Li-ion/Lifepo4 3s-21s 100a BMS W/ LOW TEMP CUTOFF

-------------------- Here are 100a BMS units. We carry 3s-21s and both Lithium Ion (Li-Ion) and Lithium Iron Phosphate (Lifepo4). The lithium ion version also works with Lithium Polymer (Li-Po) since they both have the same parameters. (WIRING DIAGRAM BELOW!) Some of the BMSs arrived without the main leads soldered on but will include the balance leads!  A lot of our customers would prefer that as it allows them to solder their own wires on. Note: We have a BMS that works for 7-17s Lifepo4 batteries. Wiring diagram shown in the 4th to last photo. We also have a BMS that works for 6-21s lithium ion and the wiring diagrams are shown in the last 3 photos. When you see short that means all the "short" labeled balance wires get connected to the same battery positive like the 7s wiring example in the last image. --------------------- Protect your battery investment with this reliable BMS that will disengage charging your batteries in freezing weather and avoid damage to your batteries. It is very important for batteries to have a low temp cutoff because you can destroy your batteries by charging them in freezing temperatures. It was hard for us to find a BMS with all the features people want so we had to get one modified. This is actually a medical grade BMS trusted by manufacturers that make batteries intended for medical and military applications. This BMS is built solid and comes with 2 10 gauge positive and 2 10 gauge negative silicone wires. The overall construction is built to last. Bluetooth is optional. You can purchase the bluetooth attachment HERE -------------------- The bluetooth apps can be downloaded from the Google Play Store for android or in the Apple store. There are a few options there but most of our customers use the app with the little elephant logo on it. -------------------- We ship every day from our family owned and operated warehouse in Pennsylvania. No more waiting months for shipments overseas. -------------------- We do not offer technical support for the BMS -------------------- *DIMENSIONS - (3S-16S) - 5.5" X 4" X 5/8" *DIMENSIONS OF 20S ONLY - 7.5" X 4" X 5/8" Lithium ion and polymer settings Overcharge voltage per cell: 4.2 Overdischarge voltage per cell: 2.8 Discharge Continuous Amps: 100 10 second Discharge Burst: 200a Charge Continuous Amps: 60a Balancing Current: 60mA Low temp cutoff: 32° F (0° C) High temp cutoff: 167° F (75° C) -------------------- Lithium Iron Phosphate (Lifepo4) settings Overcharge voltage per cell: 3.65 Overdischarge voltage per cell: 2.5 Discharge Continuous Amps: 100 10 second Discharge Burst: 200a Charge Continuous Amps: 60a Balancing Current: 60mA Low temp cutoff: 32° F (0° C) High temp cutoff: 167° F (75° C) ----------------------
