Ndai hkrat sum ai ladat gaw, hpa majaw ahkyak ai jai lang ai lam ni hta, lahkawng ngu na makawp maga ai layer ni nga ai hpe sang lang dan ai.

Madung hte lahta tsang makawp maga lam gaw hpa shai ai kun?

Primary makawp maga ai lam gaw, shinggyim masha ni a n kaja ai masa ni hpe bai htang nna, shi hkum shi bai hkam kaja wa ai. Lahkawng ngu na makawp maga ai lam gaw, shawng nnan na makawp maga lam n lu galaw ai shaloi, shamu shamawt wa ai, circuit hpe fuse (sh) non{1}} hpe bai gram lajang mai ai thermal switch hku nna prat tup n-gun n jaw ai. Ndai layered ladat gaw, daw ni hkrat sum ai lam ni hte pyi, shim lum lam hpe madi shadaw ya ai.

Lithium-ion battery yawng hpe makawp maga ai lam ra ai kun?

tara shang lithium-ion battery ni hpe dut shabra ai hku nna makawp maga ai lam ni lawm ra ai. "Raw" cell ni gaw makawp maga lam n nga ai raitim shinggan makawp maga ai circuit ni gaw shim lum lam jaw ai system ni hta sha lang ra ai. Battery hpe atsawm n hkang ai sha, n makawp maga ai cell ni hpe jai lang ai gaw, wan hkru ai lam hte bawm kapaw chye ai lam ni hpe shabyin ya ai.
