As I saw many rules in Europe, US or even in Japan are tighly restricted of batteries just charge until 8.4, if goes into 8.44 would be considered overcharge then would be hardly penalized.

But i saw in somewhere of Southeast Asia still allow charge until 8.44.

Then I verified Lipo would swelling in case charge it 8.44.

Could someone tell in case the rules is allowed 8.44 would have advantage for LIHV than LIPO?

Could someone tell me LIHV could be charge with 2C?

Anyone would fully charge LIHV until 8.7 then discharge it until 8.4 before race for better perform?
