You will need to purchase Leaf modules and hardware to work with this BMS kit:
- 7 G1 or G2 Nissan Leaf Modules (if G1, 4 of one type, 3 of the other)
- 6 sets of spacers(G1 only)
- 7 sets of terminal bolts
BMS Includes:
- BMS with circuit board and applicable hardware
- 4 X 12 inch threaded rods with washers and nuts
- 50A or 100A Anderson Pigtail
It is required to compress the modules for a sturdy build and proper fitment. 12 inches of threaded rod is enough to assemble the modules together and slowly tighten them in a uniform pattern for an even compression. Once you have compressed them to where the BMS kit fits, you can cut the excess threaded rod off.
The BMS app is easy to use. You can add multiple BMS's to the same app and swipe through them to view the information of each BMS. You can control the charge and discharge of each BMS individually, calibrate the voltage and current, and enable the balance function. On the main screen, you can view all the cell voltages, temperatures, and basic battery info to help you determine the condition of the pack. You can also push the button on top for a quick voltage and percent charge indication of the battery.
There are two version of the BMS, 50A and 100A. The 50A version is best suited for energy storage applications and the 100A version is better suited for mobile applications like golf carts and scooters.
The 50A BMS is rated at 50A continuous, you can get 52A for a few seconds before it auto-times out. It will allow 100A for up to one second before it times out, but we do not recommend it. The fuses are rated for 30A each, total of 120A. These are common fuses that can be replaced by soldering if you ever happen to burn them up. Using these fuses increased the efficiency of the kit and reduced the operating temperature by 30%. The Anderson wire comes with 1 foot long silicone wire.
The 100A BMS is rated for 100A continuous, you can get 150A for around 30 seconds and around 200A for about 10 seconds. These figures are on cold start, a warm or hot BMS might cut out sooner in higher temps. The one large fuse is rated for 200A. It is an easy to find fuse incase it ever burns out. Please tighten down the fuse bolts before first use, they were left snug but not tight incase you need to take it apart. The Anderson wire comes with 1 foot long silicone wire.
Golf Carts usually require large amounts of current, generally around 200A, more if it is a larger golfcart. The best way to see if this will work for you or to determine how many you will need, measure the current with a clamp on ammeter with a DC setting while applying full throttle. Divide that number by 50 or 100 and round up. That is how many of either of these we would recommend for your golf cart.
If you dont have an ammeter and can't get one, your motor controller might say how many amps it takes.
