Nice product, easy to bind with JK BMS (invertor model) Review by Sparky

Rating

Easy to connect with JK BMS 300mm long board (comes with communication board, aka. invertor bms). Just detached one by one all balance pins (used tweezers, but be careful not short the pins, because it'll cause permanent damage of certain balance leads line) from existing connectors and repacked existing bms's connectors with their. Also, took fourth of eight temp sensor's connections and do the same stuff. Pretty easy 30min job to rewire whole battery, as a bonus no need to use provided pcb and have a mess with a lot of wires.
There is enough space (on front side, where is a rectangular hole) to put the pair of 200A connectors, MCB, MegaFuse Holder, BMS and communication board. BMS board better to attach to battery (I used four longer M4 bolts and two 3d printed brackets, used to hold the lifting plate on the outer side (4 others left as is). Others components were attached to acrylic, 3d printed, metal, or other material plates. Best direction to assemble: 1)Lift a battery module; 2)detach built in parts (solar connectors wire lum, CAN communication board and cables, heating pads); 3)attach the plate with mounted connectors, mcb, fuse and bms communication board to the casing;4)attach bms to battery module;5)wire bms and battery terminals together;6)place battery module back to the case.
Hope I'll help someone.
P.S. you can also put some sort of relay on the back side to control the high voltage heating pads if you needed, but I suppose to buy low voltage pads insead (Posted on 17-12-24)

Excellent battery Review by Олександр

For installation, I used the JK BMS B1A20S15 board.
I cut off the standard connector of the battery balancing wires and soldered the balancing wires from the JK BMS.
I cut out the front panel from textolite and mounted the terminals for connection there and brought out the power button.
All the cells were well balanced, had a voltage of 3.28 volts and had the same resistance.
The battery started up successfully and is ready to work. (Posted on 28-11-24)

Easily connected to JK BMS using the PCB. The battery came almost perfectly balanced, internal resistance is 5.45 mOhm. Perfect price/value ratio (Posted on 25-11-24)

Good product and best seller Review by Taras Chaykivskyy

I bought this battery at the end of October 2024, it arrived late due to a car breakdown, but it was delivered intact. The case does not have a single hole for connecting cables, so I had to redo it: dismantle the radiator, install a plexiglass window instead of the radiator, install the BMS. As it turned out, the BMS mounting board appeared in mid-November, but I wrote a letter and they sent it to me for free. For which I sincerely thank you. The battery is already installed and working.

Burning the cable inside Review by Andrii

Rating

The package has arrived. When the package is opened, the smell of burnt plates is very strong. When I removed the metal cover, I saw traces of burning BMS wires. They allegedly touched the metal body. I don't know what to do now. (Posted on 23-11-24)

like it Review by Serhii

I have already bought several units of this battery. To be honest, I didn’t expect to get such a good quality battery for such a low price! Upon disassembly, I found that the battery is well-manufactured and made of high-quality materials. I only added a BMS, and that’s it. Very good quality for this price. (Posted on 21-11-24)
