1. Cells are out of balance and even if you unlock it, the chip will lock it again after a few cycles.

2. 045A20 is suported only with LGC fimrware but in this battery the firmware is Sanyo which is not supported.

@torture thx brother...

ask,Why are there so many batteries that are not supported, even though these are old batteries?

Do you know a software that supports all of the chips on the market?

Please let us know.

@torture i just want to know,its because programmer device or something?

 It is because your license limitations. 

 Please check the supported chip list you paid for.

There is no Renesas 045A20 chips there at all. 

@djibattworkshop BTW, if so, are these licenses for sale?

 We not sale Renesas license. But you could ask another companies. Keep in mind they are very expensive. 

@djibattworkshop 

045A20 with LGC is present in the support list.

@sajantherev

For the moment 045A20 with Sanyo is not supported, even remotely. We work to add more and more chips, once we have the solution you will see it.
