About this replacement
Spypoint Bloc Pile / SOLAR-DARK / LINK-S-DARK — 7.4V Li-Polymer Replacement Battery (LIT-09)
This is a 7.4V, 1900mAh Li-Polymer battery that replaces the Spypoint LIT-09 original. It fits the Bloc Pile, SOLAR-DARK, LINK-S-DARK, Link-S, and over ten additional Spypoint trail camera models. Dimensions are 85.50 × 54.00 × 15.40mm — a direct physical match to the original cell.
- Shared platform across Spypoint cellular and standard models: These cameras run the same 7.4V power rail and LIT-09 form factor regardless of whether they use cellular transmission or standard local storage. The connector pinout and BMS handshake requirements are identical across the lineup.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Spypoint LINK-S unit. The BMS accepted charge without fault flags, held voltage above 7.0V through sustained draw, and cut off cleanly at the low-voltage threshold — no false triggers.
- Cold-weather deployment tip: Li-Polymer cells lose 15–25% usable capacity at 0°C and up to 40% at –20°C. If you're setting cameras in freezing conditions, carry the battery in an inner pocket and install it just before mounting the unit — a warm cell holds significantly more charge than one that's been sitting in a frozen housing overnight.
Why Spypoint trail cameras stop triggering in sub-zero temperatures
Li-Polymer cells don't fail in the cold — they throttle. Internal resistance rises sharply below freezing, which means the cell can't deliver the brief current spike the camera needs when the PIR sensor fires and the shutter triggers. The BMS reads this as an undervoltage condition and shuts the circuit before a photo is taken. The battery may still show charge on the indicator but can't sustain the load. Installing a warm cell before deployment is the most effective fix — not a higher-capacity cell.
Camera won't power on after sitting through a cold winter
Li-Polymer cells self-discharge slowly over time, and cold accelerates this. A camera left unattended through winter can return a cell voltage below 6.5V — the minimum the BMS needs to initiate a boot sequence. At that point, the camera shows no response even when charged. Connect the battery to a charger rated for Li-Polymer and let it trickle charge for 30–60 minutes before attempting to power the camera on. If voltage doesn't recover past 7.0V after a full charge cycle, the cell has been in a deep-discharge state too long and replacement is the next step.
