There have been many posts about this. In general, it’s not that good. If you want many mAh, yes, but the C rating is false - it’s more like 2-3c (lots of voltage sag).
This one is much better. I switched from 25c to 45c.
The 45c battery has far less voltage sag and way more punch to it. It also gave me more range.
I’ve got no regrets.
I got the 2x 5200mah 6s versions of those and ran them in parallel. I can definitely confirm after 3.8v theres a lot of voltage sag. but from 4.2v-3.8v its not that noticeable. and i got some pretty steep hills where I live and I can go up most of them. but if im going full speed then want to go up a steep hill it would’nt preform very well.
On a mtb you definitely need a much higher discharge rate. HK lipos C ratings are exagerated, a 60C might only deliver 18-20C so you definitely need more packs. @Namasaki has a very good lipo setup so you just take a look at his build
i just bought those multistar ones but in a 10ah version. haven’t had a chance to test em yet but even if they suck, they were ment to be backups anyway
I was using Multistar 4s 10000mAh to get 12s (3x4s) and I HIGHLY NOT recommend those batteries. That “10C” is far away from reality.
I used them under 50A load only and they puffed already. So…no, they are not good
