2.link the cables as the picture
When installing the batteries:
1. Please carefully place the cables and make them down, making sure
the cables not crossover the vent caps.
2. Always remove the negative(-) cable from the motor controller first,
and install it at last.
3. Do not over-tighten the battery nuts, because too much force would
damage the battery case.
Before charging:
Only add distilled water. If fluid is below
the top of the plates, add just enough to
cover plates.
After charging:
Check that the fluid level is appropriately
1/4 to 1/2 inch above the plates and 1/4 to
3/8 inch below the level is low. Add
distilled water carefully. Adding distilled
water after charging helps prevent boiling
over.

Normal tap water contains minerals
which are harmful to a battery;
therefore, refill only with distilled water.
3. Using a hydrometer, check the specific
gravity of the battery fluid in each cell
against the readings on the chart below.
Consult an AdvancedEV dealer if any low
readings are found.
