Very happy with your 24V power supply and the Hyperion charger....have cycled the pair of 4s Lipos you sent.
Pleased overall with your product (first-time customer)!!

Versatility at its best!

This charger is among the most versatile chargers on the market. The manual leaves a little to be desired, but the YouTube videos uploaded by the MaxAmps team are a huge help!
