Default Batteries.

Hello. You have problably experience with all these chinese batteries. I have free space about 124mm(length) and diameter 12mm. I also need about 10 volts. So what would you suggest me? I thought to put 3.7v two batteries in series and then add maybe one 1.5 volt battery in series. Is this ok if i put two li-ion batteries and 1 usual recharable aaa in series
I thought about two 10440 batteries in series but i cant find any reliable company, all chinese. What do you think about trustfire,soshine? Thats all i can find from ebay. I would prefer something german made, but cant find any... Please share your experience with me. Thanks.

We can help you a lot better if you actually tell us what your device is. How have you determined that only 10V will work? What is the tolerance?

DO NOT put two Li-ions and a rechargeable AAA in series. That would be a good way to set your house on fire or blow something up.
