What Types Of Batteries Does BatteryBuilders Offer?
BatteryBuilders offers LiFePO4, NMC, and lithium-ion rack batteries tailored for EVs, solar storage, industrial, and marine applications. Their portfolio spans 12V–72V systems with capacities from 30Ah to 630Ah, featuring modular designs, advanced BMS protection, and temperature resilience (-20°C to 60°C). Custom solutions include heated cells for cold climates and CAN bus integration for fleet telematics. 72V LiFePO4 Battery Category
What lithium chemistries does BatteryBuilders specialize in?
BatteryBuilders focuses on LiFePO4 (LFP) and NMC (Nickel Manganese Cobalt) chemistries, balancing energy density (150–220 Wh/kg) and safety. LiFePO4 excels in cycle life (3,000+ cycles) for solar storage, while NMC offers compact power for EVs needing rapid discharge (up to 5C).
LiFePO4 cells operate at 3.2V nominal with 80% capacity retention at -20°C, making them ideal for off-grid systems. NMC, with 3.7V nominal, delivers higher specific energy (200–250 Wh/kg) but requires stricter thermal management. Pro Tip: Choose LiFePO4 for stationary storage due to lower degradation; opt for NMC when weight savings matter. For example, a 48V 100Ah NMC pack powers a delivery e-bike for 120 km vs. 90 km with LiFePO4. What’s the trade-off? NMC typically costs 15–20% more per kWh.
Are there modular rackmount options for data centers?
Yes, BatteryBuilders provides 2U-5U rack batteries (51.2V, 100–200Ah) with hot-swappable modules. These units support parallel expansion up to 1MWh and include SNMP/Modbus protocols for real-time health monitoring.
Their 5U PM-LV51200 model packs 51.2V 200Ah (10.24kWh) in a 19-inch rack, achieving 95% round-trip efficiency. Built-in self-heating pads maintain cell temps above 0°C during cooling failures. Pro Tip: Deploy rack batteries with a staggered charge schedule to reduce peak loads—critical for data centers with Tier IV uptime requirements. For perspective, a 50-rack cluster can sustain a 500kW facility for 8 hours during outages. How does scalability work? Each rack uses a master BMS that auto-syncs with new modules. Transitioning from diesel gensets? Lithium racks cut 40% off energy costs over 5 years.
| Model | Capacity | Cycles |
|---|---|---|
| PM-LV51200 5U | 200Ah | 6,000 |
| PM-LV5150 Pro 2U | 150Ah | 4,500 |

How do their EV batteries enhance performance?
BatteryBuilders’ EV-grade packs use prismatic NMC cells with ultra-low internal resistance (≤0.5mΩ), enabling 3C continuous discharge. Features include IP67 waterproofing and vibration resistance up to 5G for off-road durability.
A 72V 150Ah EV battery delivers 10.8kWh, adding 120–150 km per charge for cargo trikes. Proprietary cell stacking reduces internal impedance by 18% vs. cylindrical designs. Pro Tip: Pair with motor controllers rated for 20% above peak battery current to prevent MOSFET burnout. Imagine a food delivery fleet: Switching to these batteries reduces charge time to 1.5 hours (0–80%) with 100A fast charging. But what about cold starts? Built-in heaters pre-warm cells to 5°C in -15°C environments, avoiding voltage sag.

FAQs
Yes, if voltage matches. A 72V system replaces lead-acid 72V setups, but check motor compatibility—NMC’s 84V full charge may exceed brushed motor limits.
Do their solar batteries support off-grid inverters?
Absolutely. LiFePO4 packs integrate with Victron, Schneider, and Growatt inverters via CAN or RS485. Pre-configured cables ensure plug-and-play setup.
