Flooded Batteries with 150Ah
Electrolyte separated and water froze - Been sitting all winter very cold weather for weeks!
Got it warmed up, and Electrolyte unfroze, topped up with water. #1 battery I could see the plates with no water!
Took 5-6L or 1.5G for all 4 batteries. #1 batt took the most water. I'd say
now using 4 chargers, typical L.A. chargers.
Canadian Tire Eliminator 6A
Battery Saver 8A
Forget the name 6A
Battery Saver 0.850A which is a float charge I believe.
Got rid of float and eliminator, now doing 28.0V on my Meanwell HRP @ 16A on two L.A.'s
Meanwell fans blowing steady and hard, voltage on psu is 28V and terminals 28V.
Im doing the magnet speed trick on these, cheaper alternative to reprogamming.
From what I gather the controller is a 500A Curtis, I assume any upgrade would be pricy. Thinking Kelly, Sevcon etc!
Thing was slow at 47V, hoping its better at 52V, will check with app gps speed. I gather from searching average speed should be 24mph, or 35kphish.
Oh another thing, first check of voltage, #1 batt was 11.80V, the others 5V, 3V, 1V. I freaked out! Thought they'd died. They are at around 13V now, got the meanwell set to 14Vx2 on 2S lead acid.
Its a 8km trip around cottage, cottage to docks , playground and beach 200m, maybe to other half of cottages is 2km.
Got no clue what a Wh/km would be, 50Vx150A=7500Wh say 75Wh/km, so 10km
