Fast delivery, nice product,I recommend this seller, working fine yet, more reviews after few days when result comes . 5 star .
When i received this device, i was installed it, give good reviews , but after 2 days , i feel that some thing is not working properly , major fault in this device is ( not stop charging when battery is full charged) the battery boiling and smelling , when i uninstall this and review the battery manager card, there is not such system in this PCB , so buyer should be aware that when they buy this product . 1- transfer (Okey) 2- low battery cut off (okey) 3- power output when backup (same as battery power) 13.5v - 10.5v 4- battery full charge cutoff ( not working)
