Default Re: tech direct club Nissan leaf battery pack system is a good idea?

I have no idea about that pack but... I really do not like how they measured the capacity by draining it down to 2.5vpc... I may be wrong (and often am) but many of the people selling lithium measure them down to 3.0vpc for identifying the capacity. Your idea of two packs may be a good solution. The 'norm' seems to be 100ah or more lithium packs, so two of these should do well.

The BMS could be a problem though, max discharge of 120 amps. Your navitas 600 amp controller may pull more than that and the advert says the BMS is good for 120. Even if you connect two in parallel that's 240 amps and my Altrax 300 will draw higher than that briefly when starting from a dead stop according to my logs.

Sorry this is not much help... Hopefully someone else can provide better detail.
