Instructions Must Be Read Before LiPo Pack Use
This battery pack is safe if you follow these instructions. However if you do not respect the warnings and follow the instructions closely, as with all batteries there is a risk of explosion, fire, smoke emission and poisoning. DO NOT leave a charging battery pack unattended.
Use only chargers for LiPo batteries that utilize a CC/CV method with a cut-off function. The charge cycle will begin with continuous current (CC). When a certain cut-off voltage is reached, the charger will hold the voltage constant (CV) while decreasing the charge current until the pack is fully charged. Your charger must be set to LiPo mode and you use specify the correct number of cells in the pack. A 2S pack has 2 cells, 3S has 3 cells, etc. Typical charge rates are 1C, for example: 2.3-Amps for a 2,300 mAh pack, 5.0-Amps for a 5,000 mAh pack, etc. We recommend any charge rate up to 2C; this means the maximum charge current is 10-Amps for our 5000 mAh capacity LiPo battery pack and 16-Amps for our 8000 mAh capacity LiPo battery pack. Do not use higher charge rates! Charge in LiPo Sack or similar safety device at all times. Cell balancing is a way of ensuring your Li-Po will deliver the maximum performance and capacity over time. Balancing is absolutely necessary and required each and every time you charge the battery pack! The balancing connectors (white) are: JST XH3 for 7.4V packs and JST XH4 for 11.1V packs. If using a stand-alone type balancer, balance pack DURING charging.
This LiPo battery pack must under no circumstances be discharged after use; doing so will permanently damage the pack. Do not disassemble packs. Do not continue to use a pack if an abnormality is detected, such as foul odors, pack deformation, discoloration and so on. If a pack gets wet it can potentially malfunction, do not use a wet pack. Do not solder directly to cell tabs.
SPC considers storage to be any time longer than 24 hours. When stored, this LiPo battery pack should be charged to approximately 30% to 40% of maximum capacity, then placed in a LiPo Sack and stored in a cool dry area. Check the LiPo battery pack at least every month during long term storage.
A LiPo battery pack is VERY sensitive to being over-discharged. The absolute minimum cut-off is 3.2 Volts per cell, however SPC strongly recommends a Low Voltage Cutoff (LVC) setting of 3.4 Volts to 3.5 Volts per cell. NEVER run the pack down until your RC car is just barely moving. Stop driving if you notice the vehicle slowing and/or the motor begins losing power. Remove the battery from the car and allow it to cool to room temperature before re-charging. After running the pack down to near the LVC cutoff, NEVER let the battery rest for a few minutes and then continue driving without first re-charging. Li-Po packs are designed for operating temperatures not to exceed 40°C.
Lithium Polymer batteries do not have a hard steel case like a NiMH battery. Instead a special aluminum foil encloses them, therefore they do not vent. If the integrity of the battery is compromised swelling will occur. If the battery pack is damaged and the case begins to expand, discontinue use immediately and dispose of battery pack properly. Do not touch any liquid if there is leakage.
Warranty
SPC LiPo packs come with a 90 day warranty from the date of purchase against manufacturing defects. To be considered for warranty a pack must be returned to SPC by the customer, along with a copy of the original sales receipt. If necessary, the pack will be sent back to the manufacturer for failure analysis. If this analysis shows the pack had a manufacturing defect, the pack will be replaced with a new pack. If however the pack shows signs of physical damage and/or the test analysis determines the pack was damaged by the operator, no warranty will be considered. No warranty will be considered for any pack that has been operated at a discharge (Amp-load) that exceeds that pack’s stated C, continuous discharge rating.
SPC is not responsible for battery pack damage and/or failure resulting from improper balancing and charging, improper discharging, soldering heat or not following these instructions. SPC is not responsible for any personal injury and/or damage involving this product. SPC will not warranty packs physically damaged as a result of abuse and/or impact of ANY kind. Also, never attempt to disassemble a LiPo pack; this is not only very dangerous but voids this SPC warranty.
