Was very excited to receive 2 of the advertised 24V plug and play A123 battery boxes from bigbattery. That excitement faded fast during the first charge. I am replacing a 48 V leadacid system and set the new batteries in series settind the fm80 well within the published battery specs. Nearing absorb voltage the battery voltages started to diverge drastically by about 0.7V so I stopped the charge test while on batt was still well below absorb. I have since done a discharge test and it looks worse than anything else I have heard thus far. On cell is waaayyyyy low on charge and discharge and several others are alightly out of balance.
Then did some forum searching and found other instances of mis balanced and possible bad cells. Definitely wish i would have read those before ordering. Now it looks like I'm stuck with a bad battery.
I will follow up with the test results later. I jist wanted to get word out that these batteries are fairly cheap for a reason. All made the more complicated by the $275 freight to Hawaii. Feeling pretty screwed...
