Purchased 3 of these batteries as well as 5 of the 4s (no issues with the 4s) All 3 of the 2s batteries have swollen badly, always following storage charging and unplugging when done with a day of driving...Usually no more the 10 minutes each session. All 3 no longer reliable. Have only used them for about 6 cycles each. Batteries should not swell at this price point after 6 cycles. Terrible battery. Looking for replacement from Amain/Manufacturer. Update: Purchased 4 more in Feb. 2021 ran only one cycle through all four and all four are swollen. Thought I got a bad bunch last time but the same issue has happened with this set. Again looking for replacement from Amain/Manufacturer.
This battery is terrible!!!... I hate to say it considering I've great results with the Gens Ace shorty packs but its true. I'm using this battery on an arrma voltage & Traxxas TRX4 with a BRUSHED 12t 550 motor & hobbywing BRUSHED ESC. This battery SHOULD be over rated for my rc. The 1st battery I bought, it had an issue with one of the cells & the battery charger would throw an error, it also had swollen & it was very noticeable all within a few charge cycles. Luckily my battery was under warranty & I got a replacement directly from Gens Ace. Now I'm on my 2nd battery which is basically the warranty replacement & this battery has also started to swell but not as bad. The cells are within spec, it takes 8000+ MAH of charge but I honestly would not trust this battery in a high power type rc.
Had ordered 2 of these packs, 1 out of the box was unbalanced and would not charge and the other puffed up on its first cycle...not bashing Gens Ace as I own many of their lipo packs with no problems but these 2 were no good...replacements are working perfectly normal. Thanks to the awesome crew at A Main!!!!
Used the pack once in a dr10 drag car with 4.5t motor held up good when done with testing an tuning still had alot of mah in pack going to be ordering more of them soon
I took this battery racing I test and tuned with it I done 4 pulls on it then we raced I took the battery out and it was like a round ball in my drag slash may have been just bad from start some times it happens..
Reviews are sharply divided. Several owners report swelling, puffing, or cell imbalance, sometimes after only one to six cycles, with some packs unbalanced out of the box and others swelling during storage charging. Affected buyers mention replacements or warranty claims, and some replacements were reported to perform normally. Other reviewers, mostly in SCT and drag applications, praise the power, runtime and balance of the pack and say they would buy again. Reviewers note a 5mm post connection layout that differs from some other brands, and one reviewer said wiring was not included. The recurring problem is cell swelling and balance failures.
