No, you have to buy the charger separately.

Yes, you can connect up to 4x 12V liFePO4 batteries, or 2x 24v in series to make a 48v battery pack. Note: 12v 50ah batteries can only be wired in parallel and cannot be connected in series.

We gladly accept returns within 30 days of receipt for most items in new condition. If an item is new, unused, and in the original packaging, we are happy to accept a return up to 30 days from the original invoice date with no restocking fee

LiFePO4 batteries have a much higher cycle life of 3000+ cycles compared to 600 cycles to other li-ion batteries. Another big advantage is safety as there is no risk of explosion or fire.

Yes, the BMS does have a balancing function and it will keep the cells balanced.

13.6v is the resting voltage of Lithium cells. The battery at 13.6v is still 100% charged. It is totally normal.

We also sell batteries with Bluetooth connectivity. Please check our products.

Yes, it does handle high current for 3s. Please check the specifications for each battery to check the high in-rush current supported.

Our batteries are built with Grade A prismatic cells. That makes the failure rate much lower than the batteries built with cylindrical cells, because we use fewer, but larger cells.

Yes, it can be used for powering trolling motors. Check the specifications of our battery and the power output of your trolling motor.

No, our batteries are not meant to start up the vehicle. The current is too high so the BMS will cut it off to protect the battery.
