300a BMS Tracker Lithium WRM100-HP Lifepo4 12.8v 100ah - Tested

This battery in particular had a faulty BMS. We added a 300a 4s BMS so now the BMS is super sized. We ran a complete test and the battery tested over 100ah. So this one has never been cycled until we tested it and the cells are all new. We had to cut open the lid to swap the BMS but we taped it back together and now it functions like a brand new battery. Please limit the charge to 50a continuous and discharge to 100a continuous. The BMS can handle more but the busbars are only sized for 100a continuous.

These batteries come fully tested and include the printout of the test report showing capacity and graph.

All of these batteries have tested near or above new capacity.

This battery can be used as a starting battery since it can push 600a for 2 seconds. You can charge up to 50a continuous and discharge up to 100a continuous. Fully charged voltage is 14.6v and fully discharged is 10v. You can parallel up to 12 of these together. This model in particular should only be used in 12v applications. You should not series these into 24, 36, or 48v. The TLi models can be used in series because they have a different BMS. This is a great all around battery for any 12v application and works great for starting power.

Notice the photo, the threaded part of the post is broken but you can still use the clamp style connector and you can even tap and dye a thread into that if you want to make your connection with a bolt and ring terminal. We discounted these with the broken threaded post. Otherwise the battery is in perfect working condition.
