Crytalyte 5304 with a Lyen Edition controller, 72v @ 65Amps and 20Ah of A123 will climb just about anything.;)

The Chinese Duct-Tape people have come on in leaps and bounds over the last few years, it has to be said, and their communications have improved no end. I bought two of their batteries- heavy blighters, but they both worked and both provided a lot of power.

The real test is going to be how many cycles you knock out of it, unfortunately it is impossible, obviously, to determine that so early on. LiPo is more powerful than LiFePo4 in terms of power-weight, but A123 when paralleled in large enough groups is seriously powerful. 20Ah of 1C cheap...

That is true.....Pings batteries are expensive. In fact, relatively speaking, they are sufficiently pricey to mean that if you have any money at all to spend you are as well off going beyond Ping LiFePo4 and into the realm of A123. In for a penny, in for a pound. I can build you a battery if...

It's hit and miss. HM Customs simply do not employ enough people to do every package. Think of the sheer volume of stuff entering the UK from all over the non EU world. India, China, Singapore, Thailand, HK etc. There are some hints: if your delivery is sent in by UPS, DHL, etc..then it...

Pings battery will be lighter, as it is made from pouch cells. Pings build quality is also better.

The smart thing to do is get a supply of the cells and weld them into a battery of your own. I have a tab welder. I made two batteries, one is a 24v 9Ah rated, the other is 24v 11Ah rated. You can get the batteries in small quantities to avoid the customs, and build up your supply over...

The law is an ASS. The top speed for cars is anywhere from 5mph to 80mph. But the cars all have a top speed of OVER 100MPH!!!!!!!! The test should not be what our bikes are CAPABLE OF. The test should be what our bikes do at a certain time, at a certain place, and under certain...

BMS would be included, heavy gauge wiring would be used to just make life easier all around, and not that hard, stiff junk either. The cheaper packs, you can pull 20Amps out of them. There is a more expensive variant planned, which is built out of cells with a 15C peak discharge. Obviously far...

Please excuse my intrusion, but I am going into the manufacture of LiFePo4 units with a view to supplying the British Isles. I can sell them for £225 Stg with £40 delivery in 3 days by courier. Is this an acceptable price, or would I be wasting my time? Thanks.

The tabs are quite cheap, and shipping is probably very low.....most sellers send stuff by USPS Priority Air Mail and that takes around 2 weeks or 12 days. I will order bulk and then come back and see if anyone here is still interested....:cool:

Yes, I heard about these welders, and I am making inquiries about them. Here is a link for some nickel tabs......eBay.ie: 50 Solder Tabs. Build your own battery packs. (item 350316912267 end time 16-Mar-10 00:28:44 GMT)

Hi there, could you please post a basic schematic of how to connect these Turnigy packs in series and then in parallel......I also like your set up, it's very tight, all round. Well done.
