4pin 5pin Hailong Polly Ebike Battery Bottom Base G56 G70 DP-5 5C 6 6C 9 9C Mounting Plate Bracket Holder Fixing Electric Bicycle Battery

This product was just what I needed to use an expensive battery on two different e-bike builds, a longjohn cargo bike and an upright bike with a Paul Flatbed basket. The fit, quality and included fasteners and connectors exceeded my expectations.

It came from China very quickly. Packaging is very thorough and protective. I have a Joyisi 36V Li-Ion battery with a 5 pin connector & it fits on this battery base perfectly. This comes with 2 black & 2 red power pole connectors, a set of XT60 connectors, 3x M5 screws & 2 rubber pads. The base has red & black wires on which I crimped the power pole contacts. I have my original base on my bike & I will use this base in my home to check battery voltage & make sure my wattmeter is working. I charge only through the XLR connector on the battery. I would not charge through the output wires because with Li-Ion I want to be very careful.

I used it for my battery to mount to on my e-bike. My battery melted where it connected to white. Not sure what caused it but it’s made better than the one that came with battery originally. My thoughts are this name brand is better then the other brands.I bought the newer version battery again.

I bought this extra base (Hailong 2) to mount on a second bike in order to use a battery I already had. It works fine after resolving 2 issues. The first was easy: Initially the battery would not slide into the base to mesh the connectors. This was solved by slightly bending the pins to align with the battery. The second was a bit tougher: The wires from the base must be 8 awg, pretty darn thick. Although they provided different connectors to match my wiring, the thickness of the wire made it impossible to use the Anderson connectors. I ended up switching my wiring to use XT60 connectors, which have to be soldered on. Thick wire can carry a lot of current, but I wish they used a bit thinner. All in all, though, a good item.

I got the 5 pin Hailong type which was identical to the one that came with my Unit Pack Power 52v 19ah electric bike battery. It comes with about 8 inches if cable attached, and comes with both a set of Anderson and Yellow XT-60 connectors but be aware you have to solder them to the cable yourself. This base works great if you want to switch your 500 dollar battery between two ebikes or in my case I hooked the battery up to a DC-DC power converter to output 12 volts when I need it.

Great thanks

Used it to attach my existing e-bike battery to a kayak trolling motor (other parts were involved) and it does as it's supposed to.

The more ebikes you have the more battery mounting bases you need. Just swap one battery for multiple bikes. This is number 2 for me. It comes with the hardware to mount it as well. Just match the look of your base to the picture and order. You get the right one.
