This battery lasts a surprisingly long time, even with heavy use on my saw and drill. It’s a great value compared to buying an extra original. The build feels solid, and it locks securely into the tools. Definitely a smart investment for anyone with Multivolt tools. Read more

So far, it seems to be the equal of the Metabo Mulivolt battery for a much lower cost. Update from 5 to 1 stars: This will be long, but bear with me. In 2008 I started switching from nicad to li-ion cordless tools. Having been a fan of Hitachi pneumatic nailers, I bought Hitachi 12v, then 18v tools. I've had 7 Hitachi 12v batteries and over a dozen Hitachi and Metabo 18v batteries. All 7 of the 12v and all but 2 of the 18v are still in service. Needless to say, I've been impressed with their longevity, especially considering how quickly nicads would die. About 2 years ago, Metabo had an offer for a free multivolt battery with a tool purchase. I wound up with 2 of these that I used in an 18v circular saw for improved performance. I then upgraded 2 tools to 36v and added 2 more Metabo multivolt batteries and a fast charger. After a year the multivolt batteries started dying off. I replaced one with a Xeanerol and was having good results with it. Eventually, 3 of the 4 Metabo multivolt batteries have died and I bought another Xeanerol. The new one would not fit in any Hitachi or Metabo charger. Thinking it was defective, I asked Amazon to replace it, which they did. The replacement doesn't fit any charger either. This week, the first Xeanerol died, thus the 1 star rating. Does anyone make a reliable multivolt battery? Read more

This battery packs a punch and lasts all day long! What's even more impressive, is the cost given the performance. This is especially significant when compared to OEM Hitachi / metabo batteries, which can cost a fortune. It works with all (circular saw not pictured) the tools and provides ample power to finish even the toughest of jobs. Read more

Update after using this pack for a couple months: So primarily use it in my 18v hammer drill and 36v 7 1/4 circular saw, works flawlessly in both tools, charges fine. The Lishan 2170LA batteries are definitely legit, I certainly get the full 4Ah@36v and plenty of power to go with it. These 8Ah packs are a bargain, the cells in them perform better than OEM unless you steo up to the TPWR packs which will run you$200, not worth it IMO. Purchased this 4/8Ah pack as a backup and considering the price it would be a fantastic deal if the pack actually contained 21700 cells. Received item today, first thing I noticed was the weight - it definitely has 21700s in it. First thing I opened up the pack to confirm what cells are being used and check on the build quality. To my surprise this pack is using 10 Lishen 21700 4000mAh LR2170LA (Purple) (Google the item, there is a pretty good detailed review out there on their performance). Reading up on the cells they got about 3.7ish mAh capacity and could sustain 35a discharge (rated at 45a, but causes heat issues). They're connected to a BMS made for 36v18v (found that this is sold on Alibaba part is DL-RL 36a18-21700 v1. 0). The battery to battery connections look good, solder points look pretty good as well doesn't look like someone just threw it together, looks well thought out and pretty well designed for a 8Ah 21700 cell pack that sells for only $60. Pictures of the interior bits attached, highly recommend giving this a try if you have some metabo tools. It's cheaper than buying metabos plain 4Ah 21700 pack. I am genuinely impressed they actually used branded cells, 21700s at that (I expected 18650s just based on previous experiences with 3rd party batteries). Oh it also works with metabos rapid charger, fan spools up, it beeps when charging is complete and stops charging the battery as well. It acts like a legit battery. Read more
