![]() If you use it as-is, you'll surely destroy your batteries. The presets on it from the factory are crazy off. Even the apps and software to support it are 3rd party. To my knowledge, there's not even a manual of any kind available. There's very little technical support available. The Daly Smart BMS's have a well-earned, checkered reputation. For various reasons I didn't want to build two 100ah battery packs with two 100-120a Overkill BMS'S. Which BMS are you using?Thank you! Hope we get the same, reliable service from our pack. I am coming up on year 5 of my 160 Ah DIY pack and it is just humming along. No such concern with our converter.įWIW, we were able to get almost 85-90a of charge current by charging with both the PD 45a converter and our Renogy 40a dc to dc charger at the same time. As per BattleBorn Batteries, if a 14.6v single stage converter is inadvertently left connected to fully-charged LifePo4 batteries for weeks, months at a time it can overcharge the batteries. IMO this standard converter is a better match for our battery pack than the single-stage Progressive Dynamic dedicated Lithium 45a converter which produces a constant 14.6v. It produces a full 45a of charge current for nearly 90-95% of the charge cycle. It charges this pack to 100% SOC with zero issues. Use a Charge Wizard to lock it into bulk 14.4v mode for a fast bulk charge, then manually drop it to 13.6v when charging is complete. We use the standard 3-stage, Progressive Dynamic 45a converter in our truck camper. With a projected 2000-3000 cycle lifespan, odds are this battery will outlive us-lol!Įxcellent! What are you charging with?Thanks! two GC2's! Doubt we'll ever totally cycle this battery more than 30 times a year. This battery pack offers more than double the ah performance, 1/3 the weight and 1/2 the size vs. Lastly, these LFP cells and BMS easily fit inside a small, group 24 battery box. Bluetooth and low/high temp cut-off is icing on the cake. weight savings-a very big deal when you're trying to trim weight off the rear-end of a heavy truck camper. The two GC2's combined weigh almost 130 lbs! A 90 lb. ![]() Did I mention weight?! This LFP battery pack and BMS only weigh 40 lbs. No such issue with the LFP's-even down to 10% SOC. at 110a before activating the low voltage cut-off on our inverter (50% SOC). The two GC2's could barely muster 35-40 min. I can power a ceramic space heater (110a load) on high for at least 90-95 minutes (down to 15-20% SOC). These LFP's easily supply more than double the usable ah, especially when under very high loads (>100a). ![]() I might add the GC2's we replaced were only 2 years old, well maintained, probably cycled less than 30 times, and performed like new batteries. ![]() Have no idea how this battery pack is going to work out for the long haul, but for now it massively outperforms our two GC2's. Top balanced the cells before doing a whole slew of discharge/charge/temp tests to verify all the various cut-offs worked properly on the BMS. It was a bit of a learning curve understanding and adjusting all the BMS presets, but managed to get everything working smoothly. Didn't want to wait 4-8 weeks ordering from China, so we purchased the cells and BMS from US distributors (~$750 probably could have saved $150-$200 ordering it from China however, nearly zero recourse if you have any problems). About 2 weeks ago decided to get adventurous and build our own LifePo4 200ah battery pack instead. Was right on the edge of purchasing a pair of 100ah BB or LifeBlue LifePo4 batteries ($1600-$2100) for our truck camper.
