Can I charge my Luna 52V Dolphin pack with a 285W solar panel by using this MPPT Solar Charge Controller set at, say, 56V or 52V? Will it damage the battery?
Thanks, I'm pretty wet behind the ears.

kdog said:the main thing is that you need to know the exact voltage to charge to.
given by #cells x 4.2v for li-ion and #cells x 3.6v for lifepo4
what is the configuration of the luna battery?
im guessing its a 14 cell li-ion so its max charge is 58.8v
this is an absolute max. if you accidently charge above that to say 63v you will have destroyed your battery and may have a potential fire on your hands at some stage (maybe down the track)
you can undercharge but the BMS wont balance until nearly full.
can you set V accurately on your MPPT charger? 56 or 52 is nowhere near accurate enough

Sunder, can you give an update on the 7210A..Sunder said:I've unfairly maligned this charger. My apologies.

Is it still working reliably ?
Does it stop the charge when a min current level is reached, or is it just time based ?
Are you still running it from a power supply , rather than solar ?
Any other problems with it to date ?
Thanks
