- RL-BI003 LED battery capacity indicator is a helpful device to display the real-time battery power left,battery state of charge/discharge status.
- It can be worked on DC 36V Lead acid battery(but not Trojan), and remind you the low battery by flashed LED bars.
- This battery charge meter owned favorable water resistence IP65.

LED Battery Power Indicator
Display power status by 10 LED bars( 1 red 2 yellows 7 greens)
- It get accurate reading of how much battery have left, each bars indicate 10% power percentage.
- It remind you the low battery when power during 10% to 20% left by flashed LED bars.
- Applicable battery type: Lead Acid(not Trojan).
Runleader has established a complete laboratory for testing and improving the product's quality

Yellowing Resistance Testing
It can keep good working condition from simulative strong UV ray lightening.

Drop Testing
Favorable anti-vibration performance can suffer strong vibrations when the equipments is working.

High & Low Temperature Testing
It can works well in temperature environments temperature: -40 °C - +70 °C.

Salt Spray Testing
It can keep good working condition under 5% strength salt spray solution about 16 hours.

Anti-vibration Testing
It can keep the housing and LCD display window in good condition upon vibration amplitude 1.52mm after 6 hours testing period.

Anti-static Inteference Testing
It keep the good working condition upon a limited voltage, static interference and transient overvoltage test. It also pass another considerate test for each functions sections and attached accessories.
