Hailong G56 Case / BMS fittment

Post by Magsy » Jul 14 2020 10:24am

Picked up a couple of the Hailong cases 'G56'.

56 cells with holder and a 52v battery indicator Here

I was excited to build in this case because it looks like they had fixed most of the quirks and I thought it would be fast and easy. It has a better mounting plate and the holder allows you to make a nice 14s4p pack.

However, there is no space for a BMS. I assumed it went at the top and the slight bulge in the back of the case allowed for a thin one.....but no.

I can't seem to find any pictures of one open with a BMS installed.

I did actually glue all the cells and by gaining a few mm over the holder, it is kinda possible to put it on top but it is so tight it feels like an accident waiting to happen.

I have very reasonable size BMS, either JBD/LTT one which is about 100mm x 60mm x 10m or a Neptune 15 which is even smaller.

There is perhaps a sliver of room at the side of the battery for something about 50mm x 50mm x 8mm but I struggle to find a BMS to fit in there.

Anybody have experience to share? Thanks

I did but m sadly had to swap to a cheaper less functional BMS that was smaller :(

I actually bought three until I got one in there!

In the end, devoid of any useful information from the seller/internet on this case, I decided that they must have intended for the BMS to be on the side.

It’s still a BMS with balance and ovp/ocp/lvp etc but I lost Bluetooth. Fit is tight but ok.
