80%depth of discharge for cycle-life claims

Traction duty is measured in minutes of high current, not hours of low current. A golf cart pulls several hundred amps from a stop, runs the pack down to 1.75 V per cell, then gets plugged in at lunchtime and run again. Deep-cycle plates and thick tubular grids survive that; a standby block with the same Ah label does not.

What decides life in this duty

Opportunity charging is partial-state-of-charge abuse

Plugging in at lunch and again overnight rarely completes a full charge, so the pack lives between 60% and 95%. Add a weekly full charge with a controlled overcharge, or the negative plate sulfates and the cart gets slower every month.

Cycle life claims need the depth attached

A 700-cycle figure at 50% DoD becomes roughly 350 cycles at 80%. Ask for the number at the depth the fleet actually runs, and ask whether it is IEC 60254 or an internal test, because the two are not comparable.

Fit is not cosmetic

Footprint, hold-down, terminal post height and cable lug size all have to match the tray. A block that is 5 mm too tall fouls the seat, and a taller post can arc against the frame after a hard stop. Send the tray dimensions with the RFQ.

What to put in the RFQ

System voltage and number of blocks per pack
Motor kW and controller current limit
Typical daily run time and charging pattern
Tray and hold-down dimensions, terminal type
Whether a lithium drop-in is being considered

Buyer questions

Will a lithium drop-in work with my existing charger?

Rarely without changes. A lead-acid charger finishes at 2.40 to 2.45 V per cell and holds it, which is above what a LiFePO4 BMS wants to see for long periods. Either fit a charger with a lithium profile or accept a shorter pack life.

How do I get more range without a bigger pack?

Check the end voltage and the tyre pressure first. Running the pack lower than 1.75 V per cell adds almost no range and costs cycles, and under-inflated tyres on a course with hills can cost more range than the last 10% of capacity.

Flooded, AGM or gel for a cart fleet?

Flooded tubular is still the cheapest per cycle where someone can water it monthly. AGM suits fleets with no maintenance staff and indoor charging. Gel tolerates deeper discharge but charges slower, which hurts fleets that need a fast turnaround between shifts.
