No Manual

Didn't get to check the performance of the charger because I guess my battery is broken. Still weird that the charger came with no paperwork besides the packing slip.

Millertech 36v 15a battery charger and battery.

Replaced 3, 12 volt 31 series lead acid batteries with 1, 36v sport series battery, and 3 bank Minnkota charger. Change over went very smoothly, with no problems.
Battery, and charger both worked flawlessly, New battery, and app are a pleasure to use. Plenty of power and app is very easy to use. The only things I would change would be to make the power cord to the charger a little longer, and include rubber mounts on charger. Great products and I look forward to many years of service.
Thanks Millertech.
