shadowjk, this was about BSI aiui. Depending on algo used in BME the parallel Rs of 2 pcs BL-5J might actually result in a better BSI reading and more correct capacity-designed value reported. For sure it won't hurt or break anyhing. Paralleling 2 LiIon is yet to evaluate. Not sure if it's ok, for NiMH e.g. it's absolutely forbidden. For LiIon my educated guess would be it should work.

[edit]
oops, of course the charge termination current threshold SHOULD be adjusted to be (twice as high - "nominal system load"), otherwise bq24150 might never detect charge end condition
