First off, I would like to test it to see just how much capacity it has. At work, we have what is called an "Alphabat" made by Emrol. It's a load tester for deep cycle batteries. Basicly, you input the rated AH, and the machine puts a constant load on it until the battery is dead, then it gives the battery a percentile grade based off of the rated AH. Problem is, I don't want to drain the batteries too far and destroy them as I know can be done with LiFePO4. Does anyone know what would be a good voltage cut-off?
The other problem is that I don't have a proper charger, how can I go about charging the battery (just for testing purposes) without over or undercharging. If you look at this picture, I took her apart and I can't see any BMS . Don't I need one or is it just hidden from me? I have 12v automotive chargers and 24v SLA chargers on hand.
Last question, I know lots about SLA's, but I'm a complete newbie with Lithium. Currently, I have 48v20ah of SLAs on my scooter, from what I understand, 48v10ah of LiFePO4 should give me about the same range? I ask because if that's the case, I can get these 24v10ah batteries from work for $400CAN with a 3 year warranty, so adding the one I already got, I think that would be a pretty good deal. Personaly, I'd rather wait for another free one to come in, but I've been waiting for this one for 2 years. Thanks for the help!
