The recommended batter for an xs650 is the:
SHORAI LFX Lithium-Iron Powersports battery, Part Number: LFX14L5-BS12
4Ah PbEq 12V eq, "L" polarity, Case Type 5Sku: 4897034420685
The one you have is the: (which i'm going to get)
SHORAI LFX Lithium-Iron Powersports battery, Part Number: LFX14A2-BS12
14Ah PbEq 12V eq, "A" polarity, Case Type 2Sku: 4897034420081 It weighs 2lbs that's crazy
So the "A" or "L" polarity, refers to the side the positive is on the physical battery?
