About This 【BUILT-IN 20A BMS 】 Deep cycle battery has built-in 20A BMS to protect it from overcharge, over-discharge, over-current, and short circuit with excellent low self-discharge rate. With high temp cutting off prevents charging over 167 °F (75°C). If the package you received does not contain M5 screws, please communicate with us first, thank you very much (Not a starting battery, not suitable for use as a power battery） 【Advanced Lithium Iron Technology】 20Ah lithium battery manufactured by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance and greater power. Excellent cycle performance, fast charging and discharging, charging efficiency up to 100%, and high output power. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. Supporting expansion for up to 4 series & 4 parallel and suitable for electric energy storage 【Exceptional Longevity & Lightweight】 Our LiFePO4 lithium iron batteries provides 5000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times than the standard lead-acid batteries. Helping to minimize replacement cost and reduce total cost of ownership. And the weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity, so you can carry it more easily 【Safety & Green Battery】 The stable Lithium Iron Phosphate chemical structure makes LiFePO4 battery not burn or explode even at high temperature, short circuit, impact and drop. Highest-level safety based on UL Testing Certificate for the cell inside the battery. And it does not contain any heavy metals and rare metals, which called green battery 【Multi-Application & Technical Support】 With no acid in the lithium ion battery, you can safely mount it in any position. This makes li-ion batteries perfect for marine, RV, campers, travel trailers, and off-grid applications! Vatrer Power provides 24hrs friendly and professional customer support, any questions please contact us. 【NOTE】 The 20Ah battery adopts our latest appearance design. All the configurations are the same as the previous version. It can still be connected in series or parallel with the earlier version.
