How many years have their current models been in use? Just curious if anyone has any long term experience with them? Seems I have seen a few people talking about cell imbalance issues and was just curious if those were only a few random cases and/or if there are people who have had these in use for more than 2-3 years with good results?
It's hard to say on any of this stuff, this industry is changing so fast. For me flexibility is best with stuff that has a proven track record. Dan's batteries are expensive when you factor in shipping...
