Ace Tattu 650mAh 75C 4C 14.8V (XT-30)

The Ace Tattu 650mAh 75C 4C 14.8V pack is a 4-cell LiPo rated at a high 75C discharge, giving it enough punch for blasters that need stronger, more consistent power delivery than a standard 2S or 3S pack provides. It terminates in an XT-30 connector, so check that your blaster's wiring or ESC/MOSFET setup uses, or can be adapted to, XT-30 before ordering.

This particular pack is confirmed to fit and perform well in the HC Diana blaster, so if that's what you're running, this is a straightforward drop-in battery rather than something you need to test-fit first. At 650mAh it's a compact capacity built around punchy 4C-class output rather than long runtime, so it suits shorter, higher-intensity sessions over all-day marathon use.
