Woohoo! I ordered last november, #3781, got my kit today!

Well I found out today my order has been held up do to the Lipo battery, so I cancelled the battery and charger in exchange for 2 of the servo gripper hands, order was change and I now have a tracking number. I will stop whining now.

Yes, Lipo's are interesting. Many of fellow RC airplane and heli club friends have had their share of lipo mishaps. They are certainly lightweight and powerful, but if you just look at them funny, kaboom !.. massive 2000 degree fireball in less than a second. Have had friends had their car burn to a crisp after putting them on the backseat after a flight, or another friend who's house burned down after the battery was charged. I myself take great care when charging them here at home(don't want to burn down an entire condo complex, hehe).

I was told they changed the chemistry a lil so they might not pop so badly, but i dont take chances either, i charge them in a terra cotta planter pot with a lid lol. Balance chargers are the key for anything more than one cell. Has anybody checked out BatteryUniversity.com? Its everything you'd want to know about batteries and then some lol. should probably mention, i didnt order a kit, just the v4 and the camera. Might make a difference.

There are only a few containers that can contain a lipo fire. The most common are ceramic crock pots. This has to do with the very high temp they are cooked at. Some microwave ovens have a ceramic lined cooking chamber that can reduce the chance of lipo fire taking out your house. Absolute best option is to charge them outside in a portable fire pit. Some hobbiest are more paranoid than others. I have noticed over the last ten years the batteries becoming less flamable. I have destroyed cell phone batteries on purpose and the fire was an unimpressive small smoke bomb. It did get very hot but it is not the fantastic "thermite style" blaze we see in old lipo destruction videos say ten years ago.

Here in the states we pretty much ignore the lipo regulation because they allow businesses with mass shipping accounts waiver of those restrictions and then tell the individual its unsafe to return the same battery they just received from a hobby supplier. rolls eyes every cell phone shipped from my employer has a loose lipo for example and no padding at all to protect them in the event of a rough ride. Just a bubble mailer and a sticker on the outside declaring a lipo is inside.

I don't mean to derail the LiPo conversation at all, but I just wanted to say thanks to @bstaehling for the kind words, it means a lot to hear compliments like that as we are pressing pretty hard these days to get our product into your hands

I use LI-ion cell phone batteries with the installed PCBs (Power Control Boards) to build the power packs to use with the EZB(4)s. They are much better controlled for both charging and discharging than their counterpart Lipos.

Received EZ-B v4 today. Thanks EZ-Robot Team!
