Has anyone ever built a 69er ebike before ? 29 inch wheel in front and a 26inch wheel kit in the rear? I was wondering how that would ride say above 30MPH. Just wondering.

Very motivating, guys. Thanks to all.

i've just realized it's not possible.

I'Ve just realized that it's not possible.The black wire is common ground for all yellow ones.

Is it possible to connect the 12v output in series to charge a 48v pack with just one single ps? this is to be used on the road.

I have letz say 14ah of 48v sla, and I want to use one single small form factor PC power supply to charge. How do I go about doing this? First I would have to connect the green wire and the black wire together. Then branch the 12v rail to 4 plugs and connect them in series, then add the 5V rail...

It does look like LIFEPO4 might be better deal overall, safe + longevity.. Maybe I should cut corners and save up money for a few months to cough up about $600.

It looks like laptop batteries are better in a sense that they have already BMS built-in and proven to last a few years.

Does each hard case pack has built in BMS to prevent overcharging about 4.1V and over discharging to below 3.5V?

My friend said he knew where to get them. Not sure where. He said something like 12.99 per pack.

How many AH is on that pack you built that gets you about 11 miles??

I read that these Turnigy Lipo will last about 100 cycles. Is that true?

How could you tell if there is a dude cell?

This price seems pretty reasonable. I wonder why. It seems to be cheaper than other Lipo packs.

These are HP OEM original battery, haven't been used, but probably very old stock.
