Performance gaw cell quality, thermal management, BMS a kungkyang ai lam, hte hkrak ai system hpe hpawng de ai lam ni a lapran kaw nna pru wa ai-brand mying gumhkawng ai kaw na sha n rai.
Na a climate tengman ai lam kaw nna hpang u. Phoenix installation ni hta tinang hkum tinang -katsi ai hta grau nna thermal mass hte nbung n-gun ra ai.
