the EZ-B v4. I have been waiting for my dev kit, balance charger, 7.4 LiPo, and a few extras to be delivered for quite a while now, and after I sent of an email to the very helpful EZ Robot guys and gals inquiring what the delay was, it turns out that there is a shipping issue with sending loose batteries from China which has been holding up my order being sent. I have requested a refund for the LiPo and charger which has been honored, so no problems there.
So what I need the community's help with is advice on what I can safely use with the EZ-B v4. Can anyone recommend a good, reasonably priced LiPo battery pack that can hold a long charge, say about 2500 mAh or more that will work well with the v4, and a good charger to go with it? A balance or auto cut off charger would be preferred as I hear that LiPo batteries can be a bit finicky and care needs to be taken to avoid killing them.
Any advice or recommendations anyone can offer would be greatly appreciated.
Cheers,
Steve.
I have been using lipo batteries and having no problems.

Thanks for your informative response. I stand corrected about my "step backward" remark *blush* (although I did say "in some respects").
I take on everything you said about longer capacity, smaller/lighter ect, and "step backwards" was probably the wrong phrase to use. It's just taking the extra care not to let the LiPo's fully discharge and remembering to recharge them before they completely drain, even keeping them charged if you don't use them for long periods of time, and seeing £20 or £30 go up in smoke if you forget.
But as yourself, djebay, and others have said, you have used them for a long time now with no issues, so fair play to you, and I am probably over thinking things (as I sometimes do) *eyeroll*
@djebay.
Thanks for the link you supplied. Very interesting and is a good read.
Cheers,
Steve.
So now I need to order my battery and charger. While I have been looking for a battery to buy, I am seeing that there are different connection types. Which one do I need to connect to the EZ-B v4, I do I cut the connector that comes with the battery off, and attach the barrel jack that comes with the dev kit to the battery?
Steve. *confused*
to charge i pull out wires that i stuck into the deans (not micro deans) connector.

Another type of battery connector that I like to use is the Traxxas type connector. It's not as compact as the Deans type but it's easier to solder up and has a very solid connection. I usually cut off whatever the battery comes with and add these.
Traxxas connector
I cant remeber where but I saw a post where DJ Sures recomended NiHm batteries in the battery packs of the v3 for alot of the same reasons you listed as benifits of LiPo.
Maybe I misread some of the details but he definatly recommeded HiHm recargables. I remember being very happy reading it because it was the route I was going so I didn't have to keep buying batteries.
I'm not trying to confuse anybody but now I'm a bit confused on this.
@Richard. Yes it is just the EZ-B and power shell I will be using, but when I mentioned using the barrel jack, I meant the stand alone jack that comes with the dev kit. Thanks for pointing me in the right direction.
@jdebay. Thanks for the photo. That's what I had in mind, so thanks for confirming.
Steve.
@Zap Yes I am in fact talking about the AA's
I have just bought this "bad boy" which is a Venom LiPo 2S 7.4V 10,000mAh 35C. I am pretty confident that I can just connect it up to my roli and it will work fine but can anyone confirm this?
Also can anyone advise of the best setting to charge it? My lipo charger will charge up to 5 amps.
And can I also presume that the low voltage warnings on the EZB will continue to work when a higher rated battery is used?
Thanks for any advice - I would prefer to be on the right track before connecting.

Your charger should work too. However being a very large capacity battery it will take much longer to charge.... If it were me (and I am not knocking ez robot's lipo charger) I would grab a better lipo charger off of eBay...
Remember amps are "pulled" by a device not "pushed" into it by the battery... What you have effectively done is buy a bigger gas tank for Roli... Roli is still going to draw the same amount of power it did with it's original battery, however now with the larger capacity battery it will have a much longer runtime...

I would pickup the batteried from the EZ-Robot store. I don't stock them, but i do buy them from EZ-Robot.
