Showing my e-bike ignorance here, but does the rest of the bike's electrical system need this exact PCB in order to function? If so, I guess my only real option would be to attempt to charge these pouches or connect new pouches to the existing board. If not, I think I'd rather swap the whole...

I guess my main question at this point is whether something else (like a Ping LiFePO4 pack with integral BMS) could just drop in and replace everything seen here. Their 24V 10AH is relatively inexpensive and seems close to the original specs. Should I be able to just wire it up to the factory...

Two sets of 7. Measuring the voltage on the sense wires when plugged into the charger, I get: 1. .422 2. .409 3. .253 4. .497 5. .500 6. .497 7. .494 ... if I'm doing this correctly (probes side by side, moving down the row). I get about 3V on the combined wires, slowly increasing. That's...

After looking at this circuit board, I was surprised at its complexity. Could battery management and the "brain" of the bike (speed governor, motor control, etc.) all be contained inside the battery pack? If so, I wonder whether it would ever accept anything other than this exact arrangement of...

Thanks, Doc. I opened it up this afternoon. Here are pictures of the connector, the board, and the cells. Sorry about the sasquatch leg in the background. While we're at it, could you explain the function of T/S/C/-/+ in a battery setup like this? I presume there's a pair inbound from the...

Thanks. I spoke with Electric Vehicles NW and they confirmed Giant no longer offers batteries (or any parts) for this model. After a night of research, that seemingly leaves me with three options: 1. Rebuild the original battery pack with newer Li-ion cells. 2. Find someone who knows about...

Hello everyone, first post. I recently got a fantastic deal on a never-used Giant Revive factory EB (AKA Spirit) gathering dust in a dealer showroom. The only problem is a completely dead original Li-Ion Mn battery pack. It probably hasn't had a charge in several years. Assuming that Giant no...
