Hello again folks,

The topic of my question this time is batteries. I bought the LRP Flow X TC ESC for my Xray T4 and it has an input of 7.4V. I was searching a lot for good 7.4V batteries on the market but most of them were either discontinued or sold out. I find all the time awesome 7.6V batteries and few 7.4V batteries that I don't really like. Will those 7.6V batteries fry my ESC or reduce its lifespan? Is that 0.2V a really big difference?

Also I would like to know if EFRA allows batteries to be charged above 8V. Some people tell me this is forbidden but I found some pdfs on the site of EFRA that say batteries can be charged up to 8.4V so what's up with that?

Kind regards,

Boris

The charging voltage limit is 8.4V
So you can buy the higher voltage (8.6V) lipo batteries, but you can still only charge them to 8.4V and when you do that they don't perform as well.
