Needs BMS - Tracker Lithium WRM60 Lifepo4 12.8v 60ah

These batteries in particular need a BMS. We have 30a and 100a BMS units in our accessories sections that are 4s lifepo4 units that will work. We already used a dremel to open the lid and the balance leads and main wires are easily accessible. Should only take a few minutes to swap the BMS. The cells will test like new and they are all balanced. The lid we used duct tape around it and it holds perfect.

If you are sizing for your boat this would be a group 24 size equivalent battery. At this price you can save money on your solar storage and really save money if you are looking for a battery for your boat.

These batteries can be mounted any direction, even upside down. Doesn't matter because they are cylindrical lifepo4 cells inside that don't need compression.
