What Battery Fits A Columbia Par Car Cart?
Columbia Par Car carts typically use 48V or 36V deep-cycle lead-acid battery systems. The exact configuration depends on the model year: older units often require six 8V batteries (48V total), while newer versions may use four 12V batteries. Lithium-ion upgrades like 48V LiFePO4 packs (50Ah–100Ah) are compatible with voltage-regulated controllers, offering 30% weight reduction and 2,000+ cycles. Always verify terminal type (SAE or L-type) and tray dimensions before replacement.

How to determine voltage requirements for Columbia Par Car?
Check the existing battery bank configuration. Six 8V units create 48V systems (common in post-2005 models), while four 12V batteries indicate 36V setups. Use a multimeter on charger ports—functional systems show 44–50V (36V) or 58–64V (48V). Pro Tip: Lithium conversions require matching BMS cutoff voltages to prevent controller errors.
Columbia Par Cars use series-wired batteries, where voltage adds across the chain. A 48V system with six 8V lead-acid batteries delivers 250–300Ah capacity. For example, replacing these with a 48V 100Ah LiFePO4 battery cuts weight by 150lbs while maintaining range. Warning: Mixing battery chemistries destroys BMS units—never combine lithium and lead-acid in the same system.
What physical dimensions fit Par Car battery trays?
Standard trays accommodate L16 or GC2 cases (10.3″L×7.1″W×10.9″H). Lithium alternatives like Redway’s RL-48V100AH (19″×8″×11″) use adapter plates. Measure existing battery box clearances—some retrofit kits require ≥0.5″ side gaps for heat dissipation. Pro Tip: 3D-printed spacers secure smaller lithium packs in legacy trays.
| Battery Type | Dimensions | Weight |
|---|---|---|
| Lead-Acid (8V) | 10.3×7.1×10.9″ | 63lbs |
| LiFePO4 (48V) | 19×8×11″ | 55lbs |
Can lithium batteries replace original lead-acid units?
Yes, using 48V LiFePO4 packs with voltage-compatible BMS. Ensure the lithium battery’s continuous discharge current (100A–200A) matches the motor’s peak draw. Install a lithium-spec charger (58.4V cutoff vs. 56V for lead-acid) to prevent undercharging. Real-world example: A 48V 80Ah lithium pack outlasts 48V 225Ah lead-acid in cycle count (2,000 vs. 500 cycles) despite lower Ah rating.

What connectors work with Columbia Par Car systems?
Standard SAE posts (5/16″) for 36V models and L-type terminals (3/8″ bolts) on 48V systems. Lithium upgrades often use Anderson SB175 connectors—rated for 175A continuous. When rewiring, replace all series cables with 4AWG copper (lead-acid) or 6AWG (lithium) to handle increased efficiency. Pro Tip: Apply antioxidant gel on terminals to minimize voltage drop.
How does temperature affect battery choice?
Lead-acid loses 40% capacity at -20°C vs. lithium’s 25% loss. Par Cars in cold climates benefit from LiFePO4’s built-in heaters (0°C–45°C operational range). In hot regions, ensure battery compartments have ≥2″ ventilation gaps. Did you know? Lithium batteries self-discharge 2% monthly vs. lead-acid’s 5% weekly loss.
| Factor | Lead-Acid | LiFePO4 |
|---|---|---|
| -20°C Capacity | 60% | 75% |
| 50°C Cycle Life | 200 cycles | 1,500 cycles |

FAQs
Lead-acid: 2–4 years (500 cycles). Lithium: 8–10 years (2,000+ cycles) with proper 80% DoD management.
Can I add extra batteries for more range?
Only with controller reprogramming—exceeding voltage limits fries MOSFETs. Capacity increases require Ah-matched parallel banks.
Do lithium batteries require special maintenance?
No monthly equalization needed. Just keep terminals clean and store at 50% charge if unused >3 months.
