Thank you very much for Your reply. Especially thanks for documents about A123 batteries. It is very interesting, that such a small difference in dimensions can affect the performance of batteries. That a pity, that I did not have this document earlier, because I didnt know that pressuring of...

Thank you very much for your reply. This is interesting idea, but. As you can see from pictures, all 16 cells are together, so last one and first one cell from first and second pack is in the middle of whole pack. If you know what I mean. More over, whole pack is really tight inserted in kevlar...

Hi, I would like to ask you. I have A123 LiFePO4 pouch cells 20Ah on my ebike. I bought them from Cina, from Lithium Batteries,Motorcycle Batteries,Solar Batteries,KOK Power Limited. They got me very good price, two years before. When I got them, I was amazed. All of them had exactly 3,300 V. I...

It looks, that the temperature doesn't affect it. Because I had same problem, if there was 10 or 30 degrees outside. The motor was never hot or warm. Just I noticed, that controller short time after switch on is warm, may be 40 degrees but without load. I dont know if it is normal or not. But...

Thank you for your reply. I read all possible treads, which I found already. But, when I have connected Hall sensors, there is no beeps from buzzer after switch on. Only, when I physically disconnect hall sensors, from controller, there are 2 beeps. So, it looks like, that controller, doesn't...

Hi, I have installed on my bike Magic Pie 3 motor with Magic Controller V2. After around 5000 km I have problem with throttle, or better says it works only without connected Hall sensors. So I tried all possible checks. Hall sensors they seems to be ok. Why? I disassembled motor and check...

Hello guys, I need some quick help from you. I build up battery for my ebike from lifepo4 A123 pouch cells. At final stage, when I wanted to put whole battery in pack, I noticed some smole defect. It looks like, that, there was no impact from outside, but there is probably some defect in inner...

Hallo, I would like to ask you. Are you satisfied? I am very interested about these batteries, but I'm a little afraid of the quality. Because the price is unmatched. Thanks

Unfortunately, Slovakia is not in the list of countries with free shipping. So, I do not have other possibility as wait, if something will be changed and Hobbyking add some batteries also for EU market with some good prices.

Hm, I did not find any sale of Multistar batteries. The problem of International shipping is very high cost, when I am from Slovakia in Europe, shipping from worldwide store is around 80 USD.

Hi everyone. I am new here, but I read a lot of topics here before. I have DIY e bike. I have been used Turnigy Li-po batteries, but they start to be weak. I am thinking about change. I would like to use 26650 5000 mAh instead Li-po. But, no Li-ion is so hard as lipo, as we know, and cut off...
