80V Forklift Lithium Battery Guide: Specs & Drop-In | EGbatt
Moving an 80V forklift fleet from lead-acid to lithium is one of the highest-ROI upgrades in a warehouse — no battery room, no watering, no change-out. This guide covers voltage, capacity sizing and what a drop-in LiFePO4 pack actually changes.
Why Lithium for Forklifts
- Opportunity charging: top up at breaks, no spare battery, no swap station.
- Zero maintenance: no watering, equalizing or acid handling.
- Full-shift power: voltage stays flat across the discharge, so the truck does not sag late in the shift.
- Safety: no gassing, no thermal runaway with a proper BMS.
Forklift Voltage Explained: 24V / 36V / 48V / 80V
| Nominal | Typical truck | Notes |
|---|---|---|
| 24 V | Walkie / pallet jack | Low duty, light load |
| 36 V | Reach truck | Mid duty, narrow aisle |
| 48 V | Counterbalance | Most common class I/II |
| 80 V | Heavy counterbalance | High capacity, outdoor / heavy |
Always confirm the voltage on the truck nameplate — an 80V pack will not drop into a 48V compartment.
How to Size Capacity (Ah)
Ah ≈ (avg load A × run hours) / DoD. A single-shift truck drawing ~80 A for 6 h at 80% DoD needs ~600 Ah; two shifts need 690–800 Ah
or opportunity charging during the shift. EGbatt 80V packs cover 400–690 Ah for typical 1–2 shift duty.
80V Models & Drop-In Replacement
- Direct compartment fit — same footprint and connector as the lead-acid block.
- Built-in smart BMS with CAN/RS485 telemetry for fleet charge management.
- IP-rated steel enclosure, forklift-grade cells rated for vibration and deep cycle.
For lower-voltage trucks, see our 48V server-rack and industry battery range; 80V traction packs are built to order from your truck model.
Charging Infrastructure
Lithium forklifts charge from standard industrial chargers (set to a LiFePO4 CC/CV profile) or opportunity chargers at break areas. You can usually decommission the lead-acid equalize/vented room entirely.
Lithium vs Lead-Acid for Forklifts
| Parameter | Lead-Acid | LiFePO4 |
|---|---|---|
| Cycle life | 1,000–1,500 | 3,000–5,000 |
| Charge | 8 h + equalize | 1–2 h / opportunity |
| Maintenance | Watering | None |
| Battery room | Required | Not needed |
| Weight (80V) | 1,000–1,500 kg | 600–900 kg |

Frequently Asked Questions
What voltage forklift battery do I need (24V/36V/48V/80V)?
Match the truck’s nameplate nominal pack. Walkie pallet jacks are 24 V, reach trucks 36 V, standard counterbalance 48 V, and heavy/high-capacity counterbalance trucks 80 V. Using the wrong voltage will not fit the compartment or the controller — always confirm first.
How long does an 80V forklift lithium battery last?
8–10 years and 3,000–5,000 cycles at 80% DoD for LiFePO4, versus 3–5 years and 1,000–1,500 cycles for a lead-acid traction battery — and the lithium pack keeps most of its capacity to end-of-life instead of tapering.
Can lithium replace lead-acid forklift batteries?
Yes. Drop-in 80V LiFePO4 packs use the same compartment and connector, need no watering, equalizing or dedicated battery room, and support opportunity charging. Most sites retire their spare-battery fleet and change-out equipment at the same time.
How do I size forklift battery capacity (Ah)?
From shift length and average draw: Ah ≈ (avg load A × run hours) / DoD. A single-shift truck drawing ~80 A for 6 h at 80% DoD needs about 600 Ah; two shifts need 690–800 Ah or opportunity charging. EGbatt 80V packs run 400–690 Ah for 1–2 shift duty.
What is opportunity charging for forklifts?
Instead of one full recharge, you top up during breaks and lunch. LiFePO4 tolerates partial state-of-charge and charges fast, so a truck never needs a battery swap — eliminating the spare pack, the change-out station and the lead-acid charging room.
How much does an 80V forklift lithium battery weigh?
A 400–690 Ah 80V LiFePO4 pack weighs about 600–900 kg, versus 1,000–1,500 kg for the equivalent lead-acid traction block — freeing payload and easing handling, with no acid or gassing.
