If you are using the TP batteries and balancers, then I would recommend the TP charger as well.
There is a communications cable connecting the balancer to the charger, and this system will prevent the charger from starting the charge if it is set for the wrong cell count. (Mismatch between the cell number set on the charger, and the number of cells that the balancer detects.) There will also be other safety features, such as stopping the charge if the balancer sees more than 4.24V in any of the cells. This will not work if you use a different charger.
