HELP - Specialized Vado/Como Battery motherboard replacement.


New Member
I have a low use Vado 5.0 , less than 1000 miles. Yesterday I went to charge it and a staple (the kind you use on paper) had become attached to the magnetic socket of the Rosenberger connector, and when I plugged it in there was a spark; then Battery would not take a charge. Battery turns on (3 lights of charge, 52% remaining), bike and display operate normally. Although it has low miles, it is more than 2 yrs old and 2 LBS + Spec told me replacement is the only option. (Except, get this, THERE ARE NONE IN STOCK ANYWHERE!). Charger tests normal on another bike.

So, with nothing to lose, I opened the battery case, unclipped the connectors and tested the batteries with VOM. Forunately all the cells are in perfect shape, so the BMS (Battery Management System) board did its job. Unfortunately, it sacrificed itself to protect the battery and the bike.

Now I have a $5000 bike with a dead $1000 battery and no way to repair or replace. Specialized will not sell the motherboard only, and has no idea when more batteries will be in stock.

So here's where you all come in. Someone out there has a dead battery, or a motherboard, that you can't use and I need. I'll send you $100 USD for it. Please help!

I had an issue with a controller board one time for another different application. I had another to compare it to, and found one of the diodes had failed. So being real careful, I replaced it and all was well. Something to consider if you can look for some burned connections or check diodes, etc.
