  1. Miguel Garcia

    Naihatid na sa aking bahay ang baterya nang umaga dalawang araw pagkatapos ng aking order, kasama ang isang dalubhasang installer. Na-install ito sa loob lamang ng isang umaga, at sa wakas ay nalutas na ng aking pamilya ang problema sa pagkawala ng kuryente!

    PH

    Built like a tank. The construction is robust, and the specs are clearly under-promised and over-delivered.

  3. Juan Dela Cruz

    After 2 years of use, the battery still holds 20KWh like new. The 8000-cycle lifespan claim seems totally believable!
