E te maua se toe totogiina atoa poʻo le 100% aitalafu faleoloa pe a uma ona matou mauaina le afifi toe faafoi ma siaki. O le toe totogiina o le a faʻatautaia ma tuʻuina atu otometi i lau auala muamua o le totogiina.Faamolemole ia matau o tau o uta ma soʻo se tiute poʻo pili e le mafai ona toe totogi. O tau faaopoopo o uta e le mafai ona toe totogi pe a uma ona lafo le afifi. O oe e nafa ma le totogiina o nei pili ma matou te le mafaia ona faʻamagalo pe toe totogi, tusa lava pe toe faafoi le oka ia i matou.Pe a matou mauaina ma faʻamaonia lau mea toe faafoi, o le a matou lafo atu ia te oe se imeli e taʻu atu ai ua matou mauaina lau mea toe faafoi. O le a matou faʻailoa atu foi ia te oe le faʻamaoniga poʻo le teena o lau toe totogi.Afai ei ai ni faʻafitauli e uiga i le faagasologa o le toe totogiina, faʻamolemole faʻafesoʻotaʻi matou. service@roymall.com poʻo Whatsapp: +8619359849471

Troubleshooting:
Fault phenomenon	Fault check and cause	The solution
Unable to charge	Measuring the voltage of 4 groups of batteries. when one of the battery voltages exceeds 4.25V, the protection board will activate overcharge protection.	Pair the battery pack well, do not mix the good battery and the bad battery.
Unable to discharge	Measuring the voltage of 4 groups of batteries. when one of the battery voltages is lower than 2.7V, the protection board will activate the over-discharge protection.	Pair the battery pack well, do not mix the good battery and the bad battery.
Charging/discharging failure	0V, 4.2V, 8.4V, 12.6V, 16.8V miswired	Rewire or replace the new board (human failure, no warranty)
Overcharge/over-discharge failure	0V, 4.2V, 8.4V, 12.6V, 16.8V miswired	Rewire or replace the new board (human failure, no warranty)
Discharge protection	Check that the battery pack has sufficient discharge capability and check that the load"s starting current exceeds the over-current protection current of the protection board.	Replace the battery pack with a higher discharge capacity, or a protective plate with a larger current (super working range)
Component soldering	There is no connection between one of the components and the PCB pad.	Repair welding
Component welding	There is a short circuit between two or more pins of the component.	Remove the component and re-weld
Electrostatic breakdown A	In the unpowered state, measure the G, D, and S poles of the MOSFET. If the forward and reverse resistances of any two pins are 0u03a9, it indicates that it has broken down.	Remove the replacement MOS tube
Electrostatic breakdown B	Remove the MOS tube and measure the resistance of the G and D, G and S poles of the MOS tube. If there is a resistance indicating that it has broken down, the resistance should be infinite.	Remove the replacement MOS tube
