## Description

Product Description

Review: Brilliant! - Corrected an issue I had with cheap unbalanced lifepo4 batteries. Brilliant example of design and functionality. People here seem to be confused in some of their reviews: - Doesn’t turn on? Its only supposed to be on greater than 27.2 volts on charging and discharging. Its there to correct the last 10-15% of the charge cycle. - Can’t see it doing anything? Get a volt meter, look at your manufactures BMS app at individual batteries or the green light on the front. - Can’t tell the difference between cell balance and battery balance? The internet echo-chamber is 80% wrong on this point because unknowledgeable people don’t know the difference and use the terms interchangeably. Cell balancing is always done by the BMS, so check your battery app. Battery balancing is at battery level, and only when there are >= 2 12volt batteries in series. - Brought it because it was blue? Its good protection to extend the life of lifepo4’s by avoiding over-charge and over-discharge. You batteries will live years longer and not swell up/degrade as fast due to over-charging. - Lights never come on? You’re not charging at the correct voltage. - Green light always on? That means it’s working great and already done it's job. - Red lights flashing a lot / all the time above 27.2 volts before green light goes on, or never comes on? One or more of your batteries could be defective already or your series string is mismatched. Different brands etc. It's a battery fault.
Review: Balancer for 12v batteries in series. - It balances 2x 12v batteries connected in series
