Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

MAX Rebar PJRC160 / 34G808 — 25.2V Li-ion Replacement Battery (JPL925)
This is a 25.2V, 3000mAh Li-ion battery pack replacing OEM part JPL925. It fits the MAX Rebar PJRC160 and 34G808 cordless rebar cutters. The pack slots into the same bay and communicates with the tool's onboard BMS via the original connector and data line.
- PJRC160 and 34G808 platform fit: Both models share the same 25.2V seven-cell architecture, connector pinout, and BMS data protocol. A single pack design covers both tools without any adapter or modification.
- Bench tested on actual hardware: We cycled this pack through repeated high-torque cut sequences on the bench. The BMS managed inrush current spikes at trigger pull without tripping and held the voltage rail stable through the full cut cycle.
- Rebar cutter break-in: On first use, run the tool through two cycles at partial cutting load before going to maximum jaw force. This lets the BMS log the motor's inrush current profile and set accurate overcurrent thresholds before sustained heavy use.
BMS cutoff on trigger pull during rebar cutting
Rebar cutters draw a sharp inrush current spike the moment the jaw motor engages. If the BMS has not yet profiled that spike — common with a new or freshly charged pack — it can trip the overcurrent threshold and cut power instantly. This is not a faulty cell; it is a protection response. Run two partial-load cycles first, and the BMS recalibrates its threshold to match the motor's actual start current.
Charger not recognising the pack after job site storage
If the pack sat unused for several weeks, individual cells may have drifted below the charger's acceptance voltage — typically around 2.5V per cell. Most chargers will blink red or show no response rather than begin a charge cycle. To recover, place the pack in the charger and hold the charge button for five seconds if the unit has a manual wake function; otherwise, try a different MAX-compatible charger that includes a recovery or trickle-start mode, then verify cell voltage climbs above 3.0V per cell before normal charging resumes.

Frequently Asked Questions
The MAX PJRC160 cuts out the instant I squeeze the trigger — battery or tool fault?
This is almost always a BMS overcurrent trip, not a defective cell or tool fault. The jaw motor pulls a sharp inrush spike the moment it engages, and a new or storage-rested pack hasn't yet logged that spike as normal — so the BMS shuts down as a precaution. Run two cuts at half jaw pressure first. After those cycles, the BMS profiles the inrush draw and stops tripping on a normal trigger pull.
The tool bogs and loses force halfway through a thick bar even though the battery shows charged — what's happening?
That's voltage sag under sustained load. As the jaw motor works through a hard cut, current draw stays high and cell voltage drops across internal resistance in the pack. If the contact rails between the battery and tool have any oxidation or debris, resistance rises further and the sag deepens. Clean both the pack terminals and the tool's battery bay contacts with isopropyl alcohol, then check that the pack locks firmly with no play — a loose fit causes intermittent rail resistance that kills cutting force mid-stroke.
Battery worked fine all summer but now the PJRC160 feels weak and slow in cold weather — is the pack failing?
Not necessarily — Li-ion internal resistance climbs sharply below 5°C, which reduces the current the pack can deliver and makes the tool feel sluggish. This is a chemistry characteristic, not a defect. Store the pack indoors overnight rather than leaving it in a site vehicle, and let it warm to at least 10°C before use. If performance recovers once the pack is warm, the cells are fine; if it stays weak at normal temperatures, that points to capacity fade from repeated shallow cycling.
