makikita mo sa serial kung anong klase 18605 from 2000mah to 5000mah depende sa klase

kung 4*2500 = 10000nah
pag 4*5000 = 20kmah

yung 15kmah ko na na charge sa 8hrs ang battey voltage across sa terminal is 4.1v ng naging blue yung red charging light so it will be mga +-95% sa full charge. itong 15kmah power bank nasa 3rd week ko na ginagamit so far walang aberya


yung 30kmah battery bank naka initialcharge na ng 13hrs+ it is still 3.8v at di pa nag change yung charging lights. ill post later kung ilan ang oras at anong voltage pag nag palit ng kulay ang charging light.

 

[runaldo]

ayon sakto meron ako dito 6 pcs laptop battery hhaha.. lagay ko kaya lahat ilang mah kaya

 

[rscc202]

Update

30kmah full charge pagkagising ko. 4.08V sa digital volt meter ko. mga +-95% ng battery capacity. dependent ang volt cutoff sa nabili na powerbank galing cdrking

ayon sakto meron ako dito 6 pcs laptop battery hhaha.. lagay ko kaya lahat ilang mah kaya

paano i charge mo battery hangang 3.7V tapos i rest mo sya ng 8 hrs. pag bumagsak ng 3.3v below sira na battery mo. pag sa mah i search mo sa net serial para makita mo specs
